The Shure SM58 has been the world's standard vocal microphone for live performance since 1966. Sixty years later, it remains the microphone most commonly seen on professional stages, at karaoke systems, and in schools worldwide. Its dominance isn't nostalgia — the SM58 genuinely earns its reputation through reliable performance, near-indestructible build quality, and a frequency response tuned specifically for vocals.
Sound Character
The SM58's frequency response peaks around 5kHz with a presence boost that helps vocals cut through loud stage mixes. The built-in spherical wind and pop filter reduces plosives and wind noise without requiring an additional foam pop shield in most situations. Low-frequency rolloff below 100Hz reduces stand rumble and handling noise. This is a deliberate tuning — the SM58 is optimized for live vocals, not flat reproduction. For recording applications where a flat response is preferred, the SM7B or condenser microphones serve better.
The cardioid polar pattern provides approximately 15dB of rear rejection, usable on-stage without excessive feedback even at moderate monitor volumes. The proximity effect (bass boost when singing close to the capsule) can be used stylistically.
Build Quality
The SM58 is legendary for durability. Shure designed it for touring — the steel mesh ball grille protects the capsule from impact, the steel housing withstands drops, and the XLR connector is reinforced. Cases of SM58s surviving being run over by vehicles, dropped from stages, and retrieved from floods are common in audio folklore. This isn't hyperbole; the microphone genuinely outlasts most use cases.
The pneumatic shock mount system internally suspends the cartridge, isolating it from handling noise transmitted through the body. You won't hear hands gripping the microphone in recordings.
Live Performance Use
The SM58 is the industry standard for live vocal applications because sound engineers worldwide know how to mix it. When a singer holds a Shure SM58, the engineer at the FOH console has decades of collective experience with that specific microphone's characteristics. Visibility in a stage monitor feedback situation, gain before feedback characteristics, and behavior in various room acoustics are well-understood.
The SM58 works well for close-mic singing techniques. Its off-axis rejection is sufficient to use near other instruments (guitar amp cabinets, drum kits) without excessive bleed.
Recording Use
The SM58 can record vocals and speech adequately. The presence peak adds intelligibility to spoken word and singing. However, for recording-focused applications, the SM58's live-optimized character (presence boost, limited high-frequency extension above 15kHz) is less ideal than dedicated recording microphones. The SM7B provides a flatter response better suited to broadcast and recording. Condenser microphones capture more detail at the cost of increased sensitivity to room noise and handling.
SM58 vs SM58S (with Switch)
The SM58S includes an on/off switch on the body. Useful for performers who need to mute between songs without asking an engineer. The switch adds a potential point of failure — if you need maximum reliability and the switch serves no purpose, choose the standard SM58 without switch.
Verdict
The Shure SM58 at ¥18,700 is a straightforward recommendation for any vocalist performing live. It doesn't need justification beyond its track record. Buy an SM58 for: live performance, karaoke systems, public address applications, speech reinforcement, school/rehearsal use, or any situation where durability and proven performance matter more than studio-grade fidelity. For home recording-primary use, consider condenser microphones or the SM7B instead.
Frequently Asked Questions
Does the Shure SM58 need phantom power?
No. The SM58 is a dynamic microphone and does not require phantom power (48V). You can connect it directly to any mixer or audio interface XLR input. Phantom power won't damage the SM58 if accidentally applied, but it's not needed or used by the microphone.
What's the difference between SM58 and SM57?
The SM57 is designed for instrument miking — it has no built-in pop filter and a flatter frequency response that suits drums, guitar cabinets, and brass instruments. The SM58 has a larger ball grille with integrated pop filter and a presence boost optimized for vocals. Both share a similar cartridge lineage. The SM57 is the industry standard for instrument miking; the SM58 for live vocals. Neither is "better" — they're optimized for different applications.
Is the SM58 good for podcasting or streaming?
It works for speech-based recording and streaming, but it's not optimized for it. The SM58 requires an audio interface (XLR connection), and its live-oriented frequency response (presence peak around 5kHz) can sound somewhat forward for intimate speech applications. For podcasting or streaming, USB microphones like the Blue Yeti or Audio-Technica AT2020USB+ are more convenient (direct USB, no interface needed), and dedicated broadcast dynamic microphones like the Shure SM7B produce a warmer, more broadcast-appropriate sound. Use the SM58 for streaming if you already own one; don't buy it specifically for that purpose.
