Great battery life, fast charge. But power button broke after 5 months of use.

These are nice earbuds. They fit well, and stay in. Nice battery life. Good features, like be aware sound control. Sound is pretty good. Not the best I have had in these types of buds, but for what I use them for they are fine and a fair price for all you get. had them for about a month.

Excellent headphones. Good volume. Battery life actually more like 8 hrs of solid music play tops. After 9 months of regular use the battery no longer holds charge

I bought 3 pairs of these, 1 for myself and 2 more for family. We all seem to have similar experiences - after about a month of use. And we tested them on a 30 hour, non-stop road trip. 1.) Battery life. It's nothing like the 25 hours the manufacturer claims. It's closer to 12 -16 and if you have noise cancelation on "Hi" expect about 8. 2.) Noise cancelation. Minimally functional, at best. Even in the highest mode, It's nothing even remotely in the broad area of the Bose offerings. Seriously, it's silly that they even push it. 3.) Now, all that nasty review stuff said, the sound quality is outstanding. About as good a bass response as one could expect from buds, especially at this price. 4.) Comfort. Excellent. No sore ears or annoying rubs even after continued wear over hours upon hours. Also, it's worth noting, they fold up and carry in a pocket extremely well as to not be a nuicense. 5.) Longer term after 2 months, the R side died. It grew weekend and finally quit. I contacted the manufacturer and they were simply stellar. Immediately replaced them, no quibbling nor excuses. However, the replacement pair performed exactly like the originals and sumairially died. Both pairs the kids have died too. These buds last 60 days. I went back to the phenomenal bose products. Expensive but after 5 years and worn shiny in places, still function perfectly.

La cancelación de ruido nones óptima pero funciona para entornos bulliciosos. La calidad del sonido es buena pero no se puede personalizar
