More than solar-powered
Most good wireless headphones have good battery life (20-30 hours). They can last a day or two or even a week without charging depending on usage. But you tend to forget to charge them after use and eventually you end up with bluetooth headphones without power.
JBL‘s Reflect Eternal headphones does not need to be charged manually. It seems it never needs to charged unless all light in this world is extinguished.
The more time you spend outside with the Reflect Eternal, the more playtime you get. 1.5 hours of exposure to the sun per day can give you up to 68 hours of playtime. If you spend 2 hours outside per day with the headphones you can get 168 hours of playtime. You get basically unlimited playtime if you spend 2.5 hours per day outside with the sun shining.
However, it's not just the sun giving the JBL power. It also uses artificial light from indoor lighting to charge itself. It's not as good as charging it outdoors where the light is more intense but it helps.
In case you live in the dark, the JBL Reflect Eternal has a 24 hour battery life and takes 2 hours for a full charge from empty. You can also a 15 minute quick charge for 2 hours of playtime.
The JBL Reflect Eternal's incredible ability to charge itself with both indoor and outdoor light with such efficiency is all thanks to the Powerfoil technology by the Swedish company Exeger.
According to Exeger, Powerfoil is a photovoltaic technology that converts photons into energy through their special nano material, just like chlorophyll in plants.
Powerfoil looks nothing like typical solar panels. They can be integrated into logos, artwork, photos, patterns, and textures. They can bend and turn without breaking and printed in any shape.
Hence you don't see any sign of solar cells on the JBL Reflect Eternal. It's the first headphones to use Powerfoil technology.

JBL is seeking funding for the Reflect Eternal on Indiegogo and is now in the prototype stage. It has already been fully funded and it's a great opportunity to get the headphones at a heavily discounted price. It's a great deal for a headphones with unlimited playtime at that price. People would probably still buy it if it were more expensive.
