Abstract
An earphone includes a housing enclosing an acoustic transducer and having a front volume. The housing includes a nozzle that extends the front volume to at least an entrance of a wearer's ear canal, and a groove in an outer surface of the housing, extending at least along a length of the nozzle. A flexible ear tip is configured to attach to the housing. When the flexible ear tip attaches to the housing, the groove and a portion of an inner surface of the ear tip together form a port that acoustically couples the front volume with an environment external to the earphone.
