A new pair of headphones which use solar panels to charge your mobile phone have launched on Kickstarter.
The OnBeat Solar Headphones are designed to be a new way to charge your mobile device while on the move.
They incorporate rechargeable batteries and a full headband solar panel to keep your phone or tablet topped up with power.
The headphones have now launched on the website Kickstarter, looking for £200,000 to develop full prototypes and go into production by early 2014.
Profiled on the BBC on Tuesday, the project's leader Andrew Anderson said he is still working to improve the headphones - and admitted his father had come up with the idea.
"It's really simple - you would think it had already been done," he said.
"You can buy solar chargers for phones but the thing is it's like you're carrying two phones around."
On the Kickstarter Anderson added:
"The solar cell has a surface area of 55cm3 with a charge capacity of approximately 0.55W. The energy is stored in two light-weight Lithium Ion batteries held within the two ear cups for a balanced weight and fit on the head. For those rainy days we have also developed the headphones to be able to be charged via USB directly from your computer or mains socket.
From the offset we not only wanted to develop a product to keep your devices going all day, but a product that would give you a superb sound from low range for bass, mid-range for precision DJ'ing and high range for vocal and acoustic excellence. The headphones also have an integrated remote for controlling the volume of the music in your ears."
So far the campaign has raised less than £10,000 by promising a number of rewards for early adopters, including a pair of the headphones and limited edition extras.
They admit there may be "complications", however ("Manufacturing a product is a complicated process, we have tried to consider every eventuality in order to get this product ready for manufacture...") but say they will work to keep the final product as close to the original design as possible.

Bowers & Wilkins P3
These headphones won <a href="http://www.t3.com/reviews/b-and-w-p3-review" target="_blank">T3's music gadget of the year award</a>, and if you try them out you'll see why. The sound is beautifully rendered, while the build quality and styling is pretty flawless. (£169)
RHA make great headphones right here in Britain, and while we were generally fans of their more-expensive 750i in-ear phones <a href="http://www.huffingtonpost.co.uk/2013/09/26/rha-m750i-review_n_3995780.html">we found them a bit heavy and 'brutalist' for our taste.</a> The <a href="http://www.amazon.co.uk/RHA-MA600i-Isolating-Headphone-microphone/dp/B00ELAM8M8/ref=sr_1_3?s=electronics&ie=UTF8&qid=1383836542&sr=1-3&keywords=rha">MA600i variants</a> are better overall. They're lighter, smaller, cheaper and still have great sound-quality with excellent noise isolation.
Sol Republic Tracks HD
Sol Republic's 'Tracks' headphones (£79.99) are solid, well-designed, powerful -- and totally overshadowed by the fact that they're <a href="http://www.huffingtonpost.co.uk/2013/02/15/sol-republic-tracks-v8-review_n_2695230.html" target="_blank">virtually unbreakable, and thus impossible to stop fiddling with.</a>
Bose QuietComfort 20i
These in-ear headphones are among the best we've ever tested - and you'd hope so, <a href="http://www.bose.co.uk/GB/en/home-and-personal-audio/headphones-and-headsets/acoustic-noise-cancelling-headphones/quietcomfort-20i-headphones/" target="_blank">because at £259 they aren't cheap</a>. What you get for your money is a combination of great, rich basic sound, brilliant noise-cancelling tech and the most comfortable fit you can find without involving a custom-made solution.
These unique headphones are not only designed by Philippe Starck, and as such gorgeous, but are also wireless, have touch controls on the ear piece and are NFC enabled - meaning you can transfer music to them with a single tap. They also know when you've taken them off, and automatically pause when you do. (£250)
Klipsch X7i Earphones
<a href="http://gdgt.com/klipsch/image/s4i/" target="_blank">These light-weight, durable and well-rounded earbuds</a> are a good step up from the basic Sennheiser CX 300 IIs, but they won't break the bank either at £149. The noise isolation alone is worth the price.
These headphones have won fans all around the world for one simple reason: for this price (£50) <a href="http://www.amazon.co.uk/AKG-K451-Foldable-Mini-Headset/dp/B005LBQ7BY/ref=sr_1_1?ie=UTF8&qid=1383837172&sr=8-1&keywords=akg+headphone" target="_blank">you can't do better</a>. They sound excellent, fold up neatly to stow away in a bag, come with a basic cable and a cable with a built-in three-button remote and won't leave you bereft if you lose or break them.
Marshal Major 50
These <a href="http://www.marshallheadphones.com/headphones/major/major-50-fx" target="_blank">limited-edition Marshall headphones</a> come with all the unique styling and sound engineering you'd expect for the amp masters, along with some extra design touches for good measure. They include gold-rimmed pads, inscriptions on the inside of the headband and a remote/microphone control on the cable. For £140 they aren't cheap - but there're no other headphones around with this kind of rock pedigree.
Jaybird Freedom Sprint
These resilient, water-resistant Bluetooth headphones are designed for exercise, and come with a set of neat ear-moulding foam inserts to keep them tightly in place when you're running. <a href="http://www.huffingtonpost.co.uk/2012/10/24/jaybird-freedom-sprint-headphones_n_2009106.html" target="_blank">For £105 it's hard to find a better pair of sport earbuds.</a>
