Hi, about 5 months ago, I bought a Plantronics Explorer 210 bluetooth earpiece, and paired it up with my HTC Desire. It worked once, but then the Explorer totally died on me, no light, nothing. I figured it was just a faulty earpiece, so went to the store to exchange for another one. Unfortunately, it happened again, worked once but then stopped working. Does anyone know why this is caused? I had charged like the manual told me to. Any help would be great, because these cost $50, and I cannot return them. Thanks in advance!
