I got these to use at work for 8 hour shift walking/running, and have used them for about two weeks. I tend to have small ears so I used the provided smaller rubber bud and it fits well. It blocks sound well enough and has a firm fit even when pulled out just slightly. I have to pull it out because I found the size of the stock of the bud tends to hurt my ears after several hours of use when pushed in all the way.
Marketed with a 6-hour battery but these are never less than 1/3 battery left after 8 hour shift. And once the low battery signal begins I tend to get at least another 30 mins out of the buds. This could also be because I keep them on lowest volume but even lowest is plenty loud enough even with loud machines around me, and the sound quality is still really good with those machines running. It does tend to be a tad base heavy, but i think most people like that.
I also run with them, and because the battery is on the back it tends to slide back a bit, but the cords have an adjustable clip to keep the wires together which prevents it sliding off. They also tend to dangle and swing when not in my ears, which i dislike, and the provided "cord management" method of unthreading them and drooping them down the back is a hassle for me, so I just leave them in the shaped rubber.
All in all I like them, just not when the buds are out. If you need to take out the buds, might as well take off the set.
Buds stay in place well, Long Battery, Wire clip, Good sound, Good connectivity, Low sound transmit through wires.
Can slip off when running, Cords dangle/swing when not in use.
