By picking up the voice from within the head, our SonX allows workers to wear their protection, and communicate with their colleagues: in the loudest of environments. Because all our devices are connected to the cloud, they improve in functionality through software updates and provide actionable data on worker hearing health. The creation SonX is the results of 15 years of investment and very deep market knowledge and a breakthrough for these workers.



Clear speech in noise no longer a problem

Active hearing protection that adapts when you need it most


In-ear microphone picks up your voice from directly inside your ear canal. De-noising software removes background noise.
Intelligent software measures and adapts the amount of protection you need; whether talking to coworkers, in and out of the office, sudden noise, or just the high decibel levels you deal with every day.

Count on connected communication 


Communication in up to 105 dB(A)
Push-to-talk with 4 channels Bluetooth connected radio*

Feedback from environment improves work output, lowers stress and accidents, and creates a comfortable workplace. Low profile in-ear earpiece design provides outstanding 360-degree situational awareness. You’ll have peace of mind knowing that you are safer because you can now hear warnings and other danger signals, from any direction.

No need to shout

Dual microphones (internal & external) with in-ear speakers allow you to speak in normal tones lowering stress and fatigue.

Set it and forget it

Focus on the task at hand instead of fussing with your comms device. SonX lightweight design has your comfort in mind. Wear it multiple ways, SonX is compatible with your safety glasses and other personal protection equipment. Big buttons and simple interface make it easy to use the push-to-talk. Tangle-free cables can be fastened close to the body to ensure you can work in tight spaces without worry.

Discreet comfort

Discreet and lightweight earpieces weigh less than 4 grams. High density replaceable Comply™ foam tips shape to ear canal. Ergonomic adjustable ear hooks are removable and replaceable, secure earpieces and minimizes cable noise.


Get the flexibility you need to manage sound levels

  • Need to speak to others who aren’t wearing hearing protection and want to stay protected?

  • Do you regularly move from quiet office spaces to a noisy factory floor?

  • Do you work outside or deal with extreme noise changes?


We often need to manage a wide range noise levels at work. SonX ensures you are always aware of your surroundings: select the quiet comfort of Isolation Mode or switch to Transparency Mode when you need to hear more around you. Let SonX take the wheel with Auto Detect Mode, switching from Isolation and Transparency as needed. No matter what setting, you are already protected.
