The Broadcaster's Guide to Dynamic Microphones (2026)

If you have ever listened to a professional sports broadcaster or a morning radio DJ, you have heard the Electro-Voice RE20. It is the massive, gray, steel tube sitting on a boom arm in almost every professional broadcast studio in the world. Many beginner podcasters buy sensitive 'condenser' microphones, only to realize that the mic is picking up the air conditioner, the dog barking next door, and the echo of their own voice bouncing off the walls. Professional broadcasters don't have perfectly soundproofed rooms; they have perfect microphones. Dynamic microphones are intentionally insensitive. They only pick up audio that is two inches away from the capsule, rejecting all background noise. This guide explains why dynamic microphones are the only choice for spoken-word audio, and why the RE20 remains the undisputed king of the category.

The Radio Standard: Electro-Voice RE20

recommended88/100Good fit

Electro-Voice RE20 Broadcast Announcer Microphone

Electro-Voice

Electro-

The undisputed industry standard for radio broadcasting and voiceovers, featuring proprietary Variable-D technology that completely eliminates the proximity effect for a consistent, booming voice.

Why this pick: It has a built-in bass roll-off switch. If your voice is naturally very deep and muddy, you can flip the switch on the bottom of the mic to instantly tighten the low-end frequencies.

Pros

  • + Variable-D technology allows the host to move their head around without the bass response suddenly changing
  • + Built like an absolute tank; these microphones survive decades in abusive radio station environments
  • + The internal pop filter is highly effective at stopping plosives (P and B sounds)

Risks

  • - It is incredibly heavy and requires a heavy-duty, expensive broadcast boom arm to hold it up
  • - It requires a massive amount of clean preamp gain to reach broadcast levels
  • - It weighs nearly two pounds. If you attach it to a cheap $20 Amazon boom arm, the arm will immediately collapse onto your desk. You must buy a heavy-duty professional boom arm (like the Yellowtec m!ka or Rode PSA1+).
