It has fantastic treble, decent mids, and annoyingly soft bass. I contacted the company and they sent a response to watch the video on their site. I added a star for quick service to replace the faulty pair. I would have been happy with a replacement for the defective part, but they were unresponsive to that also. The company contacted me, discussed my concerns and made suggestions on how to fix them. These socks are 16 bucks a pack. The sound is really crisp and clear. The sole is thick enough to keep the sides of the slipper up off any wet surfaces including wet grass if you find yourself walking across it for some reason. Super comfy even in the heat. They are not spongy they are the all rubber that has zero cushion anywhere!
