Dynamic microphones are rugged, need no power and pick up less room noise, which makes them ideal for podcasts, loud sources and untreated rooms. Condenser microphones are more sensitive and detailed, which suits vocals and acoustic instruments in a quiet, treated room, and they need 48V phantom power. If your room is noisy or echoey, start with a dynamic mic.
Dynamic and condenser microphones work differently, and the right choice depends as much on your room as on what you are recording.
How they work
- Dynamic: a diaphragm moves a coil in a magnetic field. Simple, tough and needs no power.
- Condenser: a thin diaphragm next to a charged plate. More sensitive and detailed, and needs power (usually 48V phantom power).
- Ribbon: a thin metal ribbon. Smooth and vintage-sounding, but fragile; a separate category.
Side by side
| Dynamic | Condenser | |
|---|---|---|
| Sensitivity | Lower | Higher |
| Detail | Good | Excellent |
| Room noise pickup | Less | More |
| Handles loud sources | Excellent | Good, check max SPL |
| Power | None | 48V phantom power |
| Durability | Very rugged | More delicate |
| Gain needed | More | Less |
What to use for what
| Source | Usual choice |
|---|---|
| Podcast and streaming | Dynamic |
| Vocals in a treated room | Condenser |
| Vocals in an untreated room | Dynamic |
| Guitar amp | Dynamic |
| Acoustic guitar | Condenser (small-diaphragm or large) |
| Drum overheads | Condenser |
| Snare and toms | Dynamic |
| Live vocals | Dynamic |
Why the room matters
Condensers hear everything: computer fans, traffic and the echo of bare walls. In a typical bedroom, a dynamic mic placed close to the mouth often sounds better than an expensive condenser. If you want a condenser, add soft furnishings, a rug and absorption behind you, and record close to the mic.
Gain
Some popular broadcast dynamic mics are very quiet and need a lot of clean gain. Check your interface’s gain range, or add an inline mic booster.
Polar patterns
- Cardioid picks up sound from the front and rejects the back; the default for most recording.
- Omnidirectional picks up all around; good for room sound.
- Figure-8 picks up front and back; used for duets and some stereo techniques.
Common questions
Is a condenser or dynamic mic better for vocals?
In a quiet, treated room, a condenser captures more detail. In an untreated or noisy room, a dynamic mic often sounds better because it picks up less of the room.
Do dynamic mics need phantom power?
No. Dynamic microphones don't need power. Condenser microphones need 48V phantom power from your interface or mixer.
What is the best mic type for podcasting at home?
A dynamic mic in most cases. It rejects room echo and background noise, so voices sound closer and cleaner.
