Glossary of Terminology
Amplifier
see Headphone Amplifier

Analog
Generally, a mechanism that represents data using a continuously changing variable. In audio, usually a voltage that continuously tracks and represents sound pressure level.

Balanced Headphones
Balanced headphones are headphones that have been wired for balanced, or differential drive operation. Normally headphones have three connections: a left and right signal that is connected to the + side of the driver coil and then a common return for the - side of the driver coil. This common connection and its contact and other resistances to ground allow a small amount of cross-talk between channels to develop. Balanced headphones have four connections with a normal and inverted audio signal driving the = and - side of the driver coils for each channel. While this method requires special four-channel balanced headphone amplifiers, it completely removes the opportunity for cross-talk at the headphones and effectively doubles the slew rate of the amplifier/headphone system providing significantly cleaner sound.

Behind-the-neck
Behind-the-neck headphones have a headband the goes around behind the neck rather than over the head. These headphones are most commonly used as excersize headphones as thay are quite stable during activity and can be worn with a helmet, but they are also used when listeners don't want to muss up their hair, or when wearing a hat.

Bright
A term meaning generally that a sound has strong treble. Would be harsh or tizzy in the extreme.

Circumaural
Literally meaning "around the ear," circum aural headphones have ear pads that completely surround the ear, and ear cups that completely enclose the ear.

Closed
Closed headphones are also commonly called 'sealed' headphones, and are designed to block out environmental noise using a passive acoustic seal. Full size closed headphones provide about 10dB of isolation, mostly in the higher frequencies. Earpad closed headphones provide somewhat less isolation, strongly dependent on their design and the shape of your ear. In-ear headphones are a closed design in which the ear-pieces seal in the ear canal providing about 23dB of outside noise attenuation, and are the highest isolation of headphone type. Noise-cancelling headphones are typically closed designs that add electro-acoustic techniques to attenuate noise more than a passive seal would provide.

Coaxial
Many digital to analog converter (DAC) products have a "coaxial digital" input. This is a 75 Ohm S/PDIF digital audio input. The word "coaxial" specifically refers to 75 Ohm cables which typically use a coaxial construction, which refers to a center conductor and an outside conductor which completely surrounds the center conductor. Both conductors share the same center axis and are tharefor called "co-axial."

Coherent
Technically, when all spectral components of the audio are passing through the system at exactly the same time. When audio is coherent, imaging is precise and stable with instruments clearly defined and natural sounding. When incoherent, may become edgy and hard sounding, lacking image depth.

Crossfeed
An electronic circuit that serves to make the audio image on headphones more like that heard on speakers. It takes the signal from each channel, delays it for a few hundred microseconds, and crossfeeds it over to the opposite channel to mimic the acoustics of the left speaker sound reaching the right ear and vice versa. It both improves the audio image on headphones, and reduces listening fatigue.

DAC
A DAC is a Digital to Analog Converter. Music is stored as a series of numbers on CDs and in computer files. Each number represents a sample of the instantaneous voltage value of the audio signal at a point in time. Samples are taken many thousands of times per second (44,100/sec for cds), and have a resolution of 16 or 24 bits typically. A DAC takes this stream of digital numbers from a CD player or computer and converts it to an analog electrical signal that can be amplified and used to drive headphones or speakers.

Damping Factor
Typically the input impedance of a speaker/output impedance of the amplifier. An 8 Ohm speaker driven by a power amplifier with an output impedance of 0.8 Ohms would have a damping factor of 10. Typically, damping factors of 10 or more are considered good.

dBr
"Amplitude (dBr)" is listed on the Y axis of frequency response measurement data. "dbr" stands for Decibels- relative. The graph is showing the amplitude of each frequency's response relative to the amplitude of the other frequencies, not the actual number of decibels measured at each frequency.

Digital
Generally a system using binary data (ones and zeros) to represent information. In audio, a digital signal is a series of binary numbers that represent the sound pressure level sampled in a series over time.

Digital Inputs
Any input to a digital to analog converter (DAC); for example USB, or S/PDIF Toslink optical or coax digital inputs.

Distortion
Any new feature in a signal due to some imperfection in the device through which it passes. For example, putting in a 1000 Hertz tone, and getting a small amount of 2000 Hertz tone out along with the original 1kHz tone.

Driver
The element inside the headphone that converts an elecrical signal into sound pressure that is heard. Most headphones use a dynamic driver which is a coil of wire suspended in a magnet and attached to a diaphragm. Much like a very small speaker cone.

