## Abstract

In embodiments of the invention, the invention comprises a light tip cable including a cartridge assembly affixed to a medial end of the cable, the cartridge assembly including an emitter housing where the emitter housing includes an opening at a medial end of the housing and a flange at a lateral end of the housing. In embodiments of the invention, the cartridge assembly includes a light emitting element in the housing extending to the opening, retention features covering at least a portion of the housing, including the flange, the retention features comprising a lateral face and a lobe and at least one load bearing strand extending from the cable to the emitter; and electrical connectors extending from the cable to the light emitting element.

## Claims

### Claim 1

A replaceable ear tip comprising:
a cartridge cavity including an emitter cavity and at least one retention groove lateral to the cartridge cavity;
a first compressible retention ring between the emitter cavity and a first retention groove;
a second compressible retention ring lateral to the first retention groove; and
a stabilizer ring attached at a lateral face of the second compression ring.

### Claim 2 (depends on 1)

A replaceable ear tip according to claim 1, the replaceable ear tip further comprising:
an acoustic vent extending from a lateral to a medial end of the replaceable ear tip.

### Claim 3 (depends on 1)

A replaceable ear tip according to claim 1, the replaceable ear tip further comprising:
at least one catch ring on a medial surface of the first or second compression ring.

### Claim 4 (depends on 3)

A replaceable ear tip according to claim 3, the replacement ear tip further comprising:
a first catch ring on a medial surface of the first compression ring; and
a second catch ring on a medial surface of the second compression ring.

### Claim 5 (depends on 1)

A replaceable ear tip according to claim 1, the replaceable ear tip further comprising:
at least one bevel on a lateral surface of the first or second compression ring.

### Claim 6 (depends on 5)

A replaceable ear tip according to claim 5, the replacement ear tip further comprising:
a first bevel on a lateral surface of the first compression ring; and
a second bevel on a lateral surface of the second compression ring.
