My pot was fortunately plastic. They look nice too and the heatsinks seem pretty low profile so I dont have an issue with my CPU cooler. They look good with anything. There is no grip to your foot with this material. I feel the same way. I thought maybe I was just blind because I wasnt wearing my glasses. The fabric is not what I imagined but it fits great and the stretch makes it comfortable. Product as advertised in description. I’ve used 2 different other headphones (10-year-old Sennheiser corded through my old iPhone) and in-ear head Bluetooth buds, to listen to a specific song as a control, and these new headphones sounded considerably better. The quality of materials is in line with the 5star design creating a pair of truly premium earbuds.