Ear Canal Headphone
Ear canal headphones are called in-ear headphones but are commonly known by numerous terms including: in-ear monitor, IEM, ear canal headphones, earphones, and canalphones. In-ear headphones are inserted into and seal the ear canal, and provide the highest amount of isolation from outside noise of any headphone type including noise-canceling headphones. There are two types of in-ear headphones: deep sealing and shallow sealing. With deep seating in-ear headphones the tip of the earphone goes in about half the length of the ear canal and seats in the boney section of the ear canal; this type provides about 23dB of isolation. Shallow seating types seal near the entrance to the ear canal and provide about 15dB of isolation.

Earbud
Earbud headphones have small earpieces that are positioned in the small cupped area (concha) around the entrance to the ear canal in your outer ear (pinna). They most commonly simply rest in the concha, but some heave headbands and/or ear clip features to improve wearing stability. Earbuds are similar in size, but should not be mistaken for in-ear headphones, which seal in the ear canal and typically sound much better.

Earpad
Properly known as supra-aural headphones, earpad headphones have ear-pieces are sometimes literally flat pads against the ear, but can also be shallow bowl shaped, or deeper ear cups that are too small to fully surround the ear.

Earphones
Some manufacturers have begun to call in-ear headphones 'earphones'.however a more propper term for this type of headphone is 'in-ear headphones," but they are commonly known by numerous terms including: in-ear monitor, IEM, ear canal headphones, earphones, and canalphones. In-ear headphones are inserted into and seal the ear canal, and provide the highest amount of isolation from outside noise of any headphone type including noise-canceling headphones. There are two types of in-ear headphones: deep sealing and shallow sealing. With deep seating in-ear headphones the tip of the earphone goes in about half the length of the ear canal and seats in the boney section of the ear canal; this type provides about 23dB of isolation. Shallow seating types seal near the entrance to the ear canal and provide about 15dB of isolation.

Efficiency
Headphone efficiency is the measure of the relation ship between input signal level and how loud the headphones play. This can be a rather confusing measure and can be expressed in numerous ways: dB/Watt; dB/mW; dB/Volt. Some in-ear headphones have very high efficiencies (~120dB/mW); difficult to drive full size headphone may be in the 90dB/mW; headphones to be driven by portable players should have about 95dB/mW or better efficience, and a 100 Ohm or lower impedance.

Filter Switch
This switch engages a filter that makes the sound slightly brighter (more highs). It is there to compensate for the crossfeed which causes in increase in low frequencies. The amount of increase in low frequencies is dependent on how much information is common to the left and right channel; the more common information the more the bass will boost through the crossfeed. Over time, our electronics circuits have gotten faster, and we've found less bass emphasis occurs when the crossfeed is switched on, and we have found the need to use this switch is substantially less.

Frequency Response
A systems gain at various frequencies. "Flat" frequency response is when the gain is constant at all frequencies. For example, a gain of two at both 20 Hertz and 20kHz, and at all frequencies in between.

Full size
Also called "circumaural," full-size cans have earcups

Gain Switch
A coarse volume control for headphones of differing impedance. Roughly, set to low for 10 to 50 ohm; medium for 50 to 200 ohm, and high for 200 ohm and up. Headphones vary widely in their impedance and efficiency. In order to have the amplifier volume control operate somewhere between the 12 o'clock to 3 o'clock to achieve a normal listening level with the wide variety of headphones commonly encountered, a gain switch is used to adjust the gain range over which the amplifier operates.

Harmonic Distortion
Distortion artifacts that are exact integer distances higher in frequency than the originating tone, usually a result of non-linearities in the transfer function of an analog electronic device. For example: 1kHz might yeild a little distortion at 2kHz, 3kHz, 4kHz, 5kHz, etc. Typically, it is thought the even harmonics (2, 4, 6, 8) sound better than odd harmonics (3, 5, 7, 9). This is somewhat true, but a gross oversimplification of the subject.

Headphone Amplifier
A headphone amplifier is a miniature audio power amplifier specifically designed to drive the miniature audio drivers in headphones. Headphone amplifiers work essentially identical to power amplifiers used to drive speakers except they are much lower power and need to be capable of driving a wider range of impedance (~20-600 Ohms) than speaker amplifiers (4-8 Ohms). Headphone amplifiers typically range between 0.1 to 1 Watt, and about 0.2 to 2 Ohms output impedance.

Headphone Efficiency
A measure of how much energy it takes to drive headphones to a given listening level. Can be stated in numerous ways but generally in the form of: dB/volt or dB/Watt.

Headphone Sensitivity
see Headphone Efficiency

Image Depth
The ability of an audio system to portrey sounds in front of, and behind each other. Essentially, front to back imaging. Audio systems typically trade off a punchy sound for a deeply layered sound; a very few do both well.

