Help Bluetooth Handsfree problem

[hysys]

I have Samsung HM1000 bluetooth handsfree. When i pair it with Wildfire S, during incoming call, I only get feeble beeps (which very difficult to hear in noisy as well as even in normal condition). Where as when i pair the handsfree with Nokia handset, I can even get a MP3 ringtone in the earpiece.
What could be the problem ? Any solution ?
HTC customer care asked me to soft reset & try again. But no luck.
Wildfire S has bluetooth 3.0 where as handsfree is bluetooth 2.1 +EDR.
HTC customer care says it should support.
