If you see this acorn lying in the road then don’t assume there’s a hungry Squirrel nearby, because this nut’s actually an MP3 player.

The Acorn MP3 Player: nuts

The Acorn MP3 Player is described as being “fashionable and cute”, with users able to control the volume and track order using a single button. It also switches on automatically when you plug in your headphones.

It measures 40 x 38 x 38mm and has 1GB of storage. It takes around two hours to grow charge up the nutty device.

But if you’re looking for something a little more feminine, then how about the Barbie MP3 player? The gadget’s been designed by Mattel to celebrate the plastic princess’ 50th birthday this year.

Although it looks like just a mirror compact case, the MP3 player has both a lid-mounted mirror and a separate LCD screen for displaying track titles and the artist’s name. May we suggest Barbie Girl by Aqua?

It also has 2GB of on-board storage and an FM radio.

Mattel hasn’t confirmed a launch date or price for its Barbie MP3 player yet, but the Acorn MP3 Player is available now online for $21 (£16/€14). ®
