They uncomfortable sounds, beyond an hour they become unbearable.
The next track button malfunction on my android.
The sound is bad, especially the bass that sounds extremely low, and must be hyper amplified with an equalizer, and even they do not really listen to pleasant sounds.
By running the cord vibrates and makes a noise unbearable, thus unusable for running.
Bike they take very well wind noise, thus unusable for cycling.
Running no particular worries.
