Adidas' new solar-powered headphones can also be charged by your bedroom light

Rain or shine, a new pair of solar-powered wireless headphones from Adidas have you covered. The athletic brand has teamed up with Zound Industries to make the Adidas RPT-02 SOL in-ear headphones, which can be charged with natural or artificial light. We were pleasantly surprised by the RPT-01 previously released by Adidas, which offers 40 hours of wireless playtime. The new line has an almost identical design but promises double the playback time - 80 hours - not to mention the ability to charge any time of the day. It is also made of a combination of recycled plastic and nylon.

The headband of the RPT-02 SOL is made of a highly flexible light cell material by Swedish solar technology company Exeger called Powerfoyle. The solar cell material can be screen printed onto plastic, allowing for a wide variety of applications, from walls to cars to consumer electronics. Unlike older types of solar cells which require a strong, constant source of natural light, Powerfoyle can charge in a variety of lighting conditions. Other companies have made solar-powered headphones before, so the RPT-02 isn't the first with this feature, but they're still relatively rare.

The RPT-02 is not waterproof, but is IPX4 rated. So it can handle the sweat and splashes of a nearby ocean or lake. The headphones have built-in controls for changing songs or volume, and there's also an indicator that helps find the best light for charging. And if all else fails, it includes a USB-C port. The RPT-02 SOL costs $229 and will be available for purchase online on August 23.
