adidas' RPT-02 SOL is an innovative and sustainable pair of headphones that not only makes the most of a high percentage of recycled materials, but also the power of the sun. The solar-powered headphones are designed to support the brand's vision for a more sustainable future. Notably, the light-powered headphones will be able to be recharged with a variety of sources, including indoor lighting.
As compared to other headphones on the market that feature solar charging technology, adidas' RPT-02 SOL sets itself apart with a more compact and lighter design that's better suited to training.
While wireless headphones are currently limited to offering a limited number of hours of battery life before needing to be replenished, this design has the potential to open up new possibilities and "eternal playtime."
