I was in B&M today and spotted these.
As I was after a tempoary pair till christmas (till I get some Sennhesier's) I decided they seemed like a decent deal.
Cheapest place direct from a retailer seems to be Amazon at £9.32.
Qualitywise they're bloody good for a £4 headset.
Decent sound quality - it is a little too bassy and the sound leaks like crap but hell who cares?
Microphone is also very good and is very sensitive which is great.
Specs off Amazon.
* Lightweight neckband multimedia headset with microphone
* Superior sound performance and clear voice transaction
* Lightweight and fully adjustable
* wired connection
