The Shure SM39 is a high-performance directional headset designed for professional touring engineers. Its cardioid polar pattern provides excellent off-axis rejection and high gain before feedback, allowing you to move freely on stage without worrying about bleed from other instruments. The ergonomic and adjustable design features a stable headset frame that stays securely in place even during intense performances. The sliding boom lets you precisely position the microphone element for optimal pickup, ensuring your voice cuts through the mix with clarity. Constructed with an all-black frame and durable TA4F and LEMO connectors, the SM39 is built for the rigors of professional use. Its high RF resistance also ensures compatibility with digital wireless systems. Included snap-fit windscreens allow you to use the microphone confidently in both indoor and outdoor environments, shielding against plosives and wind noise for pristine vocal capture.
