The battery drained too quick right out of the box. The connectivity is great, sound works really well with decent bass, ease of use when using touch commands. In retrospect, that was dumb on my part and I should have just sent it back for a new one in order to not risk voiding the warranty. I had a cheap knockoff version of these before which i really liked by the brand of outland which i cant find anywhere on the internet , and it had problems like this all the time , I was, however, able to repair it often with needle and thread and shoe goo. Se ve un poco en la foto con mi mano y los cascos abiertos. It?s like a sound card in the microphone to process your voice. Even with the glasses, they fit fine but they do move some if I tilt my head back - not a complaint, just simply stating, it doesnt affect the functionality. I love the look, and I love how it sticks to the wall. This is such a cute shoe and I WISH I could?ve given it a better review. Kinda worried when I first put them on because of negative reviews.
