Found these accidentally, while looking for other bluetooth headphones.
Temporarily out of stock, but still lets you order.
No idea if these are any good or not, but worth a go at £17. I've ordered a couple. :D
Compatible with Bluetooth enabled Smartphones, tablets and laptops
6 hour battery
Best thing about this is that you can connect any headphones to the bluetooth unit.
Hardly any retailers selling this now. Next cheapest is £60 on Ebay.
Did a quick search on HUKD and they've been this price or there abouts before but over a year ago at 7dayshop.
*6 hour battery life in stand-by only. 2 hours battery life in use.
