The glasses were a great fit and easy to link to my devices. The only reason i didn't give it 5 stars is you have to have the volume low so no one next to you can hear what ever you have playing. They make a great conversation pieceGot these glasses a few weeks ago and have been really happy with them. I've wanted a pair of smart sunglasses for a while but all the ones i've seen in the store are either massive/heavy, or they don't look like a pair of glasses i'd ever wear. They're super lightweight, and style-wise, they look like something you'd see in Sunglass Hut, not Best Buy. Bluetooth pairing was super easy and phone calls sounded really clear, so they've been perfect for when i'm driving. My only complaint is that the case that comes with the glasses is just a tiny bit small, so you kind of have to angle the glasses to allow the case to close properly. Overall, i'd definitely recommend.I have the Bose Rondo and Soprano, so I can’t help but compare the Lucyd to those. The Lucyd glasses have really bad audio leakage, whereas the Bose do not. My daughter and I can walk around the neighborhood listening to the Bose and hear only each other and not the other person’s music, but after only having the Lucyds a few hours, I am not sure that will be possible with these.I bought these because they were white and both the Bose that I have are black. I also do not like the polarized lenses. The Bose Soprano have these as well and it makes it hard to see your phone screen. Its bad on my eyes. I did buy the extra lenses for the Lucyds, so I plan to try them out.I have a small face (woman) and these don’t push back on my face well. The Bose Soprano is the same, but the Rondo, which are shaped like the Lucyds I bought fit the best for a small face. I feel the Lucyds slip a lot and if I bend over, I would be afraid they might fall off.The first time I connected the Lucyds to my iPhone, it said “connected “, but when I went to the Amazon Music app, music played out of my phone instead. I had to go back to phone settings and click to connect a second time before they were good to go. I will take these on vacation next month and see how they do.I picked up the LYTE Darkside glasses about a month ago.after trying out some cheaper Bluetooth glasses at work.I wanted a every day pair that actually looked good.After an eye appointment I had my new prescription put in them.I work on a freight dock currently and we can't have earbuds. these have been great. I don't even have to go max volume to hear a podcast with all the fork trucks driving around and I can still hear people around me too.I recently did a zoom interview with them along with some phone calls and the sound was great.listening to music you're not going to get low ends like with earbuds or headphones but it's a great alternative.with my new job I'm going to I'll have to be hands free so these will be perfect for phone calls when needed.I've even used them hiking. in the past I would have never done this because I need to hear everything going on around me. with these glasses I still can.Battery life has been great.I can listen to podcasts and music at high volume for 6 hours and only be at 60%lower volume lasts even longer.I have a decently large head (7 3/4 fitted hat) and these have been very comfortable to wear all day.Lucyd has a good tutorial video on YouTube that covers everything from function to adjusting the fit.as long as they hold up and the battery life lasts over time I'll definitely purchase another pair when I need a new prescription again.my only thing I'd recommend to Lucyd is to make clip-on sunglasses for people who get prescriptions put into them.I don't like transition lenses (which they do offer.) and finding a good pair is very hard that fit these glasses and look good.
