I have a Sony bluetooth headset (Stereo) that works just fine. It gives an audio signal if a call is coming in (but not the ringtone). If you are playing music, it cut's off as a call comes in and restarts as soon as you end the call.
I use a Jabra BT8040 headset and it works flawlessly with my Curve. It gets great reception for the phone and I can listen to the media player throughout the day with no problems.
Plus they are relatively inexpensive.
