The main quality of this big headphones listening comfort and port; plugged into an amplifier, no need to raise the volume, the sound seems natural, never aggressive, even if it may seem to miss some treble-out. It may sound a bit dull if you're accustomed to headphones that seem to always be in loudness mode, that is to say, emphasizing bass and treble, but when listening to a recent film, with good sound quality, the impression of relief and presence (including voice) is a treat, even at very reasonable level, in addition, no earache! The advantage of the long cable is you can wear it to watch his TV. In addition, this cable can detach headphones, which avoids damaging if it is pulled by mistake. Minor complaint: the cabinet within which foamed the continent does not have a closing flap and throat containing the cable could be a little larger. A book for home use and low noise (it does not isolate outside noise).
