Abstract
In an aspect of the invention, a sealed earphone is provided with a nozzle, the earphone configured to be positioned in a user's ear so that the nozzle extends toward the ear canal of the user. The earphone includes a driver mounted within a housing of the earphone, the driver including a sound port acoustically sealed to the nozzle. In an embodiment, the driver may include an acoustic port that directs sound into an acoustic enclosure so as to modify the frequency response of the earphone. The earphone may include a fastener that removably mounts the nozzle to the housing so that the nozzle may be readily removed and cleaned or replaced.
