A triumph of hearing protection technology, Matrix has a smaller diameter than most other foam plugs but its packed with more innovation. 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.
