Shure RK311

Essential Information About the Shure RK311 Windshield

• Effective Air Noise Reduction: limits plosives and turbulence for cleaner recordings, both in the studio and on location.


• Dedicated Compatibility: designed to fit precisely on the Shure SM81 microphone.


• Lightweight and Discreet Foam: preserves natural sound while providing basic mechanical protection to the capsule.


• Compact Size: easy to keep in place without interfering with microphone placement in front of a source.

A Shure Accessory Designed to Accompany the SM81 Daily

The SM81 is a condenser microphone known for its precision and neutrality, highly appreciated on acoustic instruments, drum overheads, or ambient recordings. The Shure RK311 aligns with this "ready to record" reliability: a simple, robust, and tailored windshield designed to secure recordings when moving air becomes a factor (breath, movement, ventilation, stage, outdoors).

Who It's For and Intended Uses

The RK311 is aimed at sound engineers, home studio users, stage technicians, and musicians who use a Shure SM81 and want to reduce unwanted noise caused by wind or explosive consonants. It is particularly useful for close-miking (wind instruments, spoken/sung vocals as support, percussion), but also whenever airflow can disturb the capsule (air conditioning, movements around the mic stand, outdoor recording). Besides improving clarity, it helps limit accidental distortion caused by "air blasts."

Protection, Filtration, and Integration: The Essentials Without Complicating Recording

Windshield Foam: A Simple Step for Cleaner Recordings

Thanks to its foam design, the RK311 acts as a mechanical filter: it reduces turbulence before it reaches the capsule. The result: less breath noise and plosives, and dynamics that are easier to manage at the preamp. It's a quick accessory to install, ideal when you want to secure a take without changing the setup.

Compatibility and Secure Fit

With its adapted internal diameter, the windshield fits stably on the microphone, preventing slippage during a session. Its size maintains good maneuverability for placement, especially when the SM81 is positioned close to a source (strings, cymbals, acoustic amp, ambient recording).

Subtle Finish for Studio and Stage Integration

In black, the RK311 integrates easily into a microphone collection and remains discreet on camera. It's a relevant choice for environments alternating between studio, rehearsals, and live performances while maintaining a clean appearance.
