I use the headphones a lot for the gym, however due to the design of the headphones, when doing any exercise which tilts your head back, the headphones slip off your head, it’s quite annoying, as a work around I put the headphones the wrong way on I.e. right side on the left and vice versa, that makes the headphones more stable on the head. That is okay for me as a temp measure coz if I have to speak on the mic with the headphones the other way around, then the mic is not effective . Other than that the sound clarity the bass effect is the best I have ever come across.
