There's a major difference in sound quality and loudness between the Tempo and the two everyday sunnies. Again, given the Tempo has been designed for athletes, they benefit from 22mm drivers in each arm and the sound is surprisingly bassy. Mind you, it's not like listening to music on dedicated headphones or earphones, but it's still quite impressive. On the other hand, the Tenor and Soprano have 16mm drivers, and the sound is still quite enjoyable. These two models aren't quite as loud as the Tempo – at 50% volume, the Tempo was more than sufficient on a riverside walk with squawking birds and chatting strollers, while we needed to up the volume on the Soprano to about 65% to enjoy our tunes.

The original Frames were pretty good about not leaking that much sound. Unless someone was standing pretty close to you, as long as you weren't cranking the volume all the way up, people couldn't even tell you were listening to something. With these new models, you'll get more sound leakage, particularly from the Tempo, and in quieter environments people will hear whatever audio you're playing if you have the volume high. But the majority of people will use these outdoors and sound disperses better outside, so you're probably not going to bother anyone.They’re both IPX2 water-resistance rated which, for a product meant for outdoor use, is lower than we’d like. They’ll be able to take a few drops of rain, but you’ll likely need to keep them out of a downpour. Then again, wearing sunglasses in the rain is a whole new world of looking like a fool. There’s also no great way of monitoring the battery life on the glasses. When you turn them on and off, you’ll be greeted with the battery amount in audio form, but it doesn’t offer a way to monitor how much charge is left over visually from the glasses themselves.

Polarised lenses have an odd tendency to distort the pavement, making it look less flat than it really is The Frames know which way you’re facing and your location from the GPS on your phone, so you can use audio to feed information about the real world into your ears. The Bose Rondo’s arms are 154mm long while the front of the glasses comes in at 142mm. The Alto are quite a bit bigger at 162mm arm length and 148mm across the front.The glasses sound amazingly good for what they are. Two small speakers sit in the frame just in front of your ears. The music is directed straight to your ear through small speaker grilles, while cancelling sound is projected out into the world. The result is a sound leakage of about 1%, according to Bose. That would have been a handy addition, but instead the glasses are charged via a proprietary cable that connects to a part inside the right arm of the product. Audio quality While neat however, even this doesn’t really show the true joy of using the device. A very robotic voice telling you it’s “220 meters to the green” is handy, but not especially fun. Sensors are hidden in the frames that can detect your head position and interactions such as taps to the side of the glasses. Photograph: Samuel Gibbs/The Guardian

You may want to add your prescription to your Bose audio sunglasses, or you may want to turn them into your everyday prescription glasses. Whatever you choose, Lensology can help. Offering the highest quality lenses in all the tints and gradients you can imagine, along with the most advanced prescription lenses, we are passionate about offering choice, quality and flexibility to our customers.Once you ditch the idea that ‘augmented reality’ must equate to ‘augmented vision’ you start to understand the Frames’ potential – and it really is the AR features that make the Frames an impressive piece of hardware. It’s worth noting how much bigger the Alto glasses are than the Rondo. Some people we handed them to with smaller heads found they wouldn’t sit on their face, so the size difference is something to consider here if you buy some. In the real world if you have the volume below 50% people sitting right next to you won’t hear it. In fact I took delight in the look of surprise on people’s faces when I gave them the Frames and they suddenly heard my tunes blasting out as they put them on. It’s really very impressive.
