Best Bluetooth headset for O2 Atom

[roytarun]

I want to buy a Bluetooth headset for my O2 Atom, can you suggest which one should I consider from the following

. Sony Ericsson HBH-DS970 Bluetooth Stereo Headset
. Jabra BT620s Bluetooth Stereo Headset
. Motorola HT820 Bluetooth Stereo Headset

Also, if any one from Bombay, having Bluetooth headset can give there comments on the sound clarity

Roy
