Dynamic vs Condenser Mics: Which is Best for Podcasting?

One is powered by your voice. The other by electricity. Want to know why understanding which is which is crucial to choosing your right mic?

Introduction

There are two main types of microphones used for podcasting – dynamic and condenser. Let’s compare the pros and cons of each to help you decide which is best for your podcast.

What is a Dynamic Microphone?

A dynamic microphone converts sound waves into an electrical audio signal with just the power of your voice – no electricity.

Your voice slams into a tiny coil of wire sitting in a magnetic field, and presto! Out comes sound. So, to get a rich sound, you need to be loud or close to the mic, or both!

Although there are some dynamic mics that plug straight into computers it is more common that dynamic mics need some sort of device sitting between the computer and mic to boost the audio signal. It’s an extra expense you need to think about.

Dynamic mics are known for being sturdy, durable, and able to handle high volumes without distortion. They don’t require external power and are relatively affordable. The Shure SM7B and Audio-Technica ATR2100x are popular dynamic microphone choices for podcasting.

Pros of Dynamic Mics:

• Durable build quality – can withstand accidental drops or knocks. Good for taking on location.
• Don’t require phantom power – can plug directly into interface or mixer. More convenient for portable recording.
• Handle high input volumes – won’t distort when close up on loud sources like drums or guitar amps. Good for recording loud vocals.
• Noise rejection – Good at isolating voice from background noise (think air conditioners or traffic sounds). The directional polar pattern helps reject off-axis sounds (I’ll explain what this gobbledygook means in another post very soon!).
• Warm, rich tone – excellent for vocal recordings like podcasts.

Cons of Dynamic Mics:

• Less sensitive – require speaking/singing closer to capsule.
• Heavier – bulkier design can cause fatigue if handheld for long periods.
• Fixed polar pattern – most have cardioid pattern so less flexible.
• You will most likely need to buy an additional device to boost the audio signal or your voice will be too quiet on your recording.

What is a Condenser Microphone?

A condenser mic uses electricity to convert your voice to an audio signal. So, you have to supply it with power. This makes them more sensitive and great in a sound-treated recording studio. It’s not so great in your average bedroom, where it might pick up the sound of your neighbours arguing.

So why would you buy one if you don’t have a studio? Well, it’s simpler to set up and can provide more options than dynamic mics. This is because many condenser mics can plug straight into a computer via a USB cable. And the power supplied by the cable will make sure your voice is nice and loud. So, there is no need to buy an additional device to boost the signal.

Plus, some condenser mics come with apps that can make your podcast production a lot easier.

Examples of condenser mics used for podcasts include the Rode NT1-A and Blue Yeti.

Pros of Condenser Mics:

• Very sensitive – can capture subtle, quiet sounds. Ideal for whispered or quiet vocals.
• Extended frequency response – condensers have a very neutral, transparent sound perfect for podcasts.
• Multiple polar pattern options – many condensers have switchable polar patterns for more flexibility.
• Lighter weight – easier to hold for long periods without fatiguing.

Cons of Condenser Mics:

• Require phantom power – not as convenient for field recording without external power.
• Fragile – condenser capsules are delicate and can be damaged by shock or drops. Need to be handled with care.
• Pick up unwanted noises – very sensitive so will capture computer fans, AC units, traffic noise etc if not isolated properly.
• Can’t handle high SPL – distorted by very loud sound sources. Not suitable for loud instruments or vocals.

Which is Better for Podcasting?

For most podcasters, a dynamic microphone will provide the easiest, most convenient option. The robust build means it can be taken anywhere without fear of damage. The rejection of off-axis sounds helps isolate the voice from room acoustics or ambient noise. Warm, natural vocal reproduction is ideal for podcasts.

However, for studios or very controlled recording environments, a condenser can capture more nuance and detail. If background noise isn’t an issue, and you want pristine, transparent vocal pickup, a condenser like the Rode NT1-A is a great choice. Just ensure you have phantom power available.

It’s worth noting that some podcasters use both! For example, a dynamic mic for Skype interviews which might have variable internet connectivity. And a studio condenser for high-quality solo recordings. This gives the flexibility of using the right mic for each scenario.

Conclusion

So which to buy? Every situation is different but let’s use one factor as our compass – background noise.

Think about where you are recording. If you can’t control the background noise, then go for a dynamic mic.

If you can reduce or compensate the background noise to a level that won’t distract from your recording, then a condenser mic is a good and often cheaper option. Especially if it comes with apps to help your production.

To get an idea of the background noise in a room use your phone.

Use the in built voice recorder or voice memo function. Leave it recording the “silence” in your proposed studio. Then listen back to it using your earbuds or headphones on a high volume. You will be surprised what a simple phone mic picked up. And everything you hear will be picked up and amplified by the mic you buy. In triplicate if it’s a condenser mic.
