Designed for performing artists, the Shure SM39 microphone headset features a comfortable headband that stays firmly in place for the whole show, while the gooseneck-mounted capsule can be precisely positioned to ensure the best signal-to-noise ratio and the best sound. The cardioid polar pattern is extremely focussed, helping to almost completely eliminate crosstalk, while moisture-resistant coating fully protects the microphone, even during more intense gigs.