Image Width
The left to right width of the audio image. Typically within the boundry of the left and right speaker in a two channel audio system, but may be all around in a multi-channel (surround-sound) system.

Imaging
see Soundstage

Impedance
The sum of both resistive and reactive impeding forces of a load. Headphone impedance commonly changes with frequency, and would become somewhat inductive or capacitive at different frequencies.

In Ear Monitor
Ear canal headphones are called in-ear headphones typically but are commonly known by numerous terms including: in-ear monitor, IEM, ear canal headphones, earphones, and canalphones. In-ear headphones are inserted into and seal the ear canal, and provide the highest amount of isolation from outside noise of any headphone type including noise-canceling headphones. There are two types of in-ear headphones: deep sealing and shallow sealing. With deep seating in-ear headphones the tip of the earphone goes in about half the length of the ear canal and seats in the boney section of the ear canal; this type provides about 23dB of isolation. Shallow seating types seal near the entrance to the ear canal and provide about 15dB of isolation.

Input Impedance
The effective resistance of the input to a device. Essentially, how hard a load it is to drive. Most good electronics have an input impedance in the many thousands of ohms, and are easy to drive.

Isolation
The ability of a pair of headphones to block outside sounds so that the listener can hear the music on the headphones more clearly. Can be measured as a broad band reduction in amplitude in a single number in dB; or shown as a graph indicating the amount of attenuation over the audio spectrum.

Laid Back
An audio presentation that has a sense of ease and distance; i.e. in the tenth row instead of the first row of an audience. Generally meaning that it lacks agressive high frequencies; slightly soft sounding.

Linear Amplifier
A broad category of electronic amplifiers with very linear gain curves. Usually solid state, class A/B push/pull amplifiers. Generally as opposed to single output device, class-A amplifiers that have more non-linear gain curves.

Listening Fatigue
The result of your brain having to struggle to properly place (localize) sounds in an artificial listening environment like speakers and headphones. Generally much worse on headphones, and can be minimized with a crossfeed circuit.

Noise Cancelling
An electro-acoustic system which uses a microphone in the earpiece and an electronic circuit to produce a signal which is fed into the headphone which counter balances and cancels outside noise to provide acoustic isolation.

Open
Open headphones are also commonly called 'open back' headphones, and are designed to leak sound in and out. This allows the headphones to generate a larger 'soundstage' for better 'imaging' of sound. Since sound is leaked out they are not as suited for noisy environments or where you may be in close proximity to others who may be bothered by sound.

Op-Amp
An Operational Amplifier is technically an electronic amplification circuit with an inverting and non-inverting input and an output, ready to be configured to act in a variety of different ways using various methods. Commonly, Op-Amp is used to describe a type of integrated circuit chip that performs these functions.

Optical
Optical most often refers to a digital audio connection which uses light instead of an electricity to pass a signal. Optical cables (sometimes called Toslink cables) use a clear plastic fiber internally to pass the light on which the digital signal is carried. These connections have the advantage of not carrying an electrical signal and may help prevent ground loops and transfer of noise, and are immune from RF interference. Unfortunately, optical cables can vary widely in quality; we recommend using higher quality optical cables for runs longer than three feet.

OTL Tube Amps
OTL means "Output Transformer-less." Tube amplifiers typically use transformers to convert the high-voltage/low-current signals at the tube output into the low-voltage/high-current signal needed to drive the speaker. OTL amps use capacitive coupling, or D.C. coupling instead.

Output Impedance
The effective resistance seen by a load as it "looks back into" the output of an amplifier. The lower the output impedance of an amplifier, the more it shorts out (damps) the energetic reactions of the load. Good solid-state headphone amps have about one Ohm output impedance.

Power Amplifier
A power amplifier increases the amount of energy in an audio signal from a low level to a power level high enough to drive a pair of speakers. Power amplifiers typically have a fixed gain (amount of amplification) and volume is controlled by a pre-amp or headphone amp prior to being sent to the power amp. Power amplifiers are typically rated in Watts delivered into 4 or 8 ohms. Typical power ratings for desktop speaker amplification is about 25-100 Watts into 8 Ohms. 750 Watts is about 1 horse power.

Power Supply
In audio, the circuitry that converts the A.C. wall voltage into usable D.C. supply voltages inside the device. "Stiff" power supplies are desirable, and are those that change very little as the current demand from other circuits change.

Punch
An audio systems ability to deliver significant pressure changes while remaining coherent. An overly punchy system will often lack finesse to deliver depth of imaging.

Resonance
The characteristic of a physical systems ability to "ring." A bell is resonant. Electrical circuits can also "ring" as in an oscillator, but resonant circuits can also be used to create filters. Reducing unwanted resonance when driving headphones is generally accomplished though damping. Proper balance between the instability of resonance and reduced slew rate due to over damping is called "critically damped."

