Heil BM-17S Dynamic Headset
The speakers used in the BM-17 are very sensitive and don't require much AF drive 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. This 500 ohm dynamic element will work on most amateur radio rigs requiring a Low-Z input impedance (usually between 150 ohms and 4k
ohms). Radios requiring a high impedance input of 10k to 30k ohms will require the use of an XT-1 impedance matching transformer. The BM-17-Dynamic has an operating frequency response of 120Hz - 10 kHz.
