They were amazing headphones for both the gym and on my runs

I have tried so many cheaper WIRED headphones during my workouts, and the wireless CX Sport is lightyears better than all of them

You're not going to confuse the audio quality with that of a good pair of over-ear headphones, but that being said, if you're looking for some headphones to wear while working out, you're probably not looking for some top of the line audiophile setup

These headphones are amazing
