Motorola Solutions HKLN4604 Earpiece Microphone Ptt

Product Description

The MOTOROLA SOLUTIONS HKLN4604 is a lightweight earpiece microphone designed for use with compatible Motorola two-way radio series. It fits over either ear, making it accessible for both left- and right-handed users. The in-line microphone and integrated push-to-talk (PTT) button allow hands-free monitoring and quick keying without reaching for the radio. At 0.2 pounds, the unit adds minimal load during extended wear. This accessory is typically deployed by security personnel, facilities technicians, event staff, and trade professionals who rely on two-way radio communication during active work shifts.

The HKLN4604 is suited for light commercial and industrial environments where discreet, reliable radio communication is required. Its over-ear design stays in place during movement, and the in-line PTT button keeps the radio body secured to a belt or vest. This earpiece is a direct-fit accessory intended for use with specific Motorola portable radio series commonly found in commercial facilities, job sites, and service operations.

No tools are required to connect this earpiece. Power down or set the radio to a non-transmitting state before connecting or disconnecting the accessory jack to avoid audio feedback.
