Cardioid Mic vs Condenser: Two Rows, Not Two Choices

The question has a false shape. Cardioid and condenser aren't two kinds of microphone you choose between, because they answer two different rows on the same specification sheet. Every microphone has a polar pattern and every microphone has a transducer type, so the honest version of the comparison is what each of the two rows tells you and what it doesn't.

One row is about direction, the other is about electricity

Although both rows sit on one card, a polar pattern describes where a microphone listens while a transducer type describes how it turns pressure into voltage, with a dynamic capsule moving a coil through a magnet and a condenser capsule changing the gap between two charged plates. Neither answer constrains the other, so both rows appear on the same cards and both get filled in independently. Because of that, a shopper reading one row learns nothing about the other, which is the whole trouble with the question. Of the 82 microphone listings gathered here, 28 answer the element row with Dynamic and 39 answer it with some form of condenser. 14 carry no element row at all, and one answers 8x MEMS, which is a condenser by principle though not by the word used. Those four groups add to the whole 82, and only one of the four rows carries a consequence for what you have to buy.

Cardioid tells you nothing about the transducer

Here's the part that dissolves the question. 41 listings answer the pattern row with the single word cardioid, and among them the transducer split is almost even: 20 are dynamic, 17 are condensers of one kind or another, and 4 don't say. So the word you searched for lands you on either side of the real divide with roughly equal odds, and it doesn't tip either way. Cardioid is the default answer to its own row, and the full census of patterns across this collection shows how lopsided that default is, yet the point here is narrower. Knowing a microphone is cardioid leaves you a coin-flip away from knowing whether it needs phantom power, and phantom power is the thing that actually changes what you have to buy alongside it.

The transducer row does tell you one thing the pattern can't

Reverse the question and it stops being empty. 15 listings here name more than one polar pattern, and every one of the fifteen is a condenser. Thirteen of them switch. The other two are shotguns printing "Supercardioid / Lobar", which puts one pattern into two words rather than offering a choice. Not a single dynamic microphone in this collection offers a second pattern, and the fifteen spread wide rather than clustering: five USB microphones between $99.99 and $159, three shotguns and camera mounts, and seven studio condensers running from $453 to $14,999.99. But that isn't an accident of stock either. A switchable pattern is normally built by combining two back-to-back diaphragms, and the arrangement belongs to condenser construction rather than to a moving coil. What the switch costs is measured on three of the fifteen, and it runs to three or four decibels of self-noise between positions. So the element row predicts whether the pattern row can change at all, while the pattern row predicts nothing about the element.

Dynamics stay where they're put, and not one of the 28 fills in a self-noise row either. All 28 of them answer either cardioid or supercardioid and nothing else, so the eight supercardioids are the only variation the type allows here, and even that variation isn't switchable.

What the two rows cost

Yet money follows the element row rather than the pattern row, and by a wide margin. Half the 28 dynamic listings cost under $169, whereas half the 39 condensers cost over $410.00. Cardioid, though, costs whatever the microphone underneath it costs, because it spans both groups and can't distinguish them.

Even inside the condenser side the word hides a split. 10 of the 39 say electret condenser, and half of those cost under $139.99, which is below the dynamic midpoint rather than above it. An electret holds its charge permanently in the material instead of taking it from a supply, so it's cheaper to build and much cheaper to sell. The AT2020 in the photograph above is one of them, at $99.

The row goes missing on fourteen cards, and the name answers instead

14 listings have no element row, and reading them by name rather than by category explains most of it. Six describe things with no capsule at all, being a boom arm and five wireless receivers. Four are wireless systems where the card describes the receiver while the transmitter carries the capsule, so the missing row isn't a mistake on ten of the fourteen.

Two of the last four carry the answer in the product name. A Shure MV5 at $99 and a Shure SM35 at $115 both leave the element row empty while carrying the word Condenser in the product name itself, and in the SM35's case in the page address as well. So the field a buyer would sort on is blank, though the answer is printed across the top of the same page. Two cards out of 82 isn't a crisis, but it is the exact defect the question in the title is built on: somebody sorted by a column that wasn't filled in and reached for the product name instead.

Where the element row is filled in, what it changes is the diaphragm and the power, and those are the parts a specification sheet can actually describe. The MV5 also gives the clearest reading of the confusion this comparison rests on. Its pattern row says "Unidirectional (cardioid)", naming the category and then the pattern inside it, and no other card in the set gives both levels in one answer.

The box usually says both, and that's the answer

Once you look at how the microphones are actually named, the question answers itself. The AT2020 is sold as a Cardioid Condenser Microphone. The SM58 is sold as a Cardioid Dynamic Microphone. Both names carry the pattern and the type together, because a product needs both and neither excludes the other.

A handheld dynamic at $109 and a studio condenser at $99 sit ten dollars apart and share a pattern word, yet one wants phantom power and a quiet room while the other wants a hand and a loud stage. Nothing in the shared word predicts that. Everything in the unshared one does.

What the cards answer about cardioid and condenser

Is a cardioid mic better than a condenser?

The question doesn't resolve, because they describe different rows. A microphone can be cardioid and condenser at once, and 17 listings here are exactly that.

Are all condensers cardioid?

No. Of the 39 condensers here, 17 are cardioid and nothing else, 15 switch between patterns, and the rest name something else entirely.

Are all cardioid mics dynamic?

No, and it's close to even. Of the 41 cardioid-only listings, 20 are dynamic and 17 are condensers, with 4 not stating a type.

Which one needs phantom power?

The condenser, since it needs a charge across its plates. The pattern row won't tell you that, and the element row will.

Why does a listing say cardioid condenser?

Because it's answering both rows at once. The pattern is cardioid, the transducer is a condenser, and neither statement contradicts the other.

What to compare instead

Compare the element row against the element row, since dynamic against condenser is a real choice with a price attached and a power requirement behind it. Compare the pattern row against the pattern row, since cardioid against omnidirectional or supercardioid is a real choice about where the microphone listens.

Comparing one against the other produces the shape this page started with, which is a question that can't come out either way. Forty-one cardioid listings split almost evenly between the two transducer types, and that split is the answer. Whichever of the two rows you were really asking about, the other one was never going to settle it.
