I've been using these for running and they are working great so far. I needed some sunglasses for runs, and figured adding headphones that are not in-ear would be much safer than the ones I use in the gym. So far, these are perfect. I've had no connection issues, sound is plenty loud enough while letting in plenty of noise (I can hear bikers coming up on me, cars, etc.). Just what I needed.

I would say the sound quality on these is probably right around the $7 buds you buy at the store. The sunglasses are similar to the ones that you can get for probably $15-$20. So know what you are getting. The sound quality doesn't compare to my $40 in ears, but they aren't supposed to either.

The negatives I have had so far really are a me issue. I have a large head, and these are tight. I fear they may be rough on longer runs. I wish they could be adjusted so that they weren't so tight, but I will probably try to widen them (I'll let you know how it goes). Along with that, they fog up on me. I'm simply going to grab some spray for that as these work too well for me not to try to make work great. If you don't have a super large head, you are probably going to be just fine. Overall, great buy for the price.

I really like the product, especially the good sound quality for such a good price. The only problem for me is that the headphones on the sides are too long and go past my ear even on the shortest length setting; and then the sunglasses are off my face when I put the ear pieces in. Although there is this small problem, I still use these glasses every time I go for a bike ride and/or on a run. They are great and the glasses ensure that the headphones will not fall out. Wonderful idea!

Purchased this as a gift form my husband and he absolutely loves it! He likes that the headphones are not earbuds; they sit just over the opening of the ear comfortably for him. He's not an audiophile, so the sound quality is perfect for him since he is usually listening to audiobooks during his commute from work on public transit. It's not nosie cancelling, isolating, or reducing, so it still allows him to be able to hear what's going on around him for safety reasons. The best part was that it didn't cost a crazy amount of money, he loves how they look, and that if anything happens to them, we wouldn't break the bank to replace them.

These are the best value bluetooth headphone/sunglass combination on the market today.

1. Battery Life: 7-9 hours
2. Sound Quality : 7 out of 10
3. Connectivity: 10 out of 10
4. Water Resistance: 8 out of 10
5. Controls: 7 out of 10
6. Lifespan: 9 out of 10
7. Safety factor: 10 out of 10
8. Flexibility in use: 10 out of 10

Sound Quality is good based on the driver size and excellent based on the price and intended use.

Connectivity takes less than 10 seconds. Turn it on the first time, select it in your phones bluetooth settings and you are done. Use it till it dies.

I sweat a ton when I run and these get soaked. I also run in the rain and these work without issue. If I were to rate it by the IP Code, I would rate it an IP 5 to IP6. It probably would not survive immersion.

Controls are on the right side.
Short press center button - play/pause answer/hangup
Long press center button - power on/off or reset/pair
Long press top or bottom buttons, volume up/down
Short press top or bottom buttons, skip forward/back

I get about 2 years out of these glasses but I use them heavily, especially when running. At $10 per year, that is an exceptional value.

Safety factor? What? You have to be careful when running or riding on the road. You can pull the ear buds out and away from your ears, still hear your audio and easily hear traffic around you. The buttons are far enough apart that you can skip, pause, answer, hangup and adjust your volume without taking your eyes off the road.

Flexibility? The lenses are on a pivot and allow you to flip them up. This is good when you are sweating and need to cool your eyes or when the sun goes down. I run at night and use the clear lenses at night.

The ear buds are on an extendable tube which gives about a centimeter of adjustability. The charging port is under one of these tubes.

For less than $20,these rock. If you have a small face, the ear buds may be a bit to far back for a snug fit.

I have read most reviews about how bad these sunglasses are befor purchase, well it's not that bad do understandable why people complain well my dose the same thing like the some reviews BUT people understand this, WARNING speaker earpiece doesn't need to be all the way inside your ear due to your safety your surrounding you can also hear what's out there as well!!! Bike ride, walking, work break time, fishing thing like that.
