Sony DR-BT 22iK - headphones in stock at Asda (Swindon Orbital) - were at least 20 sets on the shelf around 2pm today.
I was gutted to miss out on these a few weeks ago, and really pleased to happen accross them this afternoon.
Similar headphones (neckband style though) at Argos - half price at the moment £39.09
Same unit at Amazon £51.99 - link: http://www.amazon.co.uk/Sony-DR-BT22IK-Bluetooth-iPod-Headphones/dp/B0013LL3R4/ref=sr_1_1?ie=UTF8&s=electronics&qid=1234020342&sr=8-1
Edit - Apologies for re-posting, but in one of the earlier threads someone posted that they contacted ASDA sand they stated they had no more stock in the country, and wouldn't be stocking them again. Hopefully this post has helped those who missed out lasrt time, and didn't bookmark the old deal where I guess I could've noted that there was a shelf full in my local store.
Anyway - the sound quality sounds fine to me (I am no audiophile though), they are comfortable to wear (the headband is definately too bulky to go under my cycling helmet - so probably won't work for the snowboarder in one of the early replies.). They can pair with up to 8 or 9 devices, and will work as a handsfree for your mobile.
