An eartip includes a compliant portion that forms at least a portion of a sound channel, and a wax guard that is supported in the compliant portion and is disposed within the sound channel. The wax guard includes a porous, planar body that permits the passage of acoustic energy but inhibits the passage of cerumen therethrough, and a retention member. The retention member is arranged along an outer edge of the planar body and in direct contact with the compliant portion. The retention member includes a plurality of openings. A compliant material that forms the compliant portion permeates the openings in the retention member to assist in retaining the wax guard in the compliant portion.
