The HZH 280 are disposable hygiene pads to protect the earpads of the HDA 200 and HDA 280 audiometry headphones and the HME 100, HMEC 300 and HMEC 400 series aviation headsets. These half-transparent white single use pads can simply be pulled over the earpads. For applications where the same headphones have many different users, using the HZH 280 will help to ensure the highest possible standards of hygiene.
