I had bought this one a year ago worked great, it was nice being able to listen to the music on it. But it met an untimely death in the washer.  I recently bought a new one, however this one has several problems.
1.the vocalist keeps being activated most of the time even though i only hit the front button, this is an annoying feature that should be turned off as the android phones do all this now.
2.next problem is over half the time the front button does work it asks for a command but will not respond to it you have to try 4-5 times usually rebooting the headset before it will work.
3.many times the unit will disconnect from the phone when you press the front button.
4. the voice recognition on this new headset gets things wrong over 60% of the time.

the first one did not have these problems. try the Plantronics M20 Bluetooth Headset instead it is more reliable, but no music playback on it.
after contacting plantronics with the issues they finally sent me a new one lasted a month started same things, now will not sync with any phones don't waste your money the vocalyst ruins this headset all other plantronics I had were great. the M50 can stream try it.
