Sony Ericsson Stereo Bluetooth Headset HBH-DS220 @ Tesco (In-Store)

I've been looking to buy a bluetooth headset for the last few weeks and have just wandered into my local Tesco (Cannock) to find this Sony Ericsson kit with 75% off RRP.
The same unit sells on Amazon at £38.75.

Thought it was too good to miss, bought the 3 on display (make good xmas pressies)


FULL DESCRIPTION
Clip the lightweight pendant to your top where it can hang out of the way. The music and call handling keys remain close to hand. Leave your phone in your pocket or bag and listen to the music saved on it in high quality wireless stereo. Handle calls without touching your phone.
Never miss a call
Its called a stereo portable handsfree because its for more than listening. A microphone, call answer key and 3.5 mm jack to swap headphones are all built-in.
