Again, late night, can't sleep, what to do....search Amazon! This is yet another purchase that my husband immediately sticks up his nose to, but not for long! These glasses are amazing. We walk daily and can listen to the music of our choice which makes walking much more fun. If your phone rings, the microphone tells you who's calling and a tap of a button on the side of the glasses and you're connected to your call. If you want to fast forward or pause your music, just tap the button on the side of the frame. The sound is 100% Bose quality. The lenses are a brilliant shade of whatever makes the sky a beautiful blue! The lenses are so clear and dark enough that you can't see your eyes. Lenses are scratch and break resistant. Oh! Forgot to mention that you can control the volume on the side of the frame where the Bose logo is by sliding your finger forward or backward. It's simply an amazing product. We just got back from a road trip where my husband had to make several conference calls. I was able to wear my sunglasses and listen to my audio book or music while he talked on his Bose sun glasses. Clear as a bell reception and no complaints from those he spoke with. I basically bought them so my husband could listen to music and talk on the phone in his convertible, and when we go boating, but we wear them all the time now. I can't imagine living without them. They are lightweight and fit really well. I'm super sensitive to bright lights, and these glasses fit perfectly and give my eyes the protection that they need. I'm so happy with this purchase and my husband LOVES them! Highly recommend them. 100% worth every penny. The sound is AMAZING! You can spend the same amount of money on sunglasses, and we have plenty of them, but nothing comes close to these!

Good fit, sound is amazing, solid build. Great for walking and running, but the catch when running "¦ all is good until @ 2 or 3 km, then they start to slip a bit. This slipping stage lasts for 1 to 2 km, and then all is good. Whatever the issue, hasn't prevented me from wearing them on longer days of > 10km

First things first, if you're considering these AND you're an audiophile, you'll be disappointed w/ these, but one should keep in mind, these are little speakers, on your temples, from sunglasses. They're not going to be airpods pro, or Bose QC over ear great, but they will do a decent enough job for what they are. Next, Dinged them for comfort a little, for those of us w/ big noggins, these are tight initially, but they do loosen with wear, so give it time if they're a little snug on your temples. I scored them on sale, 50% off, and am quite happy with them.

I love the sound and nothing in the ears. Don't charge with a 2amp charger, may overheat device and break it. Don't leave in hot places.

Simply put the glasses are okay, a bit big but then considering they have great sound it's understandable.
The thing that gets me is Bose's instructions. There are almost none.
They force you to download their app to get further details and instructions on how to use the features of these really expensive sunglass/stereo.
Then after they've got your info and your all signed up they leave you hanging and send you to a page to buy more stuff.
Bose, come on your app doesn't even have a detailed explanation of the product I just bought!
The written "how to" is a joke.
I guess I'm stuck going to YouTube to find a channel that goes through the features and the "how to's" of these really nice sunglasses and stereo combo.

Update: After going to YouTube and finding all the features (by the way not on the Bose channel) listening to these Tempo sunglasses I've upgraded my rating to 4 stars because it really is a great product. I just wished that Bose made it simpler for new customers to get the instructions on their new product.
