senn px100, Ie 8
The PX100 is nice, but there is a major issue with it - people sitting around will get annoyed because it doesnt shield the sound well from outside, so people around can hear the music as well
PX100 is open-aural design. It will not shield sound from coming out. Due to it's open-aural design, it gives superior sound with no loss in quality and no distortion at lower volumes.
