The Azden SWS-250 is a professional "furry" or "dead cat" windshield specifically engineered for use with the Azden SGM-250 and SGM-250P shotgun microphones. Its primary function is to provide exceptional protection against wind noise during outdoor audio recording, a critical concern for field production, documentary filmmaking, news gathering, and location sound work. The windshield employs a two-layer design: a dense inner foam layer that provides initial wind resistance and physical cushioning, and a long-pile synthetic fur exterior that effectively dissipates the energy of moving air before it can strike the microphone's grille and capsule. This combination dramatically reduces low-frequency rumble, buffeting, and popping sounds caused by wind, enabling clean, usable audio capture even in moderate to breezy conditions.

The SWS-250 is custom-fitted to the specific dimensions and shape of the SGM-250 series microphones, ensuring a secure, snug fit that stays in place during movement and does not contact the microphone's sensitive grille. This precise fit is crucial, as any internal movement or rubbing can introduce its own noise. The windshield typically attaches via an elastic band or hook-and-loop closure, allowing for quick installation and removal. By mitigating one of the most significant environmental challenges in location audio, this accessory greatly expands the operational versatility of the SGM-250 microphone, allowing sound recordists and videographers to achieve professional-grade audio results in a wide variety of outdoor environments without the need for bulky blimps or larger wind protection systems.
