I have only used them for 30 minutes or so, but once I got passed set up and tweaking the sound I'm enjoying them. They actually sound really good and I am happy with my purchase.
This is the third or fourth pair of Jlab earbuds I've had. Unfortunately they are easy to loose, thus the number of replacements. All around a good product. Mostly use to listen to podcasts while walking the dog. Never had any problems. Other than losing them!
