Key Features
Receive-Only Audio
Directs all incoming messages to your ear so you can mute the speaker on your remote speaker mic and listen discreetly.
Compact & Discreet
A low-profile, surveillance-friendly design keeps communications private — well suited to security and covert monitoring.
All-Day Comfort
Lightweight construction can be worn comfortably for many hours, making it practical for long shifts and full event days.
3.5mm Jack Connection
Plugs into any remote speaker microphone that has a 3.5mm audio jack — a simple, no-fuss audio upgrade.
Compatible Radios
The Motorola WADN4190 Receive-Only Earpiece connects to any speaker microphone fitted with a 3.5mm audio jack, making it a flexible add-on across common Motorola portable setups — including CP185 and CP200d two-way radios paired with a compatible remote speaker mic. Because it relies on the speaker mic's 3.5mm jack rather than the radio's connector directly, it drops neatly into many existing commercial radio kits.
