Just went into Gower St London Fopp store and picked up some Nike Motion Sport Headphones for £3. The next cheapest I could find online was £19.99 from the Co-op electrical store. Most other prices have these cans priced at £30. There were two left on the shelf in Gower St at about 1700 on Sunday 10th.
Worth a punt at £3, and sounds remarkable for the price.
