The Magneat is a small button/yo-yo like two piece unit that winds iPod and other MP3 headphone wires to keep them from tangling. It uses a magnet to fasten the gadget on clothing. Separate the rear unit from the front unit by sliding them apart, then place the front unit on the outside of the garment, and the rear unit on the inside and the two pieces will attach together. The Magneat comes in various colours and patterns.
