When it comes to live vocal microphones, two names come up constantly: the Shure SM58 and the Shure Beta 87. Both are industry standards, but they serve slightly different purposes depending on the singer, the stage, and the type of performance.
I’ve used both in real-world live situations, and this comparison breaks down which mic is right for you, without hype or specs-for-the-sake-of-specs.
If you’re deciding between the Shure SM58 and Beta 87A for live vocals, this comparison will help you choose the right mic for your stage, voice, and performance style — without guessing or overpaying.
Here’s a quick breakdown of how the SM58 and Beta 87A compare for live vocals.
Quick Overview
Shure SM58
- Dynamic microphone
- Extremely durable
- Forgiving on loud stages
- Found in nearly every venue
Shure Beta 87
- Condenser microphone
- More detailed and sensitive
- Requires phantom power
- Better for controlled stages
Both are excellent — but they are not interchangeable.
Sound Differences in a Live Setting
Shure SM58: Predictable and Forgiving
The SM58 is designed specifically for live vocals. It handles high sound pressure levels well, resists feedback, and smooths out harsh vocal peaks.
In practice, this means:
- You can move around the mic without drastic tone changes
- It works well with loud bands
- Sound engineers know exactly how to mix it
It may not sound “polished,” but it sounds reliable, which is often more important live.
Shure Beta 87: Clear and Detailed
The Beta 87 is a condenser mic, so it captures more detail and nuance in your voice. This can sound fantastic — when conditions are right.
You’ll notice:
- More clarity and air in the vocal
- Better articulation
- A more “studio-like” sound live
However, that extra sensitivity means it also picks up:
- Stage noise
- Poor mic technique
- Room reflections
Stage Volume and Feedback Control
This is where the two mics really separate.
SM58 on Loud Stages
If you’re playing with:
- Loud drums
- Guitar amps
- Wedges instead of in-ear monitors
The SM58 is usually the safer choice. Its dynamic design helps control feedback and bleed, even in challenging rooms.
Beta 87 on Controlled Stages
The Beta 87 shines when:
- Stage volume is low
- You’re using in-ear monitors
- The room is acoustically controlled
- The singer has good mic technique
In these environments, the clarity of the Beta 87 can be a big upgrade.
Durability and Reliability
SM58: Built Like a Tank
The SM58 is legendary for durability. Drops, moisture, travel, and years of gigs are exactly what it’s built for.
This makes it ideal for:
- Touring
- Rehearsal spaces
- Venues with shared gear
- Backup microphones
Many singers buy one SM58 and use it for decades.
Beta 87: Durable, but More Delicate
The Beta 87 is well-built, but it’s still a condenser mic. It’s not fragile, but it does require:
- Phantom power
- Slightly more care in transport
- A cleaner signal path
It’s better suited to singers who control their own gear setup.
Which Mic Should You Choose?
Choose the Shure SM58 if:
- You play loud stages
- You gig frequently
- You want a mic that always works
- You don’t control the venue or sound system
- You want maximum reliability

Final Thoughts
The SM58 and Beta 87 aren’t competitors so much as tools for different situations.
The SM58 remains the safest, most reliable choice for gigging musicians. The Beta 87 offers higher detail and clarity when the stage environment allows for it.
If you’re unsure, the SM58 is almost always the right place to start. Many singers later add a Beta 87 once their live setup becomes more controlled. Check out the Best Vocal Microphones for Live Performance article for additional insights.
One Last Tip
Using a reliable XLR cable is just as important as choosing the right mic for live performance, especially when consistency and durability matter on stage.
