Adidas RPT-02 Solar-Powered Headphones

Remember the days of all your headphones being wired? Then came the beautiful innovation of wireless headphones, and you could finally do away with the tangled up ball of cords in your pocket.

But along with that improvement came a downside, too: Wireless headphones need to be charged to stay functional. And if you forget to plug them in overnight, you might be without your favorite tunes on your morning commute.

That’s why Adidas’s RPT-02 Solar-Powered Headphones truly represent the next innovation in wireless. Through their passive solar charging capabilities, you basically never have to worry about running out of juice. And since they have an 80 hour playback capacity, you’ll always have an opportunity to charge them up once daylight breaks.
