I have a set of the Vshape muffs that velcro on your straps to your helmet. A friend made me a pair. You could easily make a pair with warm soft fabric and velcro. In cold winter months I wear a silk balaclava that can be worn in many different ways. It wicks and keeps you warm. In the summer, I just wear a nice soft cotton bandana. I hate wind in my ears and the bandana is not bulky and protects my ears. I have head bands and sweat bands and I still prefer lightweight breathable fabrics.
