Smaller diameter, but packed in more innovation. The result is the patented Matrix, a triumph of hearing protection technology. It promises enhanced communication, safety and compliance. And forget rolling forever. Insertion is fast, and protection is instant upon proper insertion. A revolutionary, super-soft outer skin ensures comfort, and low-pressure foam does away with that plugged-up feeling. Plus, Matrix’s uniform attenuation blocks harmful noise while voice frequencies can be heard more naturally, combating worker isolation and overprotection on the job.
