The Heil Pro 7 is an aviation-style headset designed for amateur radio use in high-noise environments. The specially designed foam-gel ear pads provide 26 dB outside noise reduction and provide exceptional comfort. A true dual-channel, stereo headset, the Pro 7 features an audio balance control that allows the user to adjust the level of the left earphone to match the right. A unique phase-reversal switch greatly helps the listener “dig out” weak signals. The latest version of the Pro 7 features a monitor jack, which allows a second operator to plug in headphones and monitor audio.
The flexible gooseneck mic boom on Pro 7s may be rotated for use on either the right or left ear. Two production versions are available, depending on whether you require a dynamic or electret microphone element. However, the microphone elements are easily interchangeable, allowing you to swap out elements to be used with different rigs or for contesting or DX purposes. Check out the different element options here. The Heil Pro 7 headsets will work with current AD-1 series adapter cables and accessories. See our Adapter Selector to find the right cable for your radio.
