Was a spontaneous purchase due to the high-resolution Amazon advertising on my Kindle Fire. But I'm far from being disappointed. Had previously also the Apple headset the same price range in use, but the sound of the Amazon headset is better by a mile, and the buttons function. The only unusual event: When a call it does not ring in the headset, but on the phone. (Accept call, micro, hang up) The rest regarding. Telephony works again. Nevertheless, for me no bad buy.
