Court-ordered ankle monitors bring in hundreds of millions of dollars in the U.S. every year. Law enforcement uses the devices to monitor more than a hundred thousand people every day, a number that’s expanding rapidly. They play a key role in American criminal justice. For such a crucial technology, though, they…
Tesla CEO Elon Musk quietly sold $6.9 billion worth of Tesla stock, according to a new SEC filing, despite saying as recently as April that he had no plans to sell any more. The stock sale comes as the billionaire continues to fight with Twitter in court over his attempt to back out of purchasing the social media…
SpaceX has cleared an important hurdle that brings it closer to the Starship system’s first orbital flight test. The company has successfully completed a static fire test of the Super Heavy’s current prototype, the Booster 7, a month after its previous attempt ended up in in flames. SpaceX used the Booster 7 for this test again but fired only a single Raptor engine on the orbital launch pad, igniting it for a few seconds to give engineers a close look at how it’s performing.
The Booster 7 is equipped with 33 Raptor version 2 engines meant to give it lift it needs to launch both the first stage itself and its upper stage companion, the Starship spacecraft. During the company’s previous static fire test attempt, the booster caught fire on the launch pad. Company chief Elon Musk revealed on Twitter back then that the issue had stemmed from the engine spin start test SpaceX had conducted and that going forward, the company “won’t do a spin start test with all 33 engines at once” anymore.

In addition to testing Booster 7, SpaceX also did a static fire test on two of the six Raptor engines on Starship 24. That’s the current prototype for the launch system’s upper stage, and it’s what will fly to space for the system’s first orbital flight test. It’s still unclear when SpaceX intends to send the Starship to orbit for the first time, but it likely has to conduct more testing before that happens, including static firing more of its Raptor engines.
Urbanista has revealed its latest set of earbuds, and you may never need to toss a charging brick in your bag if you travel with them. That’s because the Phoenix buds have a charging case with Exeger’s Powerfoyle solar cell material. The company says this can top up the case’s battery using any kind of indoor or outdoor light.
The earphones offer eight hours of playback time, according to Urbanista. The brand says the charging case has a total battery reserve of 32 hours as well. The Phoenix charging case looks much taller than cases for other true wireless earbuds, likely to ensure there’s sufficient surface area for the solar cell material.
The earbuds have hybrid active noise cancellation (ANC) support, along with noise-reducing microphones and a transparency mode. They have multipoint connectivity, meaning you can connect them to two devices at the same time. You’ll have access to touch and voice controls, as well as deeper customization through the Urbanista mobile app. There’s IPX4 water resistance too.

Urbanista previously used Powerfoyle tech in its Los Angeles over-ear headphones. In trying them out, we found that direct sunlight was able to charge them at a faster rate than the battery drained as a result of playback. However, the headphones charged much slower in ambient light.
It’s unclear who might be able to use the Phoenix buds to their full effect. If you’re outside a lot and are able to leave the case in direct sunlight while you’re using the earphones, you might never need to plug in the USB-C cable to top up the battery. At the very least, it’s an intriguing product that offers a look at another possible use case for the solar cell material.
The Phoenix earbuds are available in black or pink. A set costs $149/£129/€149.
