This charger is much faster than my usual wired chargers. These might be good for kids who dont complain as much as me but a solid three for what I used them for The overall drivers arent as strong as I would expect from these kind of headphones. This mouse right here is my endgame. While I can read text clearer on the Reverb at eye level, looking up or down with my eyes makes the visuals MUCH WORSE than the Index. The on/off button also pauses during playing sound. I didnt want to have to send them back, so bought memory foam insoles to put in them. My main gripe and complaint about these is that i followed the directions pairing them and they seem to be OK quality buds. These follow the fully in-ear style with their bulbous shape. If you expect anything more you might just need a custom made shoe rack or a wooden furniture piece.
