Very short battery life Sure enough, my neck/shoulder pain had returned as well. I would personally suggest using a wire keycaps puller. La música electrónica suena muy bien gracias a los potentes bajos. Im hoping they hold up a few years, but they are as cheap as you expect given the < $40 price tag. If I were at a store looking at this, I would have tried a different piece or not buy it at all. buen producto para el precio, contar que el cable no es de textura tradicional, tiene una capa de goma que ayuda a su duración, en conclusión buen producto en relacion precio-calidad It sounded like when you have a blown speaker in a car. Very sturdy with excellent sound quality. May get a few more to connect with camping for scary movie night.
