Input:
I have tried 10-15 pairs of in ear headphones, and these are the only ones that don't fall out when I run. The only issue is that the cord is so thin I end up having to replace them a few times a year. It's well worth it for me because these are the only headphones I can run with, very comfortable and the sound is great.
