With low profile earcups they provide a snug fit without sliding off your head.

The ear muffs automatically shut off when the audible range level reaches 82dB. This prevents hearing damage from dangerous pop-ups and snarls. For added safety the earmuffs use a circuit board inside the ear cups that automatically stops active noise from reaching the ear. Laws passed requiring earmuffs in amplification the muffs automatically cut-off the earcups after 4 hours to preserve battery life.