S/PDIF
S/PDIF stands for "Sony/Philips Digital Interconnect Format," and is an industry standard specifying the hardware connections (RCA, BNC, or Toslink) and "data link layer" protocols for digital audio transfer in consumer electronics. It is a sub-set of a larger standard for digital audio transfer, IEC 60958, which is also known as the "AES/EBU" standard.

Sealed
Sealed headphones are somewhat more commonly called 'closed' headphones, and are designed to block out environmental noise using a passive acoustic seal. Full size closed headphones provide about 10dB of isolation, mostly in the higher frequencies. Earpad closed headphones provide somewhat less isolation, strongly dependent on their design and the shape of your ear. In-ear headphones are a closed design in which the ear-pieces seal in the ear canal providing about 23dB of outside noise attenuation, and are the highest isolation of headphone type. Noise-cancelling headphones are typically closed designs that add electro-acoustic techniques to attenuate noise more than a passive seal would provide.

Semi-Open
Semi-Open headphones are also commonly called 'semi-open back' headphones and are situated somewhere between 'open' and 'closed' designs. Often they limit the amount of sound leakage via vents or holes to achieve a balance between both designs.

Solid State
A broad categorization of active electronic circuitry that use transistors of various types (NPN, PNP, FETs, J-FETs, and analog integrated circuits) to provide gain. Usually used to differentiate against vacuum tube based designs.

Soundstage
The ability of an audio system to reproduce the position and sense of space in which the instruments and sound sources are placed. Good imaging is when you can "see" with your ears the players standing there.

Square Wave Response
An audio test signal which alternates between two D.C. levels. Used to visualize the systems ability to pass a wide range of frequencies in proper time-alignment.

Supra-aural
Literally meaning "on the ear," supra-aural headphones rest against the outter ear and are generically termed earpad headphones. Ear-pieces are sometimes literally flat pads against the ear, but can also be shallow bowl shaped, or deeper ear cups that are too small to fully surround the ear.

Transient Response
The ability of a system to rapidly change voltage and/or acoustic pressure, and settle properly to target voltage/pressure. Also related to high slew rate, and the ability of the system to pass all frequencies at the same rate.

Transistor
A small electronic device which can provide electical signal gain in circuit construction. Manufactured using silicon or gallium arsinide semi-conductor materials in negatively and positively dopes crystal layers in a variety of structural configurations. Mainly segregated into bi-polar and field effect types.

Tube Amplifier
An audio amplifier using vacuum tubes in its gain stages.

USB
USB stands for Universal Serial Bus and is a standardized interfact designed primarily for personal computers as a peripheral control interface, but may be used in other devices like gaming consoles and hand held portable devices. The USB standard is controlled by the USB Implementers Forum, Inc which is a consortium of industry players including Apple, HP, NEC, Intel, and Microsoft.

Warmth
A term meaning generally that the sound of something has more bass and less treble. Would be muffled or murky in the extreme.

Wireless
Wireless headphones replace the wire with an alternative method for getting the audio signal to the headphones. Most commonly this is done with analog modulation of 900MHz radio frequency transmission, but digital modulation of 900MHz RF, Bluetooth, KLEER, and infra-red systems are also available.

Sizzly
See Sibilant. Also, too much highs on cymbals.

Slow
poorer reproduction of rapid transients which decreases the sense of realism and "snap". Generally this means less of an ability to reproduce subtleties in sound. This is often a tradeoff when buying extreme bass headphones. Some say that slower sets seem to have a bigger soundstage but this may just be conjecture.

Smeared
Lacking detail; poor transient response, too much leakage between microphones; poorly focused images.

Smooth
Easy on the ears, not harsh. Flat frequency response, especially in the midrange. Lack of peaks and dips in the response.

Good low frequency transient response and detail.

Timbre
The tonal character of an instrument

Timing
A sense of precision in tempo.

Tinny
Narrowband, weak lows, peaky mids. The music sounds like it is coming through a telephone or tin can.

Tone
The sound of definite pitch.

Transient
The leading edge of a percussive sound. Good transient response makes the sound as a whole more live and realistic.

Transparent
Easy to hear into the music, detailed, clear, not muddy. Wide flat frequency response, sharp time response, very low distortion and noise. A hear through quality that is akin to clarity and reveals all aspects of detail.

Treble
The highest part of music and voice. See Highs. (Most often used when referring to the treble control on amplifiers).

Tubby
Having low frequency resonances as if you're singing in a bathtub. See bloated.

Upper Midrange (Upper Mids, High Mids)
The audio frequencies between 2 kHz and 6 kHz.

