Shure SM4 Cardioid Condenser Microphone with Large Diaphragm | SM4-K
The Shure SM4 is a large-diaphragm cardioid condenser microphone designed to bring Shure’s studio heritage to home and project recording environments.
A large-diaphragm condenser captures vocals and instruments with detail and sensitivity, while the cardioid pickup pattern focuses on the source in front of the mic and rejects sound from the rear, helping tame untreated rooms. From lead vocals and voiceover to acoustic guitar and podcasting, the SM4 covers the core recording tasks that matter most to musicians and content creators.
