... That's my third PX-100 in 8 years. As I have already mentioned, the sound for the price is unbeaten. Deep bass, loose-lofty heights, even a very natural sound event which fascinates me again and again. The only thing I regurgitates sour again, this is something thin, not replaceable handset cord! At SENNHEISER: Please ... make it last a jack as the HD 598 to the earpiece, then the cable would be exchanged ...!
