A low-profile earbud designed for surveillance and security roles where you need to listen without drawing attention.
Simple & Lightweight
No batteries, no controls — just a clean, lightweight earbud that plugs in and works, keeping your kit minimal.
3.5mm Connection

Compatible Radios
The Motorola AARLN4885 Receive-Only Earbud is an accessory for remote speaker microphones — it plugs into the 3.5mm earphone jack on the speaker mic rather than into the radio directly. It is commonly used alongside Motorola CP185 and CP200d speaker-mic setups and works with any Motorola speaker microphone that has a 3.5mm audio jack.
Because compatibility depends on the speaker mic rather than the radio, confirm your accessory has a 3.5mm earphone port before ordering. Browse our full lineup of commercial two-way radios and audio accessories, or contact our Canadian team to match the right earbud to your gear.
