Be sure the radio is within range of its base station.
The wireless radio connected to the headset might be out of range of its base station. This can cause interference, poor or intermittent microphone or headphones. Try moving the radio closer to its base station.
Turn off the Acoustic Noise Reduction.
In high-noise environments or when speaking too loudly into the microphone, sound passing through the microphone can become distorted since the signal is also boosted by the active electronics in the headset
Turn off the power switch to disable ANR and use the headset passively. If the issue is resolved, use the headset passively until volume levels near the microphone are reduced

Schließen Sie ein weiteres Paar Kopfhörer an das Audiogerät an, um herauszufinden, ob das Problem am Gerät oder an dessen Einstellungen liegt.
Check to see if the sidetone can be heard clearly.
If there is no problem hearing the sidetone then the issue is not with the headset. Check the radio settings
