The Helios headphone, created by French start-up Exod, are looking to raise £50,000 by Christmas Day 2014.

Powered by a solar film atop the headset, one hour of sunlight provides 30 minutes of music playback, while a full charge lasts 15 hours.

Named after the Greek god of the sun, the device will use Bluetooth 4.0 to connect to smartphones for phone calls and music playback.

Product manager Steve Zetro Souza said: “Wireless technology brings great comfort of mobility and freedom. Unfortunately, like any other mobile technology, it craves large amounts of energy. 

“We wanted to associate ecology with technology in order to charge these headphones with free and natural energy.

“We have spent the better part of three years studying the design and technology in order to create a beautiful product that combines elegance and quality.

Eco-minded tech-heads can bag themselves a apair of Helios headphones with a pledge of £100 or more.

The Kickstarter campaign is symptomatic of the growing prominence of renewable energy in personal electronics. Last week Apple stores announced they would be selling a hydrogen powered portable phone charger.
