NEO's 97-567 helmet ear muffs allow you to work with an industrial helmet and ear muffs at the same time. They are particularly useful in factories where both head and hearing protection are required. They are characterised by an SNR of 29 dB. They have a soft finish for increased wearing comfort. The adjustable height of the earmuffs and the ability to tilt and swivel the arms allow the wearer to work with the earmuffs attached, without having to detach them from the helmet in the event of a change in audibility. The product is compatible with all NEO TOOLS brand helmets. It is CE certified.
