What to check before buying
- Compare the exact model’s current attenuation documentation with the assessed noise exposure and communication requirements.
- Confirm headband, neckband or helmet-mounted format; check approved helmet adapters where a mounted version is needed.
- Check that glasses, headwear and other PPE do not compromise the manufacturer’s required fit and seal.
- Read the supplied quantity and availability of the correct replacement cushions or hygiene kit for that model.
