the logitech is $60, the sennheiser is $300. how can you possibly compare the two?
yes, there is going to be a rather large difference in quality of sound (although yes the pc363d is also overpriced for what it gives you).
midway between the two in price you could pair the hd558 or hd598 up with a microphone (desk mic like the snowball, atr2500 or boom mic like the modmic) and have the best of both worlds.
if you want anything more specific you will need to give some more thought to what you really want. are you looking for sub$100 and the best you can get for that budget? are you looking for the best sound under $200? are you looking for headset options only? etcetera. bouncing from $60-300 is not going to give you any sort of...
