Adidas RPT-02 SOL helmet review: the latest solar-powered technology


Why do wireless headphones always feel like they run out of battery at the most crucial moment? More than that, waiting for them to finally load can take forever and throw your systematic, flawless morning routine out the window.

Enter the Adidas RPT-02 SOL, a pair of self-charging, light-powered headphones. Using Powerfoyle technology transforms natural and artificial light into energy that will keep the battery level at 100% – no pesky wires needed.

Pretty impressive, right? We decided to put this bold claim to the test and see if they were as revolutionary as they sound by spending every waking moment blasting our playlist (dominated in the late 90s, early 2000s) .

Read on for our verdict.



  • Break: 80 hours (without any light)
  • Response frequency: 20Hz – 20kHz
  • Loading time: 2 hours
  • Loading port: USB-C
  • Microphone: Yes
  • Voice command: Yes

At first glance, you can tell straight away that these headphones are well-designed and as soon as you put them on your head, comfort sets in. There is plenty of padding around the ear and the headband can be adjusted slightly. Despite such a tough build, they’re incredibly lightweight and after wearing them for a few minutes, you can easily forget they’re even there.


Reading more into the design, the durability credentials are impressive. As with many new Adidas clothing lines, the negative impact on the environment has been significantly reduced. Made from 87% recycled plastics and without cables, these headphones are among the most durable on the market.


The standout feature is of course the Powerfoyle technology which powers the helmet with light alone. As all forms of light, including artificial light, can recharge battery levels, you don’t need to depend on the capricious British climate to provide a power source.

I’ve tried the headphones in a variety of places with varying levels of light, including having lunch in a brightly lit living room, jogging in the park on a cloudy morning, and taking a walk in the evening at sunset. Throughout all these tests, the battery life remained impressive at 100%.


But for the real test, I needed to know how quickly the battery life would drain, so I tested in complete darkness. I drew all the curtains, boiled the kettle, and set up for an in-in Saturday night with a cup of tea and an audiobook (Becoming by Michelle Obama — if you must know). A few hours later, the battery level had barely changed and when exposed to light again, they recharged in just 30 minutes. Offering 80 hours of memory life, you’ll never have to worry about battery life again.

For the next grueling review, I tried them out over an intense hour-long workout and they proved to be a great gym companion – the IPX4 rated design makes them fully sweat and splash proof . The inner headband and ear pads are also removable and washable so you can quickly wipe them down or wash them so they’re fresh for your next use. They’re not fully noise-cancelling, but volume levels can be adjusted to block out a lot of background noise.

To get the most out of this product, it is worth downloading the Adidas Headphones app. With the easy-to-use interface, you can easily control and customize features like sound levels.


Adidas has indeed shaken up the headphone market – the innovative technology is very impressive and other companies will no doubt follow with more solar powered technology.

Over a weekend of use, the battery barely drained and it automatically recharged with the slightest exposure to natural or artificial light. With energy bills rising, we’re grateful to have one less thing to constantly charge.
