Swivel Earpiece for Two-Way Radio

The Plantronics HKLN4604 is a wired in-ear headset designed for Motorola two-way radios. It delivers audio directly into the ear through a soft rubber C-ring earpiece. An in-line push-to-talk button and volume control allow hands-free operation. The unit is compatible with Samsung and iPhone 7 devices per the supplier data.

Retractable Cable with In-Line Controls

A retractable cable stores cleanly and extends to the working length needed on shift. Two in-line cable clips secure the wire to clothing, reducing snag risk during movement. The 32 ohm impedance matches standard radio outputs without extra amplification. The headset weighs 0.05 pounds and requires battery power for the microphone circuit.

Replaces RLN6423 for Motorola Users

This part number HKLN4604 supersedes the earlier RLN6423 model for existing Motorola radio fleets. The upgrade is worthwhile when the original earpiece cable has frayed or the C-ring has lost its grip. It is not suited for users needing wireless freedom or a boom microphone for high-noise environments.

Questions about this item

What connector standard does the HKLN4604 use, and what does it limit?

The earpiece connects through a wired interface with in-line PTT and volume control, limiting use to Motorola two-way radios that accept this plug type.

What physical space and mounting does the HKLN4604 require?

It weighs 0.05 pounds and measures 14.33 in wide, 12.83 in high, 9.06 in deep; the soft rubber C-ring hooks over the ear and two in-line cable clips secure the cord.

How is the HKLN4604 installed, and which step is often missed?

Plug the connector into the radio, hook the C-ring over the ear, then fasten both in-line cable clips so the PTT and microphone stay positioned near the mouth.
