Supershieldz never fails to amaze me. These slippers are comfortable and easy to slide onto my feet. El envío muy rápido y llego en perfectas condiciones. Good for noise cancellation such as conversation. They are so comfortable. Would be better if it was announced with words like battery low. I normally love the shoes, and they last from 6-8 months. Battery timeThe units come with a usb-c charger and that is a plus and advantage in charge time and compatibility with my other devices. Great story & art by a group of upcoming stars. Bought another pair because I wore the others out--after 3 years!
