PROTOS Ear Protector Insulating Inserts SNR-27

To ensure maximum hearing protection and hygienic reasons, you should periodically replace the sound insulation inserts for the Protos ear muffs. The insulation inserts sit inside the cup, behind the support pads, and you can easily install these genuine Protos replacement parts without the need for tools. As a best practice, it is a good idea to replace the Protos outer support pad simultaneously. Certified EN352-3 HPD exceeds Class 5 with an SNR rating of 27.
