Sordin 10251224 Earmuff Nrr 25 Db Medium Black Headband

Product Description

The SORDIN 10251224 is a passive over-the-ear hearing protector designed for trade and industrial environments where sustained noise exposure is a concern. Built on a foldable headband platform, this earmuff delivers a Noise Reduction Rating (NRR) of 25 dB and a Single Number Rating (SNR) of 28 dB, placing it in the medium attenuation category. The cups and cushions are constructed from polyurethane and ABS materials for durability and comfort during extended wear. No batteries are required. Licensed HVAC techs, electricians, plumbers, welders, and general construction trades use this type of protector during equipment operation, grinding, and other high-decibel tasks.

The 10251224 is suited for confined space work, welding operations, construction sites, mining environments, and oil and gas facilities. The foldable headband design makes it practical for workers who move between loud and quiet zones throughout a shift. The one-size-fits-all fit and left-right symmetric cup design simplify deployment across crews. This protector meets ANSI S3.19-1974 attenuation standards, which governs how NRR values are measured and reported.

Key Features

• Meets ANSI S3.19-1974 approval standard

Compatibility

Designed as an OEM-style replacement or direct-use hearing protector for confined space, welding, construction, mining, and oil and gas applications requiring medium-level passive noise attenuation with a standard headband mount.

Installation Notes

No installation is required. Position the headband over the crown of the head and seat both earcups fully over the ears to form a complete acoustic seal. Inspect cushions regularly for cracks, hardening, or compression set, as degraded seals reduce effective attenuation. Replace the protector when cushions no longer conform properly or when the headband loses clamping tension.
