These smart sunglasses are a fun and functional accessory. The sound is great and these have background noise cancellation. They are lightweight and comfortable, as well. The lenses are fantastic and do a great job of protecting my eyes. The frames are well-made and very sturdy. They fit my face perfectly, which is usually an issue for me. I never like the way sunglasses look on me, but I really like these. The included instructions are easy to follow and include pictures as well. I do want to point out that it does say in the instructions that it contains magnetic material which may interfere with medical devices. Overall, these are a nice pair of sunglasses that are also functional for every day life.

This isn't my first pair of SOLOS smart glasses. I wear a pair of them at work all day with the blue light blocking lenses and quietly listen to music without bothering anyone. Not only is my eye strain gone, but I don't have to ask anyone to repeat themselves when they come to me with questions. My plan was originally to just purchase the front frame with sunglasses lenses in them and just change out the sides as needed after work, but came to realize it would just be another hassle to add to the day.

So, I just got another pair and the leave the other ones at work to charge as needed and use these after work driving home and for my evening walks. They are comfortable where they need to be, easy to use and the charge lasts quite a long time. I'm my case the sunglasses last about 6 days then they need a charge. Keep in mind I walk for an hour a day and sometimes an hour and half. The ones at work last a full day of work (8 hours) and then need to be charged. They are comfortable and can easily be worn even if the battery has been depleted for the day.

Keep in mind these are similar to bone conduction in which nothing really enters the ear and instead speakers are placed really close to the ear also allowing ambient sounds in as needed. In my case for safety I need to be aware of my surrounding and be able to hear everything.

I bought these glasses because Apple's AirPods were falling out of my ears and I would constantly lose one of them when hiking or running, a total waste of money IMHO. Another issue with Apple buds is that to control sound volume I need to use my phone or watch, which is a distraction. Solos, on the contrary, works like a charm. It is super easy to adjust the volume level when listening to music, answering a call and talking while walking and hiking. I don't need to pull out my phone, everything is controlled with gestures on the right ear arm. Great!

First impressions. The glasses come disassembled in 3 pieces - the frame and two ear arms. All the electronics are hosted in the earpieces and the frame is interchangeable, which is awesome because it allows you to have several different styles by swapping the frame without the need to buy the most expensive part of the glasses - earpieces. Heck, you can even have prescription glasses frame on it! Putting glasses together was quick and easy - just "click-in" the earpieces into the frame and you are good to go, 5 sec. Then you need to turn on the glasses (the button is at the bottom side of the right ear arm) and connect them to your phone via Bluetooth just like a set of wireless headphones. Just install "Solos AirGo'' app on your phone and it will walk you through all necessary steps to get it up and running. A few minutes later you are ready to use your new awesome smart glasses!

Operations. The sound is crisp and clear, it's loud but not overwhelming. It uses a half-open double speaker design instead of bone conductivity technology for sound transfer. This design does not lead to high vibration at a low frequency or a poor high-frequency response, and, therefore, does not cause low sound quality or distortions. I really like that the glasses automatically detect when you put them on or off and adjust sound volume accordingly so you can hear voice prompts even when you have your glasses off. When you take them off and don't use them for several minutes (can be set up in the app) they'll go to sleep to preserve battery life automatically. Great but I'm missing a feature that would disconnect the glasses from my phone as soon as take them off and connect back when I put them on for a smooth sound transition, hope the manufacturer will add it in future updates as the glasses already have a proximity sensor in their ear arms and know when they are on or off your head.

Now about the microphone. As expected, it also works great, much better than my Apple AirPods' one. It uses so-called "Whisper" noise cancellation tech developed by Solo. From what I've read and understood, it's aimed to cancel all types of surrounding noise and at the same time boost only the narrow bandwidth of speech signal from the person wearing the glasses. Solos claims that the surrounding noise can be reduced by a whopping 45 dB, and I tend to believe this claim after testing calls with it.

Other thoughts. The glasses' battery life is a whopping 11 hours of continuous listening to music and 8 hours making phone calls. And on standby they will last for 3 days. The device comes with a beautiful case and cleaning fabric. A special charging cable is included, you can't use any random USB cable. The glasses are very well made as expected for such an expensive technology/fashion piece, the style is classic and very cool. They fit well and are very comfortable, weighing only 30 grams! End-to-end, I really like them, and I love that you can always swap the frame if you break it so I don't need to be worried too much. The only thing that I'm a bit concerned about is privacy because their speakers are semi-open and located in the ear arms outside of your ear, which means that everything that you play loudly can be overheard by a bystander. Just be aware of this side effect. But I consider it a minor issue as I primarily use them for music, and I don't make any super-secret calls :).

A few words about the Solos AirGo app. It allows you to control almost everything about these glasses, calibrate them and update firmware. It also includes a number of "AI coach" and "AI are" features aimed at improving your daily quality of life by providing you with AI-powered fitness and daily routine guidance. I personally did not use any of these features as I need them for audio playback and calls mostly and we already have way too much AI assistance in our devices, but there are some very interesting ones like, posture monitoring, posture exercises, reminders to drink water, etc., that I might just give a try soon. I'll be updating my review as I'll continue to use the glasses and gain more experience with them.

*** Bottom line ***
Yes, I totally recommend them, these are my first smart glasses and I'm very impressed by their sound quality and overall usability. They are easy to set up and use, very comfortable to wear and very intuitive to operate. They are packed with tons of features and pr...
