i couldnt stand it anymore! My pc350 headset just plain sounded like junk- i couldnt lie to myself anymore. but it uses the hd595 speaker a sennheiser rep said .... so it had to be a design issue. then it hit me- it sounds like a small headphone! but these are huge.
some quick disassembly:
notice the small enclosure around the speaker!!!!! putting this against my ear with the earpad revealed that it sounds the same without the large outer cup. the enclosure is glued in so i drilled 3 holes away from the speakers
and OMG! real bass! thumping bass if i turn up the eq on the bass side. now it responds to an amp. sounds very much like an hd280 with more bass.
(i also put one cottonball in the large outer cup for damping after a little experimenting). it should have been this way to begin with. i cant beleive sennheiser let this thing out the door the way it sounds
update 7/20/09 several peeps from different forums -here, hardforum, and overclockers, have tried this mod and gotten me into these again. with the better amping i own since doing this (i now have a little dot 3), i can safely say that the bass here easily beats an hd280 and harx700 and approaches a denon ahd2000 and senn hd265 in bass power and ability. soundstage is nice and wide for a closed can and it responds very well to both dolby headphone and openal games. truly what a higher price sennheiser headset should be!
be sure to check the next few pages for better photos from other modders
also take it slow. start with one hole and work your way up. the more holes the more bass boom but you want a nice balance
