I had very high expectations, but was disappointed. They surely look very nice, but are very uncomfortable to wear. In fact, my ears hurt after a few minutes. When it comes to sound, they alter the sound considerably. The high frequencies remain, but they create notches in the mids and leave all of the bass. Sure, you feel the bass, but still. Since I was disappointed by the sound and my ears hurt, I simply went back to the good old cotton. Much better, and it saves me money.
