#MarseeOneX I received these headphones free to give my opinion and are beautiful are very good material very easy and simple to use and connect and feel very comfortable in the ear. The audio is great as it is heard loud and very good quality. very fast charging and the charge lasts a lot. I am very happy with this product I include a manual about replacement plugs and a USB cable for charging. Ecxelente quality.
