La batería tiene una duración "decente" (3 o 4 horas de reproducción continua) el problema es que, a diferencia de otros dispositivos bluetooth (otras marcas), estos audífonos no entran en modo reposo si no reciben ninguna señal de audio después de cierto tiempo, cosa que provoca que la batería se descargue a menos que recuerdes apagarlos. As soon as I opened the box I knew that wasnt the case, these feel amazing on my head! But seems to do its job. Very comfortable and helped sort out my very sore heels. Again, overall a great head unit. Part of my foot was hanging a tiny bit over the edge of the marvellous, cushy, leather footbed. Ive been in homes where there are a jumble of shoes piled haphazardly inside the door, which I dont like. Se obtiene lo que se describe en los detalles, la funda de carga no parece de buena calidad. Not fun at all. I selected these because of the price and made note of one of the other reviews explaining the cross bars can only be installed from the rear and to invert the pieces that go into the channel.
