"Great for the gym - don't sweat on the volume rocker"3.5 starson by tahuichi
Pros: These sound great and the adjustable earpiece is perfect so that when on the treadmill the buds don't fall out of place.
Cons: I'm on my 2nd pair, need to return for a 3rd. The volume rocker and the pause/ advance song buttons stopped working again! Probably due to sweating on them, but that should be been considered in design.
Summary: When all the features are working, these are great. If the volume/ pause buttons always worked, these are ideal for running. One can quickly adjust the volume and advance the song with the music player safely tucked away. Just don't sweat on the buttons.
