With 600 - ohm impedance, the HC - 7 is great for clear speech.

Using the Heil Sound PRO7 - ICBK headset is easy. First, adjust the ear pads to fit your ears comfortably. The foam - gel ear pads reduce outside noise well, so make sure they're properly in place. To balance the sound between the left and right earphones, use the audio balance control. If you're having trouble picking up weak signals, try using the phase - reversal switch. When a second operator wants to monitor the audio, just plug their headphones into the monitor jack. For the microphone, it's ready to use right away, and it'll give you clear speech due to its good frequency response. Now, for some notes. Don't expose the headset to extreme temperatures or humidity. When not in use, store it in a dry place. If the ear pads get dirty, you can wash the cotton ear pad covers. And check the cables regularly for any signs of wear and tear. If you need to replace the cables, make sure to use the military - grade ones that are suitable for this headset. That way, your headset will keep working great for a long time.
