The connection stayed stable & the fitting is pretty good for my ears. My son was really happy. They have nice support for the arch of your foot. Who knows? I just keep ordering shoes of different sizes and hope for the best. I had little headaches from those, they dont feel amazing in hears and they heart a little sometimes, the sound suppression dont works really well, but theyre ok Anyway, I like to think I wear a 10 in dress shoes, and this one fit perfectly. You can hit a table and the (shock) sound will be nullified nearly completely. You can go weeks without charging. Playing music (jazz, classical, electronica, and blues) all seems distant and just missing richness. I always have to put a cushion liner underneath straps like these to prevent blistering on one or both pinky toes, or put a heel liner in to make the smaller foot not fall out of the shoe.
