Icom HM-165 Waterproof Speaker Microphone for IC-M34 / IC-M36 / IC-M94D Series
The HM-165 is the OEM waterproof speaker microphone for Icom IC-M34, IC-M36, IC-M93D, and IC-M94D handheld marine VHF radios. It connects via a 1 pin 4 poles screw-type waterproof connector and carries an IPX7 rating - submersion to 1 m for 30 minutes. At 127 g with a 315 mm coiled cable and swivel alligator clip, the unit stays accessible on a life jacket or jacket collar throughout a full watch.
Why Professionals Choose the Icom Speaker Mic HM-165
On a working vessel — a commercial fishing boat, a charter, or a patrol craft — the radio stays in a pocket or on a belt while the operator handles lines, equipment, or the helm. Reaching into a pocket to transmit on the IC-M34 or IC-M36 costs time and both hands. The HM-165 swivel clip positions the mic on a collar or life jacket strap so PTT is always within reach without unholstering the radio.
The screw-type waterproof connector matches the IPX7 rating of the IC-M34 and IC-M36, so the combined unit — radio with HM-165 attached — stays sealed at the same depth as the radio alone. The HM-165 is also buoyant: when connected to a compatible radio, the assembly floats, which matters on deck in rough conditions or boarding situations. The 315 mm coiled cable gives enough reach from belt clip to mouth without excess cable tangling in gear.
Third-party speaker mics for Icom marine handhelds vary in connector fit and seal quality. The HM-165 connector is designed to mate with the IC-M34 and IC-M36 jack specifically — an imprecise connector fit breaks the IPX7 seal at the radio port, which is the most common failure point for marine speaker mics. The HM-165 is the original Icom part, built to the same ingress protection standard as the radio it connects to.

FAQ
Is the HM-165 compatible with the Icom IC-M25 and IC-M73?
The HM-165 is confirmed for IC-M34, IC-M36, IC-M93D, and IC-M94D. The IC-M25 and IC-M73 use different connector configurations and are not listed as compatible with the HM-165. Using the wrong speaker mic on a marine radio breaks the waterproof seal at the connector port. Contact our team to identify the correct speaker mic for your specific Icom marine radio model.
Does the HM-165 maintain the radio's IPX7 rating when connected?
Yes. Icom designed the HM-165 with a screw-type waterproof connector that preserves the IPX7 rating of the connected radio. When the HM-165 is attached to the IC-M34 or IC-M36, the combined unit can be submerged to 1 m for 30 minutes. The assembly also floats, which is critical for man-overboard and deck operations where the radio may enter the water.
