Claim 15:
16. An earmold having an earmold shell, the earmold shell having a first end and a second end, wherein when the earmold is worn by a user, a tympanic membrane of the user is closer to the first end than the second end, the earmold comprising:
a receiver configured to provide an audio output signal;
a receiver channel coupled to an output of the receiver and extending to a receiver opening; and
a vent channel coupled to the receiver channel through a vent port, the vent channel having a vent opening;
