A:AnswerYou can use your phone and the ear piece to control volume. The ear buds do have a little light on the bottom of the ear bud while in use. I try to go to bed with these on, in complete darkness, but my son sees the light on and will start asking about it. I gotta take them off or maybe just put a tiny piece of tape or something over the pinhole sized light.
A:AnswerThe sound quality is better than then the ones that I have owned. The quality is great and I can hear crystal clear when I am using them. They are volume controlled, just by touching the one ear piece.
A:AnswerI have a power strip that has USB ports on it, but you can buy a wall charger with a USB port just about anywhere, like best buy, walmart, target, etc. Or if you have a phone charger that plugs into the wall you could unplug the phone cord and use that wall part to charge your headphones.
