Restored JBL Endurance JUMP Waterproof Wireless Sport In-Ear Headphones (Refurbished)

They sound great when firmly snuggled into the ear but with time and sweat, they will lose grip but won't fall off just reduce the bass. I like the on-off hook feature. I think it's very clever. The main issue I have is that people can barely hear me when talking on the phone. I just don't bother answering phone calls. It will also be nice if the cable would have been 2-3cm (1 inch) longer.

I do like these earphones. When I put in one ear they sound great. But for me there is a fundamental problem.... the cable between each ear is too short. As soon as I put in the second ear, the first earpiece is pulled loose by the now taught cable running around the back of my neck. So the sound is much worse and eventually, they fall out. I don't understand why no one else gets this problem. I am not a big guy and my neck isn't big. My wife has no problem as she has a lovely, slim, feminine neck.
