Adidas Headphones has developed self-charging headphones using solar cells from Swedish supplier Exeger.

Built from 51% recycled plastics, the adidas RPT-02 SOL headphones remove the need for cables and allow consumers to be less reliant on charging from the grid. The headphones use Exeger’s dye sensitized solar cell (SC) technology that converts all forms of light into energy and works indorrs and out.

The adidas RPT-02 SOL is part of Zound Industries portfolio brands and includes a light indicator on the headband which helps detect the strongest light source to generate the best charge. The headphones are also IPX4-rated (sweat-proof and splash-proof) and come equipped with a companion app where users can track charging and battery status in real-time.

The flexible solar cells are integrated directly into the headband of adidas RPT-02 SOL and reduce the need to charge from the wall.

“We’re so excited to partner with adidas Headphones and see our Powerfoyle technology come to life through consumer electronics that will be used by people in their everyday lives,” said Giovanni Fili, Founder and CEO of Exeger. “This partnership marks yet another step towards bringing Powerfoyle to the masses through sustainable audio products.” 

“Light is such a powerful and positive form of energy and it’s extremely exciting that we can now use it to power headphones,” adds Anders Olsson, Product Manager at Zound Industries. “Through our partnership with Exeger, we’ve been able to develop a product that’s truly best-in-class. The headphones are designed for athletes, and it’s been important for us to offer something that allows them to focus on performance without having to worry about the battery in their headphones running out.” 

The adidas RPT-02 SOL headphones retail for $229.00 USD / £195.95 GBP and are available on and
