BeyerDynamic MMX300 or Sennheiser PC363D for gaming (mainly FPS)

pc363d, game zero, pc350se are all similar and related products from sennheiser. adg1 is a similar sounding headset from audiotechnica. mmx300 is based on a dt770 model from 2005.

all but the mmx are bass light with decent soundstages and more treble/mid focused. with a good amp the mmx should have a bit more bass but you may not be looking for that.

any of them will work though the adg1 based on the ad700x will have a wider soundstage. not everyone likes the headband though (love it or hate it scenario). game zero/363d are similar but one comes with a cheapo sound card. beyer mmx300 is just overpriced normally.

the game one isnt bad either (hd598) and instead of being as treb/mid focused its more neutral.

you could also go with separate headphones and mic and possibly either a soundcard or amp. depending on prices you can sometimes get the same exact thing (ad700x + mic in the case of the adg1 for example) for lower price while sometimes while at other times the headset is similar cost.

i think the most important thing here is what sound signature you want...
bass light - advantageous to fps gaming but not very exciting sounding
neutral - jack of all trades but a bit plain and boring to some
v-shaped - very exciting sounding but not as advantageous as bass light
bassy - enjoyable for bassheads but lacking for fps gaming.

i know the the ath-ag1 is the closed version of the ath-adg1 (a700x closed instead of ad700x open)

the adg1x and ag1x i would believe are just newer "improved" versions of that. they say that they redesigned the drivers but i cant imagine them giving up the bass light sound that made them so popular in the first place so i would guess they sound similar though you may want to see if that is the case. i havent heard much on them given that they are so new so could not tell you for sure.

given the cost at $300, its likely a rip off as the ad700x/a700x are $115 cans and you can get a good mic for $40 (modmic) which equate to about the same thing for only $155 (half the price) which leaves much room for a good soundcard. most of the other gaming headsets made from headphones are similarly overpriced except the game one from sennheiser which is just a bit higher than its headphone form.

for the money the audiotechnica ad lineup (mostly ad500x, ad700x, ad900x we are talking about here) is going to have the largest soundstage or in other words "depth" or "3d" sound. they are also mostly treble/mid focused and while they have some punch to bass its not very deep so they are often called very bass light or even bassless by some people which isnt completely true.

they are comfortable for some but some people do not like the 3dwing. as i said before its a love or hate it design. the people who love it feel its like the headphones are barely there while the ones who hate it say it digs in.

as i said before the adg1 is based on the open ad700x while the ag1 is based on the closed a700x. similar but given the soundstage is better on the open version that is considered the better choice and the closed version is only recommended for people who absolutely need a bit of isolation. i cannot say much about what changed on the newer version.. but it should be similar.

for fps gaming and a person seeking advantage (generally this means good 3d positioning, wide soundstage and good detail which means you can hear footsteps and such things easily) it is a good option.

as always there is no "best" headphone/headset as it depends on your preferences. for instance if you did not want a purely advantageous headset and wanted the sound to be a bit more "fun" sounding then a more neutral headphone might be up your alley. or if you wanted something purely fun then a v-shape might be up your alley.

an alternative to the sound signature of the ad series? perhaps the akg q701 but you would need a good amp. or, you could take a bit more bassy headphone (perhaps a neutral can like the hd558/hd598) and then EQ the bass down a bit. of course there are some lesser known headsets/headphones which will work as well although i'm not as familiar with them.

honestly the only really big thing the cheaper ad-series has going for it is that sound quality is decent and it has an unnaturally large soundstage which ends up being very suitable for games. this is why it ends up being recommended all the time.

hxc 1 & 2 are similar sounding. difference is that i believe they changed the mic on the second and the second has the option to come with a usb soundcard.

for someone who wants the most advantage:
ad700x + modmic OR ath-adg1

for someone that doesnt know what they want or wants something not too bass light but not too bassy:
hd558/hd598 + modmic OR game one

for someone that wants something fun sounding and can have an amplifier in budget:
dt990 + modmic + amp OR alternatively dt770 + modmic

but what about the hxc? for below $100 its not a bad choice for a headset (its based on the takstar pro 80 headphones) but if your budget is over $100 there are better things out there. its certainly better than the gaming headsets you see (razer, corsair, logitech, turtle beach) at least.

Hi, you can get the dt770 pro wich have a 250 ohm impendance which is good for csgo but if you want to go for MMX300 you should buy manufactured version with 600 ohm
