A simple solution to the constant problem of having to charge wireless earbuds is to make it so they never need a charge, at all. That means do not use an AC adapter or USB charger, and instead, use solar power. The JBL REFLECT Eternal headphones are solar-powered and never need charging.
The iconic audio company has been moving inexorably into the 21st century with Bluetooth enabled wireless speakers, headphones and other up-to-date tech-enabled audio equipment.
The headphones can turn artificial and natural light into energy through the Exeger Powerfoyle process. The company states “more light, more playtime” which is true in its basic aspects.
The self-charging portion of the process of charging for the JBL REFLECT Eternal can be slow, and sometimes not power up the headphones fast enough to keep playing music continuously.
The problem is resolved with a traditional USB cable to plug in the headphones and realize a 2-hour battery life in just 15 minutes of charging. JBL calls this speed charging.
The REFLECT Eternal builds up an ever-increasing charge the more time spent outside in natural sunlight each day. 1.5 hours outside equals 68 hours of playtime – anything over 2.5 hours outside each day, there is an endless charge to the battery and playtime never ends.
The solar power is stored in a 700mAh battery, which can last for 24 hours of playtime with a full charge – when the headphones have been in bright natural sunlight for more than 2.5 hours the result is a full charge. Hence the cycle of continuous playtime can be maintained.
There is a builtin microphone for calls and speech assistance software and a touch-sensitive side for activation of either Alexa or Google Assistant, which is a nice touch. The JBL REFLECT External comes in red and green.
JBL REFLECT Eternal supports BT 5.0 and have an IPX4 water resistance rating.
