A method of customizing the fit of a portion of an in-ear audio device within a portion of an ear includes determining a degree of sealing between the in-ear audio device and the portion of the ear and applying a voltage to at least a portion of an ear tip coupled to the in-ear audio device to selectively expand or contract the portion of the ear tip based on the determination until the degree of sealing between the in-ear audio device and the portion of the ear achieves a desired degree of sealing.
