Have not worn them much, just tried them on to make sure of the fit. Microphone: Built-in microphone and control buttons allow you to take calls (phone call, gotomeeting, slack, skype) with the active noise cancelling. These headphones have really good sound quality for the price I got these headphones at. Etwas weiter nach vorne verlaufen ist zudem noch ein kleines Mikrofon versteckt, welches für Telefonate verwendet wird. Way better than our shoes cluttering up the floor and having a place to sit while putting them on is a big plus! DO NOT RECOMMEND I am currently on my third pair of these and will probably have to buy a fourth within a month or so. These shoes were a reasonable price they came beautifully packaged and they are very comfortable shoes i wore them with a full length dress and I kept them on from 7pm - 1pm and danced most of that time. -La comodidad (realmente no se sienten y no lastiman)Contras:- La batería-Como manos libres no suena muy bien, la persona con la que hablas escucha mucho "ruido", tu los escuchas perfecto, pero ellos a ti no. Very comfy and great sound ??????.
