Chunky headphones are the music accessory of the moment – and now one pair comes with an in-built solar panel which charges your mobile phone.
The headphones have a flexible solar cell which covers the headband and the energy generated is stored in two lithium-ion batteries in the two ear cups.
However they will only be available if developer Andrew Anderson and his partner get enough orders. They are raising funds for the project on crowd-funding website Kickstarter.
They need a minimum order of 2,500 sets of headphones and are looking to pull together £200,000. So far 183 backers have chipped in £14,211 with 26 days to go.
