Heil Sound BM-17D-DYN Lightweight Dual-Sided Boomset with Dynamic Element

The BM-17 is a lightweight single-side or dual-side headset designed for Amateur Radio use. To accommodate different radio setups, the BM-17 is available with either a BM-17-Dynamic element or a BM-17-iC electret element. The speakers used in the BM-17 are very sensitive and dont require much AF gain from the transceiver. The frequency response is 200 Hz - 5 kHz with very low distortion. The ear pads are replaceable acoustic foam. The BM-17-Dynamic headset uses the BM-D dynamic element designed specifically for communications use in Ham Radio. This 600 ohm dynamic element will work on most amateur radio rigs requiring a Low-Z input impedance (usually between 150 ohms and 4k ohms). The BM-17-Dynamic has an operating frequency response of 120Hz - 10 kHz.
