The original Backbeat Pro headphones. The battery needs replacing but still works wired (cable not included). I have purchased a zip up replacement headband cover and the ear cushions have come off and wre peeling could do with replacing. These are the best headphones I have ever heard reluctant to sell but don't have the time to repair. I have been lucky enough to test many top of the range much more expensive headphones such Sony, Parrot Zik and these are by far my fav, heavy natural bass and overall clarity. Hopefully someone can restore them to their former glory
