About the measurements
A-Spire Wireless and the two competitor headsets: measured in our lab, shown with 1/3-octave smoothing. The average is (left + right) / 2 in dB at each frequency.
Same clip. Five sounds.
Blast Guard has two modes. Lower the Loud pulls loud peaks like gunfire and flashes down. Footstep Enhancer lifts the frequencies footsteps live in.
Press play, then switch between the five settings. The clip keeps running, only the sound changes. Watch the spectrum and the level meter as you switch.

A flash at mid-distance ends in a whine that swallows everything you need while you can't see. Press play and switch between the two tunings while the flash rings out.
Stock tuning: the whine hits full force.

Your room. Gone.
Nobody plays in a studio. Pick the noise that sounds most like where you play, then switch Advanced Hybrid ANC on and off while the footsteps keep coming.
Someone vacuuming in the next room.
