An earbud coupling has a rear portion forming an earbud mount ( 14 ) that easily attaches to a hemispherical earbud ( 12 ), and has a front portion forming an in-ear mount ( 16 ) that can be pressed into a person's ear canal to hold the coupling to the person while blocking environmental noise. The earbud mount includes a tapered elastomeric sleeve ( 50 ) with an internal groove ( 62 ) at its rear end. The earbud mount rear end can be expanded to fit around the periphery of the earbud front end to securely attach to the earbud. A plurality of different in-ear mounts or tips can be provided that each can be attached to the front end of the earbud mount, including an in-ear mount ( 100 ) that consists of a single integral elastomeric member with at least one flange ( 205 ). The earbud mount and in-ear mount can be connected by a shaft ( 130 ) with pair of projections ( 132 ) on one of the mounts that is inserted into a hole ( 136 ) with slots ( 140 ) of the other one and turned.
