Batteries suck, which has turn out to be much more of a problem over the previous few many years because the battery-dependent cell gadgets we’ve turn out to be hooked on now demand extra energy than ever. But so long as you’ve bought a supply of sunshine—be it the solar or soul-crushing office fluorescents—Urbanista’s new wireless earbuds will preserve charging all day lengthy.

It’s an concept the corporate launched final yr with its Urbanista Los Angeles wi-fi headphones. Integrated into the headscarf was Exeger’s Powerfoyle photo voltaic cell materials, which was be screen-printed onto versatile supplies, permitting the Los Angeles headphones’ headband to nonetheless flex and bend with out damaging the photo voltaic cells. The different benefit to Exeger’s tech is that it could actually harness vitality from each direct daylight in addition to much less intense indoor gentle sources, which allowed the headphones to recoup a cost even when used at evening subsequent to a lamp.

Although most reviewers discovered the photo voltaic cells labored finest in vibrant daylight, charging the headphones’ battery quicker than it was being drained even whereas listening to music, it was a intelligent concept, and one which Urbanista is now bringing to its wi-fi earbuds. But for the $149 Phoenix buds, which shall be accessible later this yr, Exeger’s Powerfoyle photo voltaic cells aren’t included on the buds themselves, however on the charging case. Given earbud charging instances are normally saved in pockets or deep in baggage, that makes recharging these headphones somewhat more durable than the Los Angeles, which expose the photo voltaic cells on a regular basis whereas in use. But Urbanista guarantees that for each hour the case is overlooked within the solar, sufficient cost needs to be collected for a further hour of powering the buds.

Battery life is rated at eight hours with the buds alone, plus a further 24 hours with the charging case, assuming you’re trapped on the darkish facet of the moon with out entry to any gentle. The case can be charged with a USB-C cable, and the buds function ANC, multi-device connectivity, and IPX4 water resistance for shrugging off sweat and occasional splashes. As for colorways, you’re restricted to a alternative of both black or pink, and we’d most likely suggest the latter if these are going to be sitting out within the solar for hours at a time.
