Yesterday I purchased a Plantronics Voyager 855 stereo Bluetooth headset, expecting that I'd be able to use it with my N800, which is running OS 2008 2.2007.51-3.

It sort of works, but the sound when playing MP3s is like listening to a scratchy phonograph record through a tin can and string. It's very tinny, with clipping and with constant scratchy noise. The same MP3 sounds great through the N800's speakers.

I thought the headset might be bad, but I tried it with a PC running Windows, and playing the same MP3 through the headset sounded fine.

Is the Bluetooth in my N800 defective? Or is this not expected to work? I thought it would either work fine or not at all, and was very surprised when it worked badly.
