How does the headset protect my hearing?

This headset is certified with EN 50332-2 and compliant with G616 to protect ears from acoustic shock and long-term sound exposure.

It has the loudness that is always capped at 100 dBA.

On the Logi Tune app, you have an option to enable additional hearing protection for particular circumstances:

Anti-startle protection is to avoid sudden high-pitched sound during a call.

If you are using a headset for calls all day long, Noise exposure control can help monitor the average daily noise levels in a call and ensure they do not go beyond the time-weighted average of 85dBA.
