Headfunk has unveiled a portable music player case that has a built-in speaker in one.

Connect the Headfunk Sidekick speaker case to an iPod, MP3 player or music phone via the 3.5mm jack cable that comes bundled with the device, then slip your portable music player into the case and you can enjoy content stored on the player through the 30mm speaker.

Measuring 100x180x45mm, the Headfunk speaker bag is made from polyurethane and will protect your portable music player from damage. It also features a karabiner clip so you can attach the speaker bag to your belt or bag.

Available in pink, green or blue camouflage design, the Headfunk Sidekick is available now priced at £24.99.
