Compatible Motorola Radios

This earpiece is built for Motorola SL7550, SL7580, SL300, SL3500e, SL4000, SL1K and SL1M two-way radios. It provides a discreet, hands-free audio solution for professionals who need clear, private communication during daily operations. The single-pin connector ensures a secure fit with the listed models.

Upgrade From Basic Headsets

The reinforced PU cable with Kevlar fibre and a high-cycle push-to-talk button replace standard cables that fray or fail under heavy use. The transparent acoustic tube and mushroom earbud deliver low-profile wear that stays comfortable over long shifts while keeping conversations private. A spare earbud is included for hygiene or loss.

Check Your Radio Connector

Verify that your radio uses the single-pin waterproof connector shown in the specifications before ordering. This headset will not fit multi-pin or differently keyed ports on other Motorola series. Ensure the acoustic-tube style suits your environment and that the large PTT button can be operated easily with gloves or gear.
