Wish a right angle plug one one end was available. They are incredibly comfortable other than there is a piece of metal right in the middle for a bottle opener. En relación con el costo son excelentes, la duración de la batería es buena ya que el cargador da aproximadamente a 3 cargas al 100% de los auriculares y la carga de cada uno de ellos es aproximadamente de 8 horas lo que es muy bueno, respecto del uso con llamadas no tengo inconvenientes con el micrófono y la calidad de audio no es la mejor pero si es bastante buena. In full disclosure, I did return this device and I purchased the newer "E" version of the Huawei Matebook (2017 model) that has an Intel Core m3-7Y30 processor with 4GB RAM after exhaustive research and using this machine that has an Intel m5-6Y57 processor and 8 GB RAM for several days. UPDATE July 2: Have had this hat a month, wear it every day in the sun and it has FADED. 5 W/KG while I performance with the same cadence. The seat does not have soft padding. When they work. I got to explain to my kid who he was and took her to see him in action in the theaters. So, this gives me a little peace of mind by providing lightweight security.
