ADVANCED HEARING PROTECTION WITHOUT ISOLATION
Stereo Listen-Through – We’ve found the most common issue with hearing protection is the isolation users feel when wearing them. We added Stereo Listen-Through to all of our Apex 3-Series headsets to enable users to gain critical situational awareness.
24dB NRR – With 24dB of certified NRR protection, the Apex 3-Series are ready to go where you need to be.
Personal Sound Dosimeter – Hearing protection is nothing if it’s just a guess. This is why we added a personal sound dosimeter to every Apex 3-Series headset. Know you are wearing the headset correctly and have the protection.
Active Sound Management – We manage sounds from all communication sources to ensure optimal clarity and protection. This is done with the noise canceling and auto-leveling microphone, automatic loud noise suppression, and personal sound dosimeter with automatic input gain adjustments.
