The 3M Peltor Optime III headband ear defenders are a super-muff for extremely noisy environments. They give you high attenuation across both high and low frequencies.
Speech and warning signals stay easy to understand while you wear them. Broad, foam-filled sealing rings give a good seal with low contact pressure. This makes them easier to wear for longer periods.
Key features
- Double casing construction minimises resonance in the cups, giving maximum high-frequency attenuation
- Speech and signals remain easy to understand, so you can stay aware of colleagues and alarms
- Acoustic connection between the inner volume and the space between the casings provides maximum low-frequency attenuation
- Broad sealing rings filled with soft plastic foam give a close fit around the ears
- Low contact pressure from the sealing rings helps when you wear them for long periods
- Headband design for over-the-head wear
