The sound is good, the charge is kept for a long time, do not fall out of the ear if you learn how to put it correctly, it is pleasant to the touch, I bought them a year ago, the armor work perfectly, so I decided to take exactly the same dark price for a pleasant one. There is a phrase on the box on the box, if you go there it will be possible to adjust the sound under yourself, but from the basic settings it is not that the sound would be strong and changed, but nevertheless you can correct the sensitive, well, and so I basically look at the widget in the phone how much charge is left and that's it.
