Solar-Powered Headphones - The Bluetooth Solar Headphones Harness Sun Power When You're Outside (TrendHunter.com)

Technology and heat often leads to devices overheating and subsequently losing their ability to work, so the Bluetooth Solar Headphones aim to change this with a design that is sun-friendly. The headphones are implemented with a series of solar cells on the incorporated neck piece in order to soak up energy from the UV rays that hit it when you're out and about during the day. This means you would never technically need to charge the wireless headphones if you spend enough time in the sun.
