Question USB charge BT Stereo Headset

OK had enough of using the included usb wired headset and thinking of getting a BT one.
Don't want to have to take yet another charger on the road with me so want usb charge connector.

Have looked at Jabra BT620s as it is USB charge and can also be used as a USB wired pc headset

Any recommendations of mini USB charge BT stereo headsets and if they can also be used as a PC usb wired headset.

O2 Exec... Nice but we'll see...