Veiled
Like a silk veil is over the speakers. Slight noise or distortion or slightly weak high frequencies. Loss of detail due to limited transparency.

Warm
Good bass, adequate low frequencies, adequate fundamentals relative to harmonics. Not thin. Also excessive bass or midbass. Also, pleasantly spacious, with adequate reverberation at low frequencies. Also see Rich, Round. Warm highs means sweet highs.

Wet
A reverberant sound, something with decay. Opposite of Dry.

Weighty
Good low frequency response below about 50 Hz. A sense of substance and underpinning produced by deep, controlled bass. Suggesting an object of great weight or power, like a diesel locomotive.

White (as in White Noise)
A mix of all frequencies with equal power for every hertz. This results in white noise sounding top heavy compared to pink noise. This is used to "burn in" headphones and also serves to mask other sounds if played at the same time. White noise is also prescribed as a solution to 'tinnitus' which is constant ringing in the ears due to its ability to mask sound. Electrical interference can sometimes create White Noise.

Woolly
Loose, ill-defined bass.

What You Need To Know About Microphones
There are a few things that consumers should be aware of before searching for a microphone. This section will touch on the most important characteristics so that the you can make a more informed choice.

Pickup Pattern
One of the more important things to know about a microphone is the area around the microphone that it will "pick up" versus the area it will ignore. Some pick up sound from all angles, others favor sound from just one angle---the front for example.These directional characteristics are classified as Omnidirectional, Bidirectional, Unidirectional or Cardioid. Just as a frequency graph will provide a useful indication of the microphones frequency response, a "polar" chart will provide a useful visual indication of a microphone's directional characteristic. A polar chart is if you are looking down on the mic and seeing what "pattern" there is to the sound it will accept.

  • Omnidirectional Microphone Pattern


    An Omnidirectional pattern or "Omni" mic will pick up sound equally well from all directions above and below, front and back. Omnidirectional microphones usually have a very flat response. This is ideal when you want to record everything in the room or you do not want the sound to change with location of the source. The most common application for an Omni is those "on location" TV interviews you see on the news. They are very useful where relatively inexperienced people are talking into and using the mic. Since the sound is picked up equally in all directions, you do not need to point the mic at one thing to "hear" it. There is no proximity effect with an Omni so you do not have bass boost changing the sound of the source.The Omni mic is not commonly used in live sound or recording for the same reason it works in TV news---it hears everything. You have no option of avoiding unwanted sounds and isolating the sound you actually want. If you are trying to record a single drum of a drum set, it cannot be done with an Omni. You need a mic that will isolate just the drum you want from the set of many drums.In live sound, an Omnidirectional microphone is often a bad choice because it will pick up various reflections of the sound you want from nearby walls, floors, ceilings, etc. An Omni can produce a very hollow sound on a mic stand on stage, where the sound from a singer hits the floor and bounces back up into the same mic they are singing into, canceling some of the sound you want. In live sound applications, you are less likely to use an Omni because you have a much greater risk of feedback when the mic picks up the sound from the speakers as well as the vocals! Omnis are most often seen as condensers in the recording of orchestras in excellent sounding rooms.

    Bi-Directional Pattern


    Bi-directional pattern, also called a figure eight pattern, is most common with ribbon microphones which are inherently "front and back" mics. Some studio condenser mics still offer figure eight patterns. In the early days of radio, it was used for capturing the performer and a live audience simultaneously, or two people sitting facing each other at table. Not useful for live sound, this pattern is most useful in advanced recording techniques called Mid/Side. There is no proximity effect with a bi-directional microphone.

    Cardioid or Unidirectional Pattern


    A Cardioid microphone is a microphone that picks up mostly from the front. Its pattern looks like a heart on a polar response chart, hence the name cardioid. The cardioid mic will focus its pick up pattern on things that arrive at the front of the mic, so you can point it at the sound you want and away from sound you don't want. This is the most popular pattern for live sound (it ignores the floor monitors and out front PA system) for it has greater "gain before feedback". This pattern allows you to eliminate the problems encountered with the Omni pattern because it can be pointed away from sounds you do not want. It is also the most important microphone for recording, for a user can focus the mic on just the instrument desired. It can also make a recording in a bad room better, because it "hears" less of the room and more of what is right in front of it.Cardioids all have some form of proximity effect, which is an unavoidable by-product of eliminating sound from the rear. With careful application, this proximity effect can be used to your advantage.

