The WS-HS1 is a high quality pop filter, designed to fit the HS1 and HS2 headsets. A pop filter should be fitted in the majority of applications to prevent any hard plosive sounds overloading the microphone capsule. The WS-HS1 is supplied as a pack of three and is available in both black (WS-HS1-B) and pink (WS-HS1-P).
