3M™ Peltor™ Alert™ Headset with FM

The 3M™ Peltor™ Alert™ headset is designed for use in tough and noisy environments. With level dependant these ear defenders combine comfort and wearability with effective protection from harmful noises within your workplace.


These hearing protectors have an SNR (single number rating) of 30 decibels (dB) and built-in FM radio receiver. Powered by two AA batteries, which provide approximately 70 hours of operating time.

Rugged Design

Alert hearing defenders are dependably safe and ruggedly built to cope with everyday wear and tear in harsh environments. Whatever the conditions you face at work, whether extreme heat or cold, damp environments or out in the rain, underground or in a generally noisy environment, you can rely on these ear defenders to keep on working and keep you safe.


The Alert hearing protectors consist of rigid cups with sort plastic cushions that seal around the ears to reduce noise. The wide sealing cushions are filled with a combination of fluid and foam, for extra comfort and optimal sealing. The low profile ear cups have a generous amount of space inside to allow the ears to breathe, meaning they can be worn comfortably for longer.
