I have this headset a bit longer. As it pushes me something, the temples are a bit tight for my skull, I have tried many more. Sennheiser PC350, considerably more expensive but lousy bass response, retour. eDimensionel AudioFX, also more expensive, 5.1 sound, very loud, decent sound, but upholstered leatherette, ears heat up and you sweat after some time back. Medusa NX 5.1, also expensive, sound very good, also the Micro, but caused by the Soundverstärung with USB mass hum, so also back. to be continue .....
No matter what I do, I always come back to my HS 900th :)
A little tip, I have recently, the onboard sound (ADI) against a Auzentech Forte 7.1 swapped, you should not believe it, but the sound has to worlds improves particularly the location.
