The "upgrade" to the Shure SM57. The Shure Beta 57A is a dynamic microphone that utilizes a super cardioid pickup pattern for better side rejection, it’s 4dB louder than a 57, has a hardened grille with built in pop filter, wider frequency response (50Hz-16kHz) and far less sensitive to handling noise (internal shock mount). Listen to the Beta 57A in Shure’s Mic Listening Lab.
