The latest wireless headphones from the Swedish company Urbanista hide an ingenious solution to battery life woes: solar charging.
The Los Angeles cost £169 ($199/A$349) and look no different from a normal set of headphones, apart from a flexible Powerfoyle solar cell on top of the headband.
Fairly compact with simple, clean lines, they are available in either black or gold, the first of which helps the solar strip blend in the most. They feel solid and well made with a soft-touch finish, but are slightly heavier than the market-leading Sony 1000XM4.
The Los Angeles are standard Bluetooth 5.0 headphones supporting the universal SBC and AAC audio formats used by most devices, and maintained a solid connection to various Apple and Android devices.
The right ear cup has three buttons for controlling playback and volume. Taking off the headphones also pauses the music. The left ear cup has a button for adjusting the noise-cancelling functions and a USB-C port for charging. They lack a 3.5mm headphone socket for using them without Bluetooth, which is irritating for use on a plane.
But where the headphones really stand out is through battery life. Without the solar charging the headphones last a tremendous 80 hours on battery (50 hours with ANC on), which is far longer than most competitors. But the solar charging makes them last almost indefinitely unless you only use them in a darkened room.
When the battery charge drops below 90%, the solar strip tops it up when exposed to sufficient sun or artificial light. In my time testing the battery never dropped below 50%, topping them up by leaving the headband facing a window when not in use.
Urbanista estimates that the battery will maintain in excess of 80% of its original capacity for more than 300 full charge cycles, but it is not replaceable nor are the headphones repairable, ultimately making them disposable.
The headphones do not contain any recycled materials. The company does not offer trade-in or recycling, nor does it publish environmental impact assessments.
The ambient sound mode is fairly good too, allowing you to listen out for announcements or traffic, but struggles with wind noise.
The headphones have a reasonably wide and expansive sound that handles tracks with plenty of energy. But the sound is skewed to the low end with plenty of well-controlled, punchy bass producing lower notes than most headphones can manage. Treble and high tones are pretty good, but will get squashed by the bass. There is no equaliser available to manually turn it down, sadly.
Feed them some high energy electronica and they sound great, but less so with classical music or more nuanced tracks. Activating the noise-cancelling makes them sound slightly less wide, expansive and energetic.
The Urbanista Los Angeles cost £169 ($199/A$349) and are available in black or gold.
The Urbanista Los Angeles are the first solar-charging headphones on the market and deliver on one thing above all else: almost limitless battery life.
Despite their solar credentials, the headphones are not repairable and the battery is not replaceable making them ultimately disposable and losing them a star.
