Which Bluetooh Headsets Work with Spotify and HTC One?

[intgom]

Hi All. I am canvassing the readers of this board in a bid to work out just how wide my problem is. I have a new HTC One with a new HTC Bluetooth Headset but the combined play/pause button does not work with Spotify (or Rdio for that matter). Is there anyone out there who has a Bluetooth headset AND an HTC One? If so, which headset are you using and do you have this problem? Many thanks in advance for any and all feedback. Kind regards.
