These glasses are awesome! The Bose sound can’t be beat! They look stylish and lenses are not too dark. They don’t seem heavy. My only small complaint and the reason for 4 stars is the ear pieces where the speakers are located are a bit too close to the top of my ear and can start hurting a little after a while. I wish they extended back more. Because of that, they tend to side forward sometimes. However, I really do love them. No one can hear the music where you’re wearing them, which is way cool!

These are great to walk/run and not have over ear headphones or ear buds. Very good for podcast/vocals, not so great for music but it's to be expected. Love them! Also got the polarized lenses and work great. Bought some silicone nose pads to help from sliding off, and they came with these little ear hooks. Now they won't slide off.

I was pretty excited to buy these so I can lay out in the pool. Figured I can kill two birds with one stone having the protection of sunglasses and music in my ear. Witch in itself is awesome. I am loving them. I DON'T regret buying them! However, there are a few downsides that can be improved upon. First, the battery life. When your relaxing all day in a pool, or out and about for the day, the last thing you want to do is stop the fun to charge your sunglasses. Lol, you kinda need them. Then you lose your music. Basically your Good time is interrupted early. Second, I noticed the signal is interrupted if you lower your head. For example: laying on your stomach on your float in a pool. I kept having to keep my head up, it hurt my neck and prevented me from really relaxing. Third, I didn't think about being around people when I saw these. When my Fiancee would join me in the pool, we were constantly having to pause the music or lift up the glasses to listen and talk, Lol. (YES, I bought him a pair for Father's Day, too) Last, they could be darker. Before I bought these I had a really dark pair of regular sunglasses that I used outside. These are no where near as dark. So in conclusion these are super cool if you're hanging solo for a little while sitting upright. Other than that, I find myself taking my old pair of dark sunglasses and portable speaker outside with me so after these die or if I want to lay on my stomach in the pool or lounge chair, I'll have an easier alternative.

I wish I knew they made them in prescription frames as well I would have waited. But they're so good I think it will be worth owning both pairs. The sound is excellent and background noise is not a distraction. Quick charging but talk time is @ 3hrs before it starts reducing and sound isn't as crisp. Interferes with other Bluetooth devices in that it dominates even when you don't want it to. I still don't understand the volume increase without disconnecting the call. That could have been made a little simpler but otherwise its better than any headphones and no worries about ear irritation from buds. Lastly do not use at night it distorts the road and all that you see and depth is hard to tell.

OMG these BOSE sunglasses are the Bomb. I got the Alto's. Look like Rayban's. I always have a earpiece in my ear for easy access/constant talking. Now I can just put on my shades and bam I have bluetooth. These are super cool. I'm so happy I was surfing on BESTBUY.COM and seen these. Another cool thing is you can change lenses. (sold separately) a must buy.
