Thocky vs Clacky: What Makes a Mechanical Keyboard Sound Good

Spend five minutes in keyboard communities and you'll see two words over and over: thock and clack. They're not technical terms, and people argue about where one ends and the other begins. But they describe something real, and once you know what shapes a keyboard's sound, the debate makes a lot more sense.

What "thocky" and "clacky" mean

Thocky usually describes a deep, rounded, muted sound — more "bass" than "treble." Think of a wooden block tapped with a soft mallet.

Clacky describes a brighter, higher-pitched, sharper sound — the crisp, plasticky "clack" of a key snapping down onto something hard.

Neither is better. Some people find thock calming; others find clack energetic and satisfying. Most keyboards fall somewhere in between, and the same switch can sound thocky in one build and clacky in another. That's the key idea: the sound comes from the whole keyboard, not just the switch.

1. Switches: linear, tactile and clicky

The switch under each key sets the basic character of the sound. Mechanical switches are roughly grouped into three families.

Linear

Linear switches go straight down with no bump. The sound mostly comes from the stem hitting the bottom of the housing (bottom-out) and returning to the top (top-out). Cherry MX Red is the classic example. Because there's no extra mechanism, linears are often the starting point for "thocky" builds.

Tactile

Tactile switches have a bump you can feel partway down. Cherry MX Brown is the best-known one and has a fairly light bump; Cherry MX Clear is noticeably heavier with a stronger bump. The bump itself is usually quiet — the sound still comes mostly from bottoming out — but the extra force can change how hard people press.

Clicky

Clicky switches add a dedicated mechanism that makes a sharp click as you press. Cherry MX Blue is the famous one. Clicky switches are the loudest and highest-pitched of the three, and the click is there no matter how gently you type. Great for some, not so great in a shared office.

There are also low-profile switches, with shorter travel and a slimmer housing, used in thinner keyboards. They tend to sound lighter and quieter than full-height switches of the same type.

2. Keycaps: material, thickness and profile

The keycap is the part your finger touches, and it acts a bit like the body of a drum.

• ABS plastic is common and smooth. It's often associated with a slightly higher, clackier sound, and it can get shiny with use.
• PBT plastic has a textured feel and is generally harder and more resistant to shine. People often describe PBT sets as sounding a bit deeper or duller.
• Thickness matters as much as material. Thicker walls generally sound lower and more solid; thin caps sound hollower and brighter.
• Profile (the shape and height of each cap) changes the size of the air space inside it. Taller profiles are often described as sounding deeper.

These are tendencies, not rules. A thick ABS set can sound deeper than a thin PBT set.

3. Plate, case and mounting

Under the keycaps, switches usually sit in a plate, which sits in a case. Both resonate.

• Plate material: stiffer metals like aluminum and brass tend to give a brighter, sharper sound. Softer materials such as polycarbonate or POM are often chosen for a muted, deeper sound.
• Case: a hollow case can ring or echo. Many builders add foam to damp it, which usually pushes the sound toward thock.
• Mounting: how the plate attaches to the case (for example "gasket mount," which uses soft gaskets) affects how much vibration reaches the case and how the board feels under the fingers.

4. Tuning: lube, springs and stabilizers

Lubricating switches reduces scratchiness and spring "ping," which typically makes the sound smoother and a little deeper. Large keys like the spacebar have stabilizers that can rattle; tuning them is often the single biggest improvement on a cheaper board.

5. The room — and the microphone

A keyboard on a wooden desk sounds different from the same keyboard on a desk mat. And when you hear a keyboard in a video, you're also hearing the microphone, its placement and any processing. That's why the same switch can sound wildly different from one video to the next.

Why "good" is personal

It's tempting to look for the one best-sounding keyboard, but preference depends a lot on context. A deep, quiet thock is pleasant at night or on calls. A bright clack can feel more lively when you're typing fast. Many people also simply like what they started with. If you're unsure, listen to the same switch in a few different builds before deciding — and pay attention to how it sounds at your typing speed, not just single, slow presses.

Quick cheat sheet

• Toward thock: thicker or PBT keycaps, softer plate (polycarbonate, POM), foam in the case, lubed linear or tactile switches, a desk mat.
• Toward clack: thinner or ABS keycaps, metal plate, hollow case, unlubed switches, a hard desk.
• Loudest and brightest: clicky switches, regardless of the rest.

Hear the difference without buying five keyboards

In Keycap Lab, every material plays a real mechanical-keyboard recording, so you can press different sounds side by side. A few of the recorded switches are known:

• Ice — Cherry MX Blue (clicky): bright and sharp.
• Candy — Cherry MX Clear: a heavier tactile switch.
• Slate — Cherry MX Brown: the classic light tactile.
• Felt — Gateron Brown low-profile, recorded on a Keychron K7 Pro.
• Glass — Hako Violet.

Put Ice and Slate next to each other on your pad and alternate: the difference between a clicky and a tactile switch is obvious in a few presses. It's free, has no ads and works offline. For more on getting keyboard sounds on your phone, see keyboard ASMR apps for iPhone.
