I have the same issue and it's really bothering me. It happens every time you brush against the play button on the right earphone, serious engineering flaw. I hate it playing all the time like that, don't know how much of a drain it is to batteries but it's very, very, annoying. If I had known it would have been such a annoying feature I'd never have bought the headset to begin with. I'm now looking for a way to disable the player from playing at all, not having any success though.
