But you better make sure its charging before you walk away because you might need to adjust it. However, I have read other reviews from customers saying the shoes werent comfortable. This shoe was very narrow, especially the toe strap. unfortunately they break off at the extension point: happened on one side first, (taped it as makeshift), then broke on the other side. I just dont see that many people buying it at $229+, but maybe they are. Completely ruining the listening experience. Cant win them all I guess. I powered it on, the little voice said BATTERY FULL. Having utilized Bose headsets for as long as they have sold headsets, A small fortune has gone toward replacement ear cushions. If the manufacture replaced it with metal just like the rest of it and be an awesome buy.
