I compare with bose qc-30. The models are similar in form factor and price. These bose were able to: turn off when idle, say the level of charge, say the number from which they call (though everything is in English). So: Sony can't do any of this. And yet, I took it in order to listen to music in the subway. There is no noise reduction (when compared with bose) in a noisy car, you have to greatly increase the volume, you can hear conversations nearby, announcements of stations. At bose, none of this is audible even if the music is turned off. Disappointed. Maybe it's just my copy?
