I like the sound, some people don't, but I like it. I also like the way they fit. I use complyfoam.com with them and this is perfect. What I like the most is the connection range. I left my iPhone on the floor and went to another side of my gym and music was still there. Almost lost the phone that day

I also like that long press volume up skip to the next song, long press on the volume minus goes to the previous song. I don't need to count 1-2, 1-2-3 like I do with my Bose QC35.
I tried JayBird Freedom and it was not mine. 1. Control is heavy with a charging clip. 2. I misplaced my charging clip and couldn't charge them.
I don't recommend to buy X2 now full price, only a a huge discount, new X3 are coming very soon(rumors).
