Conclusion: These are the best true wireless on the market hands down in my opinion. Lasted about 2 weeks then collapsed in on the self on a dirt road. I looked at several and after comparing features, size, price and ratings. I wish they would be differentiated. Immediately took a couple hour break and tried again only to feel it again with 20 minutes. Product was exactly as advertised. I like that this has the option to go over the door or mounted on a wall. Las puse en las nintendo y nada. My Son was in a jam as his laptop adapter suddenly quit working. These bike racks have one rope pull on the front of the unit easy peasy
