The Portwest PW74 Dual SNR Ear Defenders are designed for workers exposed to a range of noise levels. One pair offers two attenuation settings, medium at SNR 25dB and high at SNR 35dB, so you can change the protection level manually as noise levels differ.
A dial on the ear cup shows the selected level. This lets you and others confirm at a glance that the correct attenuation is set.
Key features

Switching protection levels
The protection level is changed manually using the dial on the ear cup. The dial clearly displays whether the SNR 25dB or SNR 35dB setting is selected, so the correct attenuation can be identified when you move between different noise levels.
