Get clearer, more intelligible speech from your intercom system with this 12-pack of Solidcom C1 Headset Microphone Cushions from Hollyland . The foam cushion fits right over the microphone element and protects it from saliva and moisture to ensure the headset remains in good working order. The foam acts as a windscreen to reduce wind and breath noise and reduce consonant plosives noises such as those made by "P" and "B" sounds.
