Levi Strauss is to introduce a new range of 'iPod jeans' featuring built-in headphones, joystick and docking cradle.

The RedWire DLX range is designed for men and women, and has a special side pocket with a white leather patch to store an iPod.

A four-way joystick on the watch pocket allows the user to play/pause, track forward/back and adjust the volume without removing the player.

Retractable headphones have been built in, as has a docking cradle that allows users to look at their iPod screen and control it via the jeans.

"In designing the jeans we considered both function and fashion. The result is a uniquely functional, yet stylish, great fitting jean," said Robert Hanson, Levi's US brand president.

The company describes the jeans as "machine washable once the iPod has been removed". They will be available by the end of the year, and are expected to cost in the region of $200 a pair.
