4O3A MC-1 Windscreen Foam Replacement
4O3A MC-1 Windscreen Foam Replacements are identical to those supplied with the MC-1 Boom Mic. The microphone foam is not only a sibilance and pop filter that ensures a better reproduction of your voice, but it is a point of hygiene, too. We recommend swapping the foam if anyone else uses your headset. Order extras to have on hand for guest operators or to make the boom mic just like new after any period of use. This black foam "microphone sponge" is the correct size to fit the 4O3A MC-1 Boom Mic.

Keep your NC1 Bluetooth Headset working like new and don't let worn out ear cushions diminish your comfort and listening experience.
