Portwest PW47 clip-on ear defenders SNR 27 dB

Portwest PW47 adds hearing protection to compatible safety helmets without a separate headband.

The cups can move away from the ears when protection is temporarily unnecessary. Soft cushions support comfort and sealing.

Attenuation is helmet- and fit-specific. Use only listed compatible helmets, calculate the requirement from a noise assessment and avoid both under- and overprotection.
