I got these as a christmas present, and I'm very happy. I would have paid the $79.99 for these myself in a heartbeat. The problem with the design I had, was kind of a personal thing. I like to sleep with good music, but can't with headphones. But I sleep on my side so earphones and MOST earbuds kinda hurt, or don't work out. These, were actually very good, although I had to adjust my pillow a bit. They come with 6 different covers. Small rubber skin, large rubber skin, and foam. I use the foam ones, because they make them fit perfectly, yet you can BARELY notice them. Very good Sennheiser, I'm pleased.
