Sm58 microphone classic

Learn all about the Shure SM58, the world's most iconic vocal microphone, used by artists like Freddie Mercury and Bono Vox.

About this subject

The Shure SM58 is a dynamic cardioid microphone launched in 1966 by Shure Incorporated, becoming the gold standard for live vocals and recordings. Its popularity stems from a combination of durability, voice-optimized frequency response, and off-axis noise rejection. The rugged steel grille and internal shock mount protect the cartridge from impacts and heavy handling, allowing the microphone to survive drops and tour use.

The SM58 has a frequency response of 50 Hz to 15 kHz, with a slight mid-high boost for vocal presence without sibilance enhancement. Its dynamic capsule does not require phantom power, operating solely on balanced audio signals via a 3-pin XLR male connector. The cardioid rejection pattern reduces feedback and captures sound mainly from the front.

Culturally, the SM58 is synonymous with live performance. From rock concerts to political speeches, its silhouette is recognized worldwide. Artists such as Freddie Mercury, Bono Vox, and Bruce Springsteen have used it. It is also common in karaoke bars, churches, and PA systems. Despite newer, more expensive models, the SM58 maintains the trust of sound engineers for its reliability.

Controversies: many believe the SM58 has a "colored" sound; in fact, it is neutral and designed to avoid sibilance and handling noise. Another myth is that the SM58 and SM57 are identical, but the SM58 has vocal-optimized response while the SM57 is for instruments. The model has remained in production for over 50 years with few changes, a testament to its timeless design.
