Everyone's ears are different. Women's ear canals tend to be shorter and narrower than men's. We've selected earplugs which we consider to be most suited for those who need them for sleeping and to combat snoring. The colours are chosen by the manufacturer, not by us. Manufacturers are idiots sometimes.
* and people with smaller ear canals. However you identify, if your ear canals are small, these earplugs are for you.
