Earmuffs - Hearing Protection

 

Elvex Equalizer™, HB-2000

Equalizer ear muff, HB-2000, with optional storage bag, SGB-30

Elvex Equalizer muff may be the ultimate compromise between comfort and performance. It offers most of the features of the SuperSonic muff, but has a lower profile ear cup, and excellent comfort. Most environments do not require maximum attenuation, and the Equalizer maximizes speech communication in moderate noise environments.

Additional features of the Equalizer muff:

    27 dB Certified NRR to ANSI S3.19-1974
    A flexible inner headband aligns automatically to the shape of the head
    Fully dielectric construction
    Pressure equalizing headband provides even fit and seal for a wide variety of facial configurations and sizes
    SuperSeal™ ear cushions provide outstanding seal and comfort
    A flexible suspension allows muffs to automatically adjust to facial shape
    A dielectric construction for environments with exposure to high voltage situations
 
Convenient foldout rest position Standard earmuff rest position
