IWOOT is claiming to have had their socks blown off by the Spring Speaker, a compact offering designed for MP3 players with two speakers that expands, concertina-style.

Using similar principles to the X-Mini Minimax that we looked at earlier this month, the speaker works in the closed position, but when you open it up apparently you really hear the difference.

With a USB rechargeable battery, the Spring Speaker is on sale now for £17.99.
