After charging overnight, I get about 4 to 5 hours of continuous listening until the rechargeable battery runs down. This is an adorable pair of shoes BUT they zip up in the back and the zipper is almost impossible to use. On testing, could barely hear anything unless the mic is up to your mouth and has to be aiming straight at you. There is a lot to like about these earphones, and I hope it lasts! Granted i just received them today but omg. Sound is amazing. En general los recomiendo ampliamente. Fies auch: um nun zwischen den Geräten zu wechseln, muss Bluetooth auf dem zuletzt gekoppelten Gerät deaktiviert werden, damit die Verbindung wirklich der jeweils andere bekommt. He is a good boy otherwise. I played golf on a windy day and never had issues hearing the music (or my partners cuss).
