La calidad del sonido es excelente. El artículo es súper bueno porque ya lo he comprado hacen cinco años. Same maker, same everything, just different colors. Love these shelves. I personally use mine for YouTube videos and its perfect. When I slipped them on, it fit like a glove and there were no pressure points when I walked. if they improve comfort level I lost the half of the cord to my headset that has the sound balance knob on it, so I couldn?t use it at all. After washing them (still looked funky) I decided to use my dogs teeny wire hair brush. It came well protected and in good shape.
