The ProMicro is a lightweight headset with one or two open speakers. The flexible boom microphone is equipped with the new Heil HC-6 dynamic element, which offers a wide and clear modulation. For DX or contest operation most recent radios offer an equalizer to influence the modulation to your needs. Due to the light contruction this headset is perfect for long operatiuon with getting tired. The Heil ProMicro Headset is available with one or two speakers. The one-sided version is useful in situations where you need to hear other acoustic information from around you, for example tzhe whining dog who needs to go outside very urgently.
With various adaptor cables this headphone can be used on nearly any radio. For older Icom transceivers (before IC-756Pro) we recommend the Traveler headset with dynamic Icom mic element. For operation of the ProMicro an adaptor cable AD-1-xx and a PTT switch is required additionally.
