While all of these products are used to reduce irritation caused by mask loops rubbing against the ears, they have slight differences. Comfort Bands have an elastic band and a single anchor on each side of the band. They are not customizable. Ear Relievers have multiple notches for you to anchor your ear loops on. To make the mask tighter or looser, simply put the ear loops on a different notch. Ear Relievers can be customized with your logo if you desire. Ear Savers are very similar to Ear Relievers; they have multiple notches on each side to adjust your fit. However, they look slightly different because the grooves on Ear Savers are longer and look more like a half-circle. They are also customizable, allowing you to put your logo on them to create a cohesive and professional look.
