Listening to music can be a drain on your smartphone or iPod battery, and stopping to charge up restricts your mobility. But with the OnBeat solar headphones, you can listen to music and watch videos on your phone or tablet continuously without stopping to recharge. The headphones are wrapped with a flexible solar panel that generates energy whenever you’re out in the sun.
The solar panel that wraps around the top of the OnBeat headphones feeds into a rechargeable battery that can be used to charge mobile gadgets. The solar cell has a surface area of 55cm3 with a charge capacity of approximately 0.55W, according to the OnBeat team, but it’s unclear how much energy it can produce. As Tech Crunch points out, because the solar panel is curved, it won’t receive full exposure to the sun at once, which might hurt its energy generating capacity.
OnBeat’s founders began creating a prototype for the solar-powered headphones about a year ago, and they have since refined the design. The company recently launched a Kickstarter fundraising campaign with a goal of raising £200,000, which will be used to begin manufacturing the first 2,500 sets of headphones.
