Abstract
An earpiece that substantially lacks a lower lobe is disclosed. The earpiece has a generally arcuate rib having upper and lower ends. A generally vertical rib extends substantially between the upper and lower ends of the generally arcuate rib. A lobe is formed at the upper end of the arcuate rib. No lobe is similarly formed at the lower end of the arcuate rib. Eliminating the lower lobe mitigates discomfort during use and also reduces the likelihood of tissue damage and infection.
