To get the full potential out of these earphones you have to follow the instructions, you won't have good quality sound if you don't twist them in your ears like the app or the box says, if you do so you won't need to use noise cancellation and the battery will last 8 hours like it's advertised, I work in a really loud warehouse and I haven't felt the need to use noise cancellation because by giving the earphones a little twist you are making them fit well and they won't get out of your ears, also you need luck to get good ones that are clean and have everything with them , mine didn't came with the medium ear tips but I'm ok with the small ones and they came like New , so yeah they aren't for everyone, if you are not a person that follows instructions and can't remember the controls these aren't for you, but in my opinion they are great, good sound quality and good features. Take your chances maybe you will get lucky. The black ones have a higher price for a reason and that's probably because they are in better, I'm not affirming anything, just try your luck.

Sound is clear and loud enough. Fit is comfortable. Battery is reasonable. Like the size and the make.

Great headphones for a great price. Great sound. Great battery life. So comfortable that I can fall asleep in them. Honestly, this is my second pair. I lost the first… *** Sad Face **** Will buy again. P.S. don’t wear them in the shower….pahaha

The headphones are very good, they are light and easy to use, the battery is good and the charging cable is compatible with many computers, easy connection with iPhone and computers with Bluetooth, it feels like the materials of the headphones are of good quality and the sound is good for its price, I recommend it for people who only want to listen to music

I really really love my earbuds so far, they fit Ver comfortably, and and they sound amazing as Usual, plus I got a lot of hours to thoroughly enjoy them.
