Protection
The best hearing protection in the world cannot protect if it is not tted properly. Using the On Demand
Earpiece Fit Test you can verify the t and protection level. If not tted properly, warning signals will alert you.
SonX ensures you are always correctly tted, always protected.
On Demand In Noise Fit-Test
Ensures you are properly tted at all times, indicating which ear (or both) needs to be re-tted.
Level dependent hearing with pass-through mode
Acoustically transparent when used in a quiet environment. SonX’ built-in auto protection mode
switches from passive or active protection based on ambient noise conditions.
Impulse noise protection
You are always ready for unanticipated loud sounds with impulse noise clipping.
Communication
A person who cannot communicate properly is not fully eective. A person who cannot hear is not safe. When
in active mode, SonX is designed to ensure you can communicate in high-noise environments while keeping
your hearing protected. In-ear earpiece microphones allow clear radio communication, without the aid of an
external device. Furthermore, built-in short-range radio allows you to talk without removing your protection
while in high-noise environments. Should you step into a quieter area, your SonX device will enter passive
mode. In passive mode, you can have a conversation all the while keeping your hearing protection in.
