RUIMEN Bluetooth Audio Smart Glasses for Men Women, Smart Sunglasses with Speakers and Mics Open Ear Music Hands-Free Calling, Volume Control, Anti-UV Lens, IP4 Waterproof Classic Black Standard Size

Was a bit leery but for the price these are fantastic! I'm using Spotify through my phone... everything sounds clear including calls! I'm not sure why people are complaining about sound... I control the volume with the controls on my phone & it gets pretty freaking loud! It's very simple to use... if you read the instructions thoroughly there's no room for error!

These glasses are pretty cool. I can listen to music and take calls on them. I use them for riding my ebike. They still allow me to hear my surroundings. Although at 20 mph they aren’t very loud but then again, they aren’t made for that so I guess I can’t complain! They’re comfortable and I love that they’re polarized!

I feel a lil like James Bond with these shades on. I'm not much of a headphones guy. So, these sunglasses let me jam to my tunes without my ear plugged. That means I can hear the music and sounds around me while I'm out and about. The sunglasses allow you to seamlessly talk on the phone without having anything at your ear. I was surprised how well I could clearly hear the other person on a phone call, and they seemed to have no trouble hearing me. Not sure how they engineered such a crafty device, but they pulled it off with style.

Sound very low

Everything works perfectly

These smart glasses have a poor build quality with cheap plastic, horrible built in speakers, and a very poor volume quality. Very quiet and muffled especially for the price point, I received them and sent in a return request immediately

Pretty clear could be louder but its good for.the price really better than i expected.

The glasses are great.. the sound is robust, the calls are clear, and the price is RIGHT! The only reason I give it 4 stars instead of 5 is because the glasses are not high gloss black as described-they are a matte finish. Minus the finish, these glasses are great and my dad is happy on his birthday... that's what matters most. I definitely recommend.No, these are not as nice looking as the Bose or RayBan brands BUT they are a wonderful comparison in ability.
