What is the Motorola PMLN6536 Surveillance Earpiece?
The Motorola PMLN6536 is a two-wire surveillance kit for Motorola CP-series and Mag One commercial two-way radios that use the Motorola 2-pin connector. It pairs an in-ear earpiece fed by a clear, quick-disconnect acoustic tube with a separate wire that combines an in-line microphone and push-to-talk (PTT) button. Its primary function is to let a user monitor radio traffic discreetly and transmit hands-near operation without a speaker microphone broadcasting audio aloud.

What's in the Box
- One earpiece wire terminating in an in-ear earpiece fed by a clear, quick-disconnect acoustic tube and a rubber eartip
- One separate wire combining the in-line microphone and the push-to-talk (PTT) button
- A 2-pin connector that plugs into the radio's accessory port
The acoustic tube and eartip are replaceable, so the tube assembly can be swapped without replacing the entire kit.
Who This Product Is For
A two-wire surveillance kit separates listening from transmitting and keeps received audio inside the user's ear rather than playing it through a speaker. That makes the PMLN6536 a fit for environments where audio privacy, low profile, or quiet operation matters more than the convenience of a clip-on speaker microphone.
Common deployments include:
- Security and loss prevention — retail security, event security, and venue staff who need to receive instructions without bystanders overhearing radio traffic.
- Hospitality — hotel front desk, valet, and management staff who communicate on the floor while maintaining a quiet guest-facing presence.
- Public-facing operations — casinos, museums, and theaters where overt speaker-mic audio would be disruptive or undesirable.
- Executive protection and plainclothes roles — situations where the microphone and PTT need to stay concealed under clothing while remaining accessible.
It is less suited to high-noise industrial settings, where a heavy-duty headset or noise-canceling speaker microphone usually performs better, and it does not support VOX (voice-activated transmit), so every transmission requires a manual PTT press.
Key Features
- Two-wire design that separates the earpiece wire from the combined microphone/PTT wire.
- In-ear earpiece fed by a translucent acoustic tube for a low-visibility appearance.
- In-line microphone and in-line push-to-talk button on a single wire that can be routed under clothing.
- Replaceable, quick-disconnect acoustic tube and rubber eartip.
- Motorola 2-pin connector for CP-series and Mag One commercial radios.
- Core IMPRES audio support.
- Does not support VOX; transmissions are made by pressing the PTT button.
Radio Compatibility
The PMLN6536 uses the Motorola 2-pin connector found on CP-series and Mag One commercial radios. Models commonly cited as compatible include the Motorola CP100d, CP110, CP125, CP150, CP185, CP200, CP200d, Mag One BPR40, GP300, P1225, and PR400. Because connector styles can vary across radio generations, confirm that your specific radio uses the 2-pin accessory connector before ordering.

Frequently Asked Questions
What is the Motorola PMLN6536?
The Motorola PMLN6536 is a two-wire surveillance earpiece kit for Motorola CP-series and Mag One commercial two-way radios. It has an in-ear earpiece connected to a clear acoustic tube, and a separate wire that carries an in-line microphone and an in-line push-to-talk (PTT) button. It lets a user listen to radio traffic privately through the earpiece and transmit by pressing the PTT button.
Which radios is the PMLN6536 compatible with?
It connects to Motorola radios that use the 2-pin commercial connector, which includes CP-series models such as the CP100d, CP125, CP150, CP185, CP200, and CP200d, as well as Mag One BPR40 and related models like the GP300, P1225, and PR400. Because connector types differ between radio families, verify that your radio uses the Motorola 2-pin accessory connector before purchasing.
Does the PMLN6536 support VOX (hands-free transmit)?
No. The PMLN6536 is not VOX-capable. Every transmission is made by pressing the in-line push-to-talk button. If you need hands-free voice-activated transmit, you would need a different accessory and a radio configured to support VOX.
Is the acoustic tube on the PMLN6536 replaceable?
Yes. The acoustic tube is a replaceable, quick-disconnect component, and the rubber eartip can also be replaced. This allows the tube assembly to be swapped for hygiene or wear reasons without replacing the entire kit.
What is the difference between a two-wire surveillance kit and a single-wire earpiece?
A two-wire kit, like the PMLN6536, routes the earpiece on one wire and the combined microphone and PTT on a separate wire, which makes it easier to conceal the microphone and PTT under clothing while keeping them accessible. A single-wire earpiece combines all functions on one cable, which is simpler but offers less flexibility in how the microphone and PTT are positioned.
Does the PMLN6536 broadcast received audio out loud?
No. Received audio is delivered through the in-ear acoustic tube rather than an external speaker, so radio traffic stays private to the user wearing the earpiece. This is the main reason surveillance kits are used in security, hospitality, and other public-facing roles.
