The SPROM Helmet‑Mount Earmuffs are durable, helmet‑mounted hearing protectors that deliver reliable passive noise reduction with an SNR of 28 dB, helping reduce exposure to harmful sound levels in noisy work environments. They attach directly to standard safety helmets with spring‑loaded arms that ensure a secure fit and can be easily lifted and parked when not in use. Soft cushioned ear cups provide comfort for long shifts, and the tough impact‑resistant materials make them suitable for construction, manufacturing, mining, and other industrial settings.
