Abstract
Earphones intended for being worn in the ear canal (in-ear headphones) usually contain an ear pad, which the user may exchange for other ear pads of different sizes. Also earmolds, which are alternatively useable, can easily be exchanged. The ear pad or earmold can be mounted on a receptacle of the earphone. For mechanically or acoustically adjusting the frequency response of the earphone, the ear pad or earmold has at least one cavity. When the ear pad or earmold is mounted on the earphone's receptacle, the cavity is acoustically connected with the sound channel of the ear pad or earmold and is adapted for acting as an acoustic resonator, in particular as a Helmholtz resonator, in the audible frequency range.
