A headset is always first a little disturbing. At first I chose for cable versions, but this is impractical. A Bluetooth version was battery-related nonsense.
Everything is different here. Here is a great solution was found on the part of my favorite Japanese Group. I had not at any time feel that the headset is annoying me or generated carrying pain, bruising or similar. For the money it bit my opinion nothing better.
In addition, and I think that much more important, the sound (subjective as everything) outstanding and meets every note. Rich clean music image with excellent expression of fat bass, which does not destroy the rest of the music but "soft" support.
Thanks Sony.
