摘要:
Apparatus and associated methods may relate to a unitary body having a hardness of between 20 and 35 according to the Japanese Industrial Standards (JIS) and adapted to be removably inserted into the canal 10 of an ear. In an illustrative example, the body may include a central portion between an adapter portion disposed at the proximal end of the body to couple an audio signal from an audio signal source to the central lumen. The retention portion may be disposed at a distal end of the body along a distal end axis. When inserted in the ear canal, the retention portion may be adapted to engage the canal wall between a prominence and the eardrum membrane with comfort for extended periods of time, including during physical activities, without falling out of the ear. Some embodiments by be packaged as a kit containing pairs in a range of predetermined sizes.
