The popular RPT-01 in-ear training headphones from Adidas they’ve been redesigned to work with a power source that will be with you wherever your outdoor training sessions take you. The Adidas RPT-02 SUN from $229 they are equipped with a headband that can harvest solar energy, which is used to keep their internal rechargeable battery topped up with power. It goes on sale August 23 at adidasheadphones.com.
It’s not the first time a company has released a set of solar-powered headphones. Urbanista did it in 2021 with his Los Angeles headphones. But the Angels are a larger, over-the-ear model that isn’t particularly suited to workouts, which arguably makes the Adidas RPT-02 SOL a better fit for the benefits of solar charging.
Like the one in Los Angeles, the RPT-02 SOL uses a Powerfoyle light-harvesting solar cell from Stockholm-based Exeger. You probably won’t be able to charge them with solar power alone, but if you start with a full charge – which Adidas claims is good for a remarkable 80 hours – and spend most of your playing time outside, you might theoretically never need to plug them in again.
To help you understand how solar charging works, you can see real-time information in the companion app, and there’s an LED indicator on the headband that tells you when you’ve placed the headphones in bright enough light.
When we tested the Angels, we found that they lived up to their claims, but only if you could spend a good amount of time each day in very bright conditions – most interior lighting wasn’t enough to offset the power drain on the battery. of regular use.
As well as being environmentally friendly from an energy perspective, the company says the headphones have been made sustainably. 51% of the product is made of plastic and that material is composed of 87% post-consumer recycled plastics.
Like the RPT-01, the RPT-02 SOL is IPX4 waterproof, and all fabric components on the headband and ear cushions are washable, handy for repeated use with sweaty workouts. But apart from its larger battery capacity (80 hours vs. 40) and its solar charging capabilities, the RPT-02 SOL appears to be virtually identical to its non-solar sibling. Given the $60 price difference (the RPT-01 sells for $170), you’ll need to be very dedicated to helping the planet — and working out on bright days — to find the extra money a worthwhile expense. .
