Ive used these all regularly for a month now, that hasnt happened as of yet so very happy to this point. That said, the height is a bit too much, so the shoes are too loose on her feet to wear right now despite it being the right length (if a bit too long). I love the amount of spices that its able to hold. All the rhinestones were in place. I also like that I dont have to replace the battery anymore and no battery cover to lose. As a woman, one of the irritating things we constantly have to deal with is people trying to talk to us while we jog, walk, or hike. When I plug my EarPods in, they sound way better than these at higher volumes. The belts are very rigid and I do not think they will warp to conform to my corpulence like less rigid belts have done. They?re so comfy and feel so lovely. She is very happy and now listens to music all the time.
