The controls always work, the headphones stay in place no matter how sweaty you or or how much your moving. I've had these headphones for years. My second pair. First set last for 6 years until one of the headphones stopped working (Tried troubleshooting). I'm also pleased the price has gone down since last time I purchased them. I'm hoping the quality and durability is the same!
This is now my second set of J-Lab buds and each time within a matter of months the case finds a fault and wont charge one of the buds rendering them useless. Its a shame as sound quality, app and comfort are great. These have been used for intended purpose; gym, general use and taking calls. Stored safely in a bag and cleaned regularly. I know faults can happen but twice with one brand means J-Lab need to review theie hardware reliability.
