These look good (I ordered 2) and are easy to find a home for due to their smaller size. While Id been hopecful that theyd be comfortable, I had a bad feeling that Id try them on and end up leaving them at home so I could wear sneakers instead. The microphone quality is good and they are well made. I had to send these back. It is confirmed swabs of that which is most likely to be cotton. The microphone is loud and clear, good background noise cancelling. These are the only pair that have such a hard surface for your foot. And think about the height between the arch and the ankle. I also like the small case. My feet are big and the slippers fit but I can’t grt my foot into it.
