Seend 3 of these in the Leeds branch of HMV. It's £17.99 online.
Bearing in mind the transmitter on it's own is £14.99, £10 for all three is (in my opinion) a bargain.
A great gift pack for the iPod/MP3 user compiling of 3 key accessories which gives protective variety to your iPod as well as Portable Speakers and an FM Transmitter allowing you to listen to your tunes wherever you are!
The pack contains: 3 Universal MP3 Protective Socks - Set of three stylish elasticated socks designed to hold, store & protect your MP3 player.
Portable Speakers - The compact, foldable design and superior sound quality make these speakers an essential iPod accessory.
In Car FM Transmitter - FM Transmitter for in-car use. All your tunes will be played off the MP3 player through your car stereo.
