I went through two of these headsets, after about 2 weeks, I would start getting low-battery beeps after an hour or so of standby.The headset would buzz to the person on the other end of the call, and I had to just dump it.Logitech support was helpful, particularly when I called them from the headset and they heard the buzzing. They sent the first replacement right away, I didn't bother with replacing the second unit.
