HKLN4477-HKLN4601 Single Wire Surveillance Earpiece
Single Wire • Inline PTT & Mic • Clear Acoustic Tube • Rubber Eartip • Black
The HKLN4477-HKLN4601 Single Wire Surveillance Earpiece is a discreet, professional audio accessory for teams that need to communicate quietly on the job — retail, hospitality, and security. This single-wire earpiece combines an inline microphone and push-to-talk button with a clear acoustic tube and rubber eartip, giving you full transmit and receive capability while staying low-profile. Pair it with a compatible Motorola business two-way radio for all-day, comfortable discreet communication.
Who It's For
Built for retail associates, hotel and event staff, and security personnel who need hands-near, eyes-up communication without an obvious headset. The HKLN4477-HKLN4601 single wire surveillance earpiece is a classic single-wire kit — for a heavier-duty option with a separate inline mic and PTT, see the HKLN4599 D-Style Earpiece, or the simpler HKLN4604 Earpiece with PTT.
