I bought the MIFULGOO Women’s Ponytail Headband Ear Warmer Sweatband in the charcoal-gray color. My ears easily get cold which causes a piercing pain in my eardrums and head even in the upper 50s or low 60s Fahrenheit-- especially when it is windy. This sweatband covers my ears adequately and holds my headphone buds in place while running. I have a medium-sized woman's head shape and I debated on ordering the larger black one since my face is more comfortable in men's eyewear. This regular-sized one is just right, not tight and not loose.