    Super Cardioid or HyperCardioid Pattern


    The Super and Hyper Cardioid pick up patterns have higher directionality and rejection of sound coming from the sides than Cardioids, but slightly more pick up of bass from the rear. They are very useful in isolating the desired sounds from the front and rejecting unwanted and ambient sounds from the rear and side. The caveat here is that the "acceptance angle" or pick up area is very small and the performer must stay directly "on axis" or directly in front of the mic to be picked up. Side to side movements can put a performer in and out of the pattern very quickly and cause significant problems for the sound system operator. The pattern is most useful in stable, non moving sources for live sound.

    Specialty Patterns


    The Shotgun mic is a very hyper cardioid that has a very narrow pattern but has greater "reach", so the source can be further away than a normal cardioid or hyper cardioid. This mic can work a source that's 3 feet way. This mic is best used on location video, TV talk shows hung from a big boom and location movie work. It is used primarily to isolate sound in higher noise (high ambient noise) environments. The Parabolic mic has a very narrow, pencil like far reaching pattern and is best applied on football field sidelines where the microphone will be very distant from the sound source (the football players). This mic works on sources over 30 feet way. This mic has very poor sound quality for you are using a dish to focus the sound. It is not used for any high fidelity applications.

Does It Have A Headphone Jack
This applies to USB microphones only. If you wish to hear your own voice through headphones or speakers without lag on a usb mic then you want a microphone with a 3.5mm headphone jack. While entirely possible to do do this with a usb headphone without such a jack there is typically lag delay between when speech is produced and when you hear it on the headphones. this can throw off recording if trying to sing in time with played audio or may result in a speech jamming effect which can result in you stuttering so software will need to be used to introduce a "delay" into the sound you are hearding to match up with the hardware delay of the sound traveling from the usb mic through your computer and out your headphones (or speakers).

Connection
The most common connection type for quality microphones in the consumer pro audio market is usb which allows its use on most devices. be aware that most commercial pro audio (outside the consumer sector) uses XLR connectors which requires special equipment if you mean to use them with personal computers. This is typically either a phantom power source or audio interface device. Cheaper microphones and headset add on microphones typically have 3.5mm input analog input meant for using with your soundcard/pc input via the microphone input jack.

Type of Microphone
There are various different styles of microphones which each have their own unique sound as well as being more suitable for certain tasks and less suitable for others. In this section i will touch mainly on condenser microphones since this is the type of microphone most commonly sought for computer use but will briefly touch on some of the other styles.

Types of Headphones
There are many different styles of headphones which are suitable for a variety of uses. Often a certain style may shine in a few given categories however may be subpar in others. Some general things to keep in mind when choosing headphones are:

-Portability (does it need to travel? if it does then either folding designs or a smaller lighter pair of headphones may be preferable)
-Durability (does it need to withstand abnormal levels of abuse such as when traveling or having multiple users?)
-Cost (is it within budget? keep in mind that you often get what you pay for and better sounding headphones are more expensive)
-Sound quality (certain headphones are better with certain sound signatures. you need to pick one which is suitable to your needs)
-Connection type (while most headphones are 3.5mm there are variations which use 6.3 or multiple 3.5mm jacks)
-Stereo or surround sound (is better sound more important or surround sound? keep in mind virtual surround sound as well)
-Amplification (does the headphone need amplification? do you have such equipment. this could be a soundcard or an external amp)

In-Ear Headphones

This style of headphone is characterized by being small, lightweight and sitting inside the ear. due to the size, weight and fit they are excellent for traveling or any rigorous activities or exercising.

  • Earbuds

    Earbuds sit in the outer ear and create a loose seal at best. Typically, they provide low isolation from outside noise and need to be turned up louder in noisy environments. In addition to low isolation, the lack of a seal typically results in lower quantity of bass, especially deep bass, compared to other types of headphones. The one-size-fits-all nature of ear buds will result in many users having trouble achieving the best comfort, sound quality, and/or secure fit with earbuds.

    Also, due to being constructed out of hard plastic some users may experience discomfort if the earbuds are used for extended periods of time. slip on foam pads may be used to help allieviate the discomfort and to offer a washable hygenic cover but this may adversely affect fit on some earbud designs.

    Since earbuds only sit on the outter ear they typically are slightly more hygenic and require less cleaning than other styles of in-ear headphones.

    Earbuds are typically the cheapest option available for in-ear headphones and also offer the least quality level of sound.

    Canalphones

    Canalphones are characterized by having eartips similar to IEMs but shorter in length and sitting inside the ends of your ear canals. they form a slight seal which while better than earbuds is not as good as IEMs. They form the middleground between the two styles of in-ear headphones and offer decent bass and some noise isolation.

    Since they use soft tips which do not sit deep in the ear canal (and with the availability of different tips for different sized ears) these are the most comfortable style of in-ear headphone.

