Techs & Trends

I have a samsung sgh-d600 and I am looking for a BT headset. My primary use for this headset is to stream mp3s from my phone. So sound quality is all I care about. The d600 supports a2dp so I can get stereo sound, just curious if anybody out there can share their experiences with BT headsets. Again, all I'm concerned with is sound quality.
I've considered:
Moto HT820
Jabra BT620s (doesn't come out til late April)
Plantronics 590a
Infinxx icombi 800
IOGear GBMH201
