Sound is good also. This slipper met all my/his needs and then some! I normally wear a 9, but my heel was just at the stitching of the heel. It worked very well and put a great sheen in my beard and now it looks and feels soft and actually matches my hair better. be careful. I like everything else about them so much, I can overlook this one little glitch. So not fung shui. Used this in our dogs ear and the infection is gone and has not returned! Of the microphones that AT offers with traditional LDC construction this one has the largest of them all yet its one of their lowest price models. A more snug fit than the classic shape.
