I have for years a SONY MDR-W24 headphones thrills me every time I use it, ie every day. It is extra light, not to feel his presence, his-ear earphones are compact and do not feel in the ears. The sound is excellent ,, deep bass, treble carved beautifully. I would be absolutely filled IF ........... wire is not hung wherever there was a projection. To me moo rage. So I looked if there is wireless; Well no! Sony has not had this good idea and left to BeeWi. Bluetooth headset Beewi is not as perfect but it is very honorable; It is almost as light, his ear a little more sensitive to the flag and her (lol!) Is nearly as thin. But no wire is a joy. His commands. are very discrete although very accessibles.L'ensemble is elegant. The fifth star, I do not give a hair closely: the sound has not even when the subtlety of Sony.
