Was in my local Tesco store in the phone section browsing through the bluetooth headsets and saw this going. Was originally £39.99 then down to £19.99 and now only £4.97.
Has 9 hours of talk time when charged, 12 days standby, volume control and voice dialling. The only thing is though it's aimed at ladies, as you can see by the design on it in the pic, but picked one up as the missus can use if it she's driving, and I can nab it if I'm gaming online :)
Comes with charger and cradle. The charger can have the pin changed to either 3 pin or 2 pin for use abroad too.
Seems to be instore only as it's not on the Tesco direct site.
