3M Peltor Optime II H520B mušľové chrániče sluchu s temenným mostom 31 dB zelené

The 3M Peltor Optime II H520B stands out with its neckband design, offering a secure fit that works well with helmets and other head protection. Unlike standard headband models, this style keeps the band behind the neck, reducing interference and improving comfort during long shifts in noisy environments.

Highlights

• High attenuation with SNR 31 dB for very noisy workplaces
• Neckband design compatible with helmets and face shields
• Soft, wide sealing rings filled with foam and liquid for a comfortable seal
• Low contact pressure and generous space inside ear cups reduce heat and sweat build-up
• Durable ABS plastic ear cups in green

In daily use

These passive ear defenders are built for heavy industry, construction, airports, and agriculture. The neckband keeps the cups firmly in place without pressing on the top of the head, making them ideal for workers who wear hard hats or need to tilt their head frequently. The sealing rings conform to the shape of the head, providing reliable protection even during movement.
