My Advantalk VFU-BTHS-03 work great with my Nokia N95 and N93i. But on my N900 it struggle to providing a clear sound. N900 seem to have a little miss communicate with the bluetooth headset.

I have to tweak it a little to make it work for a temporary period. Hold the volume key (-) on the bluetooth headset until the N900 decides to use the speaker mode. Then switch it back to headset and voila sound is clear again. But once the device is on Idle and the N900 just go on to the battery save mode, it just back to the same old problem again lol.

This is a must fix problem on N900
