I have a set of the Plantronics 903 backbeat Bluetooth headphones. The Bluetooth connectivity is bad, it's totally unreliable outdoors, constant drops. Inside it's better connectivity. The ear things are difficult to use, but I will say the sound quality is great, if you can get use to the ear things it delivers great music sound. The Bluetooth telephone part of the device is bad. Everyone I talk with says they can't hear me. Battery life is great, and the headset folds up into a small pouch. Play/pause skip forward, skip backward and volume controls really suck bigtime, very awkward to use, so bad I was constantly taking out my phone to manage what should be done on the fly. They are very light weight though and wrap around the back of your head ok. They were low cost , under $50 if I remember correctly.
