Have been fiddling with Bluetooth and have now got it going on my PCLOS box talking to my Motorola RAZR.

My question may be off topic?? - I have purchased a Bluetooth headset (everE T909S) to use with the RAZR. There is a persistent hum in the left ear piece that can even be heard over quiet music. Occasionally it is also heard on the right side but only very briefly.

Any ideas - do I have a fault somewhere?
