An earpiece that substantially lacks a lower lobe is disclosed. In one example, the earpiece can have a generally arcuate rib having upper and lower ends. A lobe can be formed at the upper end of the arcuate rib. No lobe is formed at the lower end of the arcuate rib. An extension can extend from the earpiece and can be configured to extend into the ear canal. Eliminating the lower lobe mitigates discomfort during use and also reduces the likelihood of tissue damage and infection. The extension can enhance communication of desired sound, e.g., from a two-way radio, to an eardrum while mitigating communication of undesirable ambient noise to the eardrum. Other implementations and related methods are also disclosed.