    Due to sitting inside the ear canal they may accumulate some earwax and debris similar to IEMs so may require frequent cleaning.

    Canalphones typically hold the middleground in terms of both price and performance.

    In-Ear Monitors (IEMs)

    In-ear monitors are characterized by having ear tips that form a seal with the ear canal. IEM performance is heavily dependent upon ear tips which determine sound quality, comfort, isolation, and fit security. Due to having a tight seal IEMs typically offer more substantial bass than other designs as well as slight noise isolation.

    Due to the availability of different soft tip styles and materials IEMs can be adjusted to fit many ear canal shapes to improve comfort. However, some people may find them uncomfortable since they sit fairly deep in the ear canal.

    Since IEMs sit deep in the ear canal they may require regular cleaning as they may accumulate earwax and debris over time.

    IEMs are typically the most expensive option available however they also offer the best quality of sound.

    Around-The-Ear


    Some earbuds and canalphones have a design which encircles the outside of the ear which helps to keep them firmly in place during rigorous exercise or other physical activity. there are also models which feature a band which wraps around the rear of the head connecting both halves to make them one piece.

    Otherwise, these models are the same as the base styles.

On-Ear Headphones

These use larger drivers than earbuds, canalphones and IEM's and instead of sitting in your ear they sit on the outside of the ear instead. Generally they use a more narrow headband than full sized headphones which goes over or behind the head phone while some use a small clip which attaches to each earpiece and holds it to the ear. Some are of foldable design for travel.

Since they sit on the outside of the ear they are hygenic and do not require frequent cleaning. By sitting on the outside of the ear instead of enclosing it like full sized headphones they are also much cooler to wear and should not overheat your ears. This comes at a price however and certain designs may be prone to falling off due to sudden head movement unless they have an ear clip.

They come in both open (more airy sound with larger soundstage) and closed (more of a seal for better sound isolation and heavier bass response) designs however can not generate the seal that full sized over-ear closed headphones or in-ear IEMS can manage so may be outclassed in those areas.

  • Open-Back

    These have an design which prevents them from sealing on the ear (typically holes behind the driver) so typically generate a more airy sound (wider soundstage) than closed designs. Since soundwaves can escape they can be more crisp and clear than closed-back designs however also typically lack great bass response.

    Closed Back

    Closed headphones are designed to form a seal on your ear. This allows for stronger bass response as well as sound isolation however they might not be as crisp and clear sounding and often have a much smaller soundstage than open designs. also, since air cannot freely circulate they tend to be hotter than open designs however on-ear models are typically much cooler than over-ear. While certainly better than other designs they still fail to achieve the seal of in ear IEMs as well as full sized closed-back headphones.

    Lightweight

    Lightweight headphones feature a thin frame and true to their name are typically so light you may forget you are wearing headphones. The issue with such a frame is that they are more succeptible to damage or breakage as well as falling off due to sudden movement due to a low clamping force. Sound quality is typically mediocre at best since often only cheaper headphones are of this design.

    Sport Models

    Sport models are characterized by having ear clips and may or may not have a headband. These models models resist falling off the ear however are typically of open design (not open back) since they do not generate a good seal on the ear. This is good since it means less sweating due to the headphones however it also means that you will not get as much bass response or sound isolation as you would with closed design headphones.

Over-Ear Headphones

This style of headphone fully encloses the ears inside the earcups and typically has a much larger and thicker frame as well as having significantly more padding in both the headband and earcups. Due to the weight and size they are not a good choice for listening while performance active tasks as they are cumbersome and may fall off however they are unparalleled when it comes to stationary listening.

  • Open-Back

    Designs which allow airflow in and out of the headphones are called open-back. typically they have either a mesh panel or pattern of holes or slots behind the driver to allow airflow to escape which also allows soundwaves to escape. this results in a headset which is cooler to wear despite enclosing your ear and which has an open and airy sound. This is called having a wide soundstage. a good analogy is that an open pair of headphones is like listening to a concert outside in a park where the sound has an airy/ambient quality to it. Since they allow airflow and soundwaves to escape others nearby might also hear what you are listening to if the volume is too loud. likewise it is also possible to hear ambient sounds around you despite wearing headphones. This makes them a good choice in rooms where you are alone or when you need to be able to hear what is around you.

    Semi-Open-Back

    Designs which are not quite closed-back and not quite open-back fall into this category. They are a good choice for individuals looking for headphones which are slightly more bassy then open designs but still retain a decent soundstage and are slightly cooler to wear then fully closed headphone designs. It is also possible to sometimes modify either open or closed headphones into this style to change their sound signature.

