1.uses C type charger
2.the sound is loud and clear with no problems
3.the name on the box is gone as I used to put it in my bag and it got erased
4.touch works great
5.the only flaw is that the mesh of the right earbud slightly went in while I was trying to clean the inside but there's no problem to the sound it's the same (picture of this is at the last)
6. the sound of the right bud is lil less than the left one (but when both are used u won't feel anything)
7. mic works perfectly (quad mic)
