The worst thing I have ever had to do with my dog in the morning when it was below 30 degrees was my ears and the back of my head being uncomfortably cold. These ear warmers are perfect for just that purpose. They don't fold perfectly evenly, so they look very noticeable in a jacket pocket. I can still hear fairly well with them, but there is some damping so I can't hear deep sounds or voices. Overall I am very happy that I bought it.
