to "homeOS" could be an indication that Apple is working on a new operating system aimed for use within a person's home. On the other hand, this reviewer found the Soprano to be a great fit, but others found it too tight.

Sure, you can turn on transparency mode on your AirPods, but it's still not the same as leaving your ears fully open. One thing we’re disappointed to find with the Frames Tenor and Soprano is the use of a proprietary charging port on the right arm.

Wearing any of the new Frames models is an interesting experience – despite their large appearance, they’re fairly light and don’t weigh down on your nose. Redesigned for luxury — Thoughtfully refined and strikingly elegant, the latest Bose sunglasses blend enhanced features and designs for an elevated way to listen. Double taps will bring up your preferred digital assistant (Siri or Google Assistant, depending on your paired phone's platform), while laying the Frames upside down anywhere will turn them off – another great feature that makes them user-friendly as it's a natural thing to do when removing any pair of sunglasses. Without a visual component, many people thought Bluetooth audio sunglasses were a somewhat silly idea.

It’s great to be able to have music chiming in your ears while wearing sunglasses and not having to balance headphones as well. However, we found that volume controls work really well in the Tenor and Soprano, but aren't as smooth on the Tempo, presumably because of the different materials used – the former two have premium, smooth plastic, while the latter uses a matte finish.

Mind you, it's not like listening to music on dedicated headphones or earphones, but it's still quite impressive.

You can easily pair them with your smartphone using the accompanying Bose Music app, but you won’t be able to adjust EQ levels in any way. Bose has shifted the button much further back as compared to the older models, which prevents accidental presses when you’re taking them off.This means keeping track of yet another charging cable instead of using a USB-C cable, which oddly you can find on the Frames Tempo. Personalise the style of your Bose Frames Soprano Bluetooth Audio Sunglasses with limited edition coloured lenses (sold separately).

One thing you’ll immediately notice about the Frames, however, is just how thick the arms are, but there's no way around that issue. Even in a relatively empty bus, the sound of the engine was enough to drown out the Soprano at full volume. It’s an experience that leaves you free to engage with the world, all while discreetly listening to music. In 2019, she signed up with AppleInsider, where she covers all things Apple, with a focus on tech rev.The Tempo fit can be adjusted by swapping out the nose clamps, but finding the right fit isn't easy. There's a major difference in sound quality and loudness between the Tempo and the two everyday sunnies. One issue I took with the first-generation frames was how it felt like they were digging into the tops of my ears. Again, given the Tempo has been designed for athletes, they benefit from 22mm drivers in each arm and the sound is surprisingly bassy.
