Pairing is simple and quick and I was listening to music within 2 minutes of opening the package. Ive had these about a week, and I noticed one was coming unraveled. Theres a small boost in soundstage and clarity. The general appearance, apart from the sole, is of considerable wear and really not that different from the ones that are 6 years old. put one pair at the front and one at the back doors on racks . the height of the toe box is not sufficient. I use both, but you can probably get away with one product. Charging-Apparently, when you charge it, youre really charging the case (or maybe the case and the buds), so if I listen for an hour, take them off and case them, theyre being recharged. This is heightened by the fact that she sometimes seems to have a slight(?) crush on you, stands quite inappropriately close to you, etc. it was a little big on me but it has an adjustment so i can make it tighter or looser on my waist.
