Compatible Radios
The MH-89A4B Comfort Loop Headset is designed for EVX-S24 radios only — it uses the connector and fit specific to that model, so it is not interchangeable with other series. If you run a different fleet, browse the full commercial two-way radios lineup, or pick a headset matched to your model: the MH-37A4B-1 Comfort Loop Headset for single-pin VX-series radios, or the P4500V Over-the-Ear Swivel Headset.
