What type of headset is this? It may need a firmware update:

Once you do that, you'll want to rebuild the bluetooth stack. Remove the device from your phone, power off, power back on, re-pair the bluetooth. That will rebuild the bluetooth stack and is best practice after updating firmware. (I spend A LOT of time on PLT's forums).

Also, I don't recommend the M series. They are the stupid cousin of the Voyager series.

Sadly my BT isn't any of those. It's the M55 - Just a simple unit.

Oh, I'm sorry...
