Heil BM - 17 Dual Headset (Single Sided + IC Electret)

The Heil BM-17 Single-Sided iC Electret Headset combines lightweight comfort, flexible operation, and exceptional audio performance for amateur radio operators using compatible Icom transceivers. Newly redesigned for enhanced versatility, the BM-17 features a swivel-mounted boom arm that can be positioned on either the left or right side, allowing operators to customize the headset to their preferred operating style.

Its single-ear design keeps one ear open to your operating environment while delivering clear receive audio through a highly sensitive, low-distortion speaker. With a speaker frequency response of 200 Hz to 5 kHz, the BM-17 provides excellent intelligibility for voice communications while requiring minimal AF drive from your transceiver.

Equipped with Heil's iC electret microphone element, this headset is specifically engineered to work with the low-gain microphone audio circuits found in select Icom radios. The iC element delivers outstanding voice clarity and wide audio response, operating from 35 Hz to 12 kHz with fixed -3 dB points at 100 Hz and 12 kHz. The microphone offers a sensitivity rating of -57 dB at 600 ohms output centered at 1 kHz for natural, articulate transmit audio.

The iC electret element requires +5V DC bias power supplied by the radio and must be used with the appropriate adapter cable (sold separately). Please consult your Icom radio manual for microphone bias power settings and compatibility information.

Designed for long operating sessions, the BM-17 features replaceable acoustic foam ear pads and a padded headband with an internal stainless-steel support band that can be gently adjusted to achieve a personalized fit. The microphone terminates in a red 1/8" mono plug, while the headphone connection uses a black 1/8" stereo plug. A 1/8" to 1/4" headphone adapter is included for added compatibility.
