JBL claims that its new Reflect Eternal headphones can deliver "infinite" battery life

To some, wireless headphones are the un-tethered, tangle-negating audio devices of their dreams. However, as with most such products, they often become part of a regular charging routine in order to keep them going. JBL may have developed a solution to this cycle in its new Reflect Eternal product. The company asserts that they are self-charging, and, as such, would never run out of battery abruptly on the street again.

The Reflect Eternals apparently owe their ground-breaking new ability to Exeger's Powerfoyle technology, described as capable of converting light, whether artificial or natural, into battery power. It is found in the headband of these new wearables, and may thus avoid the need for conventional charging.

JBL claims that 1.5 hours of exposure to appreciable light results in 68 hours' worth of listening time with the Reflect Eternals. 2 hours of the same apparently engenders a total of 168 hours of on-time, whereas 2 and a half hours is associated with infinite headphone use. However, those estimates are based on certain use conditions and the caveat that the user has to be able to go outside for the "self-charging" durations specified.

Nevertheless, should the Powerfoyle-enhanced band somehow fail to be that reliable, JBL has also integrated USB charging (the type of which is not made clear; however, it confers 2 hours of listening time in exchange for 15 minutes of being plugged in) into the Reflect Eternals. They are currently available as an Indiegogo reward for a minimum of US$99 (correct at the time of writing); however, they ship to the US or Germany only.
