The Shure SM58 is a professional audio icon, known for its durability and frequency response ideal for live vocals since 1966.

About this subject

The Shure SM58 is a dynamic cardioid microphone launched in 1966 by Shure Incorporated. Originally designed for live vocal applications, it quickly became the industry standard for its reliability and consistent sound. Its frequency response of 50 Hz to 15 kHz is optimized to enhance vocal clarity, while the cardioid polar pattern rejects sounds from the rear, reducing feedback and ambient noise.

The SM58's design is notably rugged. It features a steel mesh grille that protects the microphone element, a durable switch, and a robust body that withstands drops and impacts. Stress tests include drops from 1.5 meters and exposure to extreme temperatures. This microphone also has a pneumatic shock mount capsule that minimizes handling noise, ideal for performers who hold the microphone during shows.

Culturally, the SM58 is one of the best-selling microphones worldwide, with millions of units sold. It has been used by legendary artists such as Freddie Mercury, Bruce Springsteen, and Kurt Cobain, as well as political figures like Barack Obama and Nelson Mandela. Its presence on stages of all sizes, from small clubs to stadiums, is almost guaranteed. The microphone is also common in recording studios for vocals and instruments, though it is best known for live sound.

Technical trivia: the SM58 shares the same cartridge element as the Shure SM57, but with a different grille for wind and saliva protection. Both are dynamic microphones that do not require phantom power. The SM58 also has a wireless version, the SM58 Wireless, which maintains the same sound quality. Its popularity has endured for over five decades, often recommended as the first professional microphone by educators and audio engineers.
