I've been searching for a pair of headphones to use for extended gaming sessions (I. E. Multiple hours at a time) that are comfortable and don't give me a headache. I've tried the following sets: Vmoda Crossfade LP2, Beyerdynamic DT770 pro, Sony mdr1a, akg k7xx and the famed Philip sh9500s. The sh9500s has been the best regarding comfort for length of time tends to hurt and give me a headache around an hour of use or less. I'm really frustrated with not being able to be comfortable while playing. Do you have any suggestions on how I can remedy this issue? The qualities of importance in order are: 1) Comfort 2) Soundstage 3) Required amplification - currently do not have an amp but would consider getting one if the headphones provided the comfort level I'm looking for. I have a fairly large head with the commensurate size ears. Thanks in advance!
