Two microphones. Both made by Shure. Both dynamic. Both legends. One costs roughly four times more than the other. The question of which one you actually need is one of the most common — and most misunderstood — decisions in home recording.
Here is the clear, honest answer for 2026.
Quick Answer: SM7B or SM58?
Get the SM58 if you need a tough, affordable mic for live use, untreated rooms, or general recording. Get the SM7B if you record primarily in a treated space, do podcasts or voiceover, and can give it enough clean gain. Most people starting out are better served by the SM58.
What They Share
Both are dynamic cardioid microphones. Neither requires phantom power. Both reject sound from the rear and handle high sound pressure levels without distorting. Both are built to Shure’s legendary durability standards and will outlast most recording careers if treated reasonably well.
They share the same core philosophy: capture what is in front of them cleanly and reject everything else.
Where They Differ
The SM58 was designed in 1966 as a live vocal microphone. Its spherical mesh grille acts as a built-in pop filter and protects the capsule from real-world abuse. It has a gentle presence boost that helps vocals cut through a live mix. It is still the most widely used live vocal microphone in the world.
The SM7B was designed for broadcast and studio work. It has a flatter, more extended frequency response, excellent internal shock isolation, and useful bass-roll-off and presence-boost switches. It is the mic famously used on Michael Jackson’s Thriller vocals and by countless podcasters and voiceover artists.
The Gain Problem (This Matters)
The SM7B is a low-output microphone. Many budget interfaces (including the Focusrite Scarlett Solo) can power it, but quieter voices often need more clean gain than the interface can provide without adding noise. The common solution is an inline preamp such as a Cloudlifter CL-1, which adds roughly 25 dB of clean gain.
The SM58 needs no extra help. Plug it in and it works.
Typical prices (2026):
- Shure SM58: $99–$110 new / $60–$90 used
- Shure SM7B: $399–$440 new / $300–$380 used
- Cloudlifter CL-1 (if needed): \~$150
Shure SM58
Best for: Live vocals, untreated rooms, and anyone who needs a tough, affordable dynamic mic that just works
The industry-standard live vocal microphone. Durable, clear, and one of the smartest purchases under $110.
Shure SM7B
Best for: Podcasting, voiceover, streaming, and studio vocals in treated or quiet spaces
The modern broadcast and podcast standard. Smooth, detailed, and excellent at rejecting room noise — when given enough clean gain.
Which One Do You Actually Need?
- Choose the SM58 if you play live, record in an untreated room, need one mic that does everything, or want the lowest cost and complexity.
- Choose the SM7B if you mainly record spoken word or studio vocals in a decent space and are willing to handle the gain requirements (or add a Cloudlifter).
Do not buy the SM7B just because you saw it on a popular streamer’s desk. Buy it because your room and workflow actually benefit from what it does best.
Frequently Asked Questions
Is the SM7B worth the extra money over the SM58?
Yes — if you record podcasts, voiceover, or studio vocals in a controlled space and can provide enough clean gain. No if you mainly need a live mic or are on a tight budget.
Does the SM7B need a Cloudlifter?
Often yes with entry-level interfaces. Many people find the combination of SM7B + Cloudlifter transforms the results.
Can I use the SM58 for podcasting?
Absolutely. It works well, especially in less-than-perfect rooms. Many successful podcasts have been recorded on SM58s.
Does either mic need phantom power?
No. Both are dynamic microphones and do not require 48V phantom power.
Which is better for untreated rooms?
The SM58 is generally more forgiving in untreated or reflective spaces.
Final Recommendation
Most people should start with the Shure SM58. It is tougher, cheaper, simpler, and still sounds excellent. Move to the SM7B (and a Cloudlifter if needed) when your main work is spoken word or controlled studio vocals and you want the smoother, more detailed capture it provides.
Both are excellent microphones. The right choice depends on how and where you actually record.
