The sound is great but I can't get them to stay in my ear all the way. And for some reason the volume just turns all the way down. Listening to music and just out if the blue the volume starts going down.Very comfortable, sounds great. Can’t speak to battery life yet. I honestly don’t use them often enough to wear down the battery since I bought them.Better sound quality than I expected. Worth with the price.Very comfortable and good fit. I wear them with my glasses even during biking or walking without any problem.Battery lasts at least few days.Love waterproof and easy pairing but struggling with phone call because I can only hear from right ear bud.. No issue to listen to music on my iPhone though.Really good sound for the price. Connects seamlessly with my iphone and LG TV. Mainly use for TV watching at night. Great battery life so just charge once and forget. Ear hooks are great for support. Love the overall experience.For something so little it has big sound.Easy to use. Great quality.I am not used to this shape ear bud so they go in funky, but once I have them positioned I don't even notice they are there! The cancel out noise really well! There is a charge indicator on the front of the box which is helpful. Overall, would totally buy again!The button is very sensitive. If you accidentally touch. It is pressedComfortable, no-slip, good sound (though I only use it listening to podcasts, not music; I have better headphones for music).I use them while biking, wearing only one at a time (so I can hear traffic) and they're great for this. I don't know about noise cancellation; there's still a lot of wind noise and I try to use wind blockers on my helmet to cut down so I don't have to have the volume so high. The only downside is the arm for my bike glasses has to sit on top of the arm for the earbuds, and since I only wear one at a time it makes things a little crooked, and apparently I have weird shaped ear canals because one side snugs easily but the other, in spite of trying the different sizes, doesn't really snug well.Would recommend these, and if I lost them I'd buy another.It’s a light weight earbuds that comes with a small package. I usually use it while I’m doing exercise in gym,it’s very comfortable for my ears,the sound is perfect. It’s automatic charged inside the box,very convenient.good quality product,also the price is great.Had some issues with syncing to phone but seller was very helpful. For the most part these are pretty decent headphones at a reasonable price.Hard to pair between sides and keep paired. Use for track power walking.
