Compatibility warning
The PMLN8364 is a rubber replacement sleeve only. It does not connect directly to a two-way radio and does not include the PMLN8337 earpiece, removable earhook, cable, microphone, push-to-talk button, speaker, or radio connector.
Radio compatibility is determined by the complete PMLN8337 earpiece—not by the PMLN8364 sleeve itself.

When attached to a compatible Motorola PMLN8337 earpiece, the PMLN8364 can support radio systems involving models such as:
- Motorola APX N30
- Motorola APX N50

Why Replace Your PMLN8337 Rubber Sleeves?
Earbud sleeves experience regular contact with skin, perspiration, dust, and workplace contaminants. Frequent insertion and removal can eventually stretch or damage the material.
Replacing the sleeve can help:
- Restore a secure fit
- Improve comfort during long work shifts
- Reduce unwanted movement during physical activity
- Extend the usable life of the PMLN8337 earpiece
- Provide separate sleeves for different users
- Improve hygiene in shared-equipment environments
- Reduce the cost of replacing an otherwise functional earpiece
The 25-pack is especially practical for radio fleets in which several employees use the same model of earpiece.