    Closed Back

    Fully enclosed and sealed designs are called closed-back. They do not allow airflow or soundwaves to escape and do not have any holes or venting behind the drivers. This results in thicker, deeper bass as well as passive sound isolation. Closed-design headphones can be described as listening to a concert inside a small club where the sound is more direct and in-your-face where some minute details are lost however bass is also more intense. This is also described as having a small soundstage. It is much harder to hear ambient noise around you and others also are not easily able to hear what you are listening to. This makes them a good choice for use around crowds of people as well as when you want to block out the outside world.

    Standard headphones

    These are your run of the mill consumer grade headphones. They have more budget friendly pricing schemes however also do not have the sound quality of either dj or studio type headphones. Typically they do not require any special amplification and work in most devices.

    For individuals on a budget who want average, acceptable but not great sound quality this style of headphones delivers.

    DJ Headphones

    These feature better quality sound than standard headphones however since they are meant to be used in a club by the dj feature high sound isolation due to a closed design, very loud output to overcome ambient noise as well as high levels of bass at the expense of sound quality. They might also have features such as swivels built in to the earcups or other features which may be convenient. Designs are often not as comfortable as studio type headphones however this is not always true.

    Such designs are perfect for individuals who love thick deep levels of sub bass at the expense of muddier sound and enjoy being isolated from the outside world.

    Studio Headphones

    This class of headphones can be divided into two subclasses. Headphones meant for the studio which typically feature a flat eq and high accuracy for musical production but may not be as enjoyable for casual listening and Audiophile headphones do not feature a flat eq and are generally more enjoyable for casual listeners. This class of headphones is generally comfortable and is available in open, closed or semi-open designs.

    For audiophiles and users wanting comfortable headphones and quality sound this style of headphones is ideal.

How to add a boom mic to any headphones
original credit to goes to demux4555 at imgurl for this d.i.y. [click]

as an alternative to the do-it-yourself modification below you may also purchase the antlion modmic for a slightly cleaner appearance (no zip ties needed.

Detatcheable 3.5mm Headset Microphone

This is the detachable microphone from the inexpensive Creative Fatal1ty Gaming headset. It's a noise canceling condenser mic that has a 3.5mm mini-jack fitted directly onto the arm itself, and should work perfectly for my mod. I've seen many other cheap headsets with almost identical (removable) microphones that should work just as well, but I decided on this one from Creative to make sure the audio quality would be good.

Microphone Tip Detail

Take a mental note of what side of the mic that should face your mouth. Noise cancelling microphones often have holes or openings on both sides of the microphone unit. This mic has a "splash" filter fitted in the openings where the mic is located, so it's fairly easy to see.

Plug Modification Side View

This microphone arm's plug has a small rubber guide that has to be removed with a scalpel or sharp knife. Luckily this plug already has a flat side, so I won't have to remove more material to make it fit.

Plug Modification End View

This is what the plug's profile has to look like to fit properly; one side has to be flat.

3.5mm Cable Attachment

I'm using a 3 meter long 3.5mm (mini-jack) female-to-male extension cable. The female connector is fastened to the headset using very small cable ties.

Mic Attached

The mini-jack male plug on the microphone arm fits directly into the connector.

Note On Zip Ties

Notice how the cable ties' lock case are positioned. There is no contact with the plastic case beneath, and should not leave marks from wear and tear over time. On this photo you can also see why one side of the plug has to be flat to avoid pulling the connector up when the mini-jack plug is inserted.

Finished Mod

This is what the beyerdynamic DT 770 Pro looks like when the mic is attached. Works like a charm, and the audio quality from the mic is like any factory mounted microphone found on gaming headsets.

Finished Mod Close-Up

A closer look at the finished mod. This solution is rock solid, and I'm quite sure it will last a long time without having to refit the connector. If I want to remove the mod at a later point, I just cut the cable ties, and the headphones are back to their original state - with no traces of the mod.

Finished Mod With Mic Detatched

If I want to use the headphones for music listening - without a microphone in front of my face - I'll just unplug the mic.

Sennheiser HD598 $180,

Whathifi HD598 Review [click]
Reviewed.com HD598 Review [click]

A favorite among gamers, this is the improved version of the hd595. It's extremely wide soundstage and positional accuracy make it excellent for both music listeners who prefer a more neutral sound profile and for gamers looking to upgrade from gaming headsets. They pair very well with virtual surround.

Style: over-the-ear
Type: open
DAC/Amp: not required, but headphones respond well to it.
Best for: gaming, music lovers who prefer a neutral non bass/treble heavy sound
Pros: large soundstage, great positional accuracy, detailed, balanced sound, good clarity, comfortable (but heavy clamping)
Cons: low bass response, sound profile is not as fun as others, some may find them less immersive due to low bass in games

and as for the code..
