After 15 years of investment from our team engineers, acousticians, audiologists, and developers we are pleased to announce the latest innovation in hearing protection technology: SonX. Using technologies that have been extensively tested in laboratory conditions and in the field, it offers advanced hearing protection, in-noise communication, and active hearing health tracking of worker safety.





Active hearing protection
Low profile earpiece
Outside microphones pick up ambient noise to assess your exposure levels.
Wireless data
Protection monitoring
Remote management
TeamLink worker app & admin dashboard


High noise communication up to 105 dB(A)
Person-2-Person communication
360-degree situation awareness
Get clear communication with in-ear microphone while denoising algorithms remove background noise. Inside microphone also measures your personal attenuation rating (PAR).

SonX Fit-Test

Ensures you are properly fitted at all times, indicating what ear (or both) needs to be re-fitted.

  • Verifies if SonX is installed correctly (visual & audio prompts)

  • A great team training tool to reinforce good H&S procedures

  • Compliant with the new ANSI S12.71 “Fit Test” 2018 standard

Level-dependent hearing

Adjusts to worker’s environment. SonX' built-in auto protection mode switches from passive or active protection based on ambient noise conditions. 


You are always ready for unanticipated loud sounds with fast impulse noise clipping.


Improve worker safety

Reduce accidents and lower the risk of errors by misunderstanding with
SonX In-Noise Communication.

Boost teamwork 

Improve teamwork and productivity through sustained communication. On-site training can safely be done in noise. Push-to-talk 2-way radio communication with team-assignable radio channels and color coding light.


  • Range: line of site 65 feet, obstructed 32 feet

  • One-to-one or one-to-many

  • Proprietary denoising algorithm for communications in noise levels up to 105 dB(A)

  • Bluetooth™ smartphone connectivity (fall 2018)


TeamLink protects hearing before there’s a problem

If a worker is not protected, management knows and can correct the problem. SonX offers proactive smart hearing protection with wireless data capture. Worker and management settings provide insight with detailed reporting.


  • Data for a healthy retirement

  • Insurance cost reductions

  • Improved Healthy & Safety programs

  • Accident reduction

  • Worker safety gateway


TeamLink provides daily vital safety and health details: Noise exposure levels, regular automated left and right PAR (Personal Attenuation Rating) tests throughout the worker’s shift (compliant to ANSI S12.71 standard), in-ear dosimetry and ultimately, personalized hearing augmentation features. The goal is to enhance existing Hearing Loss Prevention Programs and eventually reduce, if not eliminate, claims for NIHL.



Natural sound

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 warning 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.


Voice pick up directly from inside your ear canal, not your mouth


Perfect protection pairing for wearing respirators, hoods, full facepieces, and protective suits. Behind the acoustical seal of SonX earpiece is your in-ear microphone and speakers – clear communication directly from inside your ear canal, not your mouth. There's no need to shout or remove protective gear and risk exposing yourself. Low profile and lightweight, SonX has no external microphones to mess with, and does not interfere with your safety equipment.


Do your training where it counts

Maintain job competencies out of the classroom and on the shop floor. Work in-noise, directly on the very equipment you need instruction.


Less downtime 

Lower the need for simulations, spend less time in the classroom and get real-world competency training when wearing SonX for your on-the-job training. Great for group training or one-on-one.
