Great product for the proce I was a little worried these phones might be bass-heavy, but they are quite balanced. I found they fit true to size. Company does NOT stand by their product. I tested the Xelastec tips and ML works best for my left ear and MS/M for my right ear. I had Sambas before that lasted years. Dicen que con iPad y iPhone el problema debería desparecer según el protocolo de Bluetooth que utilizan sendos modelos, pero no es cierto. They’re warm without making your feet too warm if that makes sense too. I have attached a photo of the heel of the slipper to show how my foot slid while wearing them, and wore down the side of the heel. Very confusing to set up took forever to realize I had icons saved off screen effecting some controls
