Modern and attractive PELTOR™ X Series Earmuffs provide excellent hearing protection against a wide range of noise sources arising within both workplace and leisure-activity environments. Low-profile, lightweight design is perfectly balanced to deliver superior wearing comfort. Padded, easy-adjust, twin-wire headband is fully encased within a non-conductive material to protect against low-voltage electrical hazards (less than 440 V AC). Pivot/tilt earcups and soft, wide cushions help the wearer achieve and maintain the proper amount of pressure around the ears to ensure an excellent, highly effective acoustic seal without compromising the earmuff's snug, pleasant fit. Innovative foam earcup inserts and spacers further improve noise-attenuation performance. Cushions and inserts are removable and easy-to-replace (replacement cushions and inserts sold separately). Material(s): ABS Plastic; Ear Cushion Material: Slow Recovery High Density Foam; Noise Reduction Rate (NRR): 31 dB; Ear Muff Style: Over-The-Head.
