Kailh BOX Red vs Kailh Red

The Kailh Red and the Kailh BOX Red sit in different price brackets, which across the 70-odd switches a board needs is a bigger difference than most of the spec sheet. Our library of every switch we simulate links the two to each other for that reason. Play the A/B bursts below to hear them back to back, match the volumes, then read the spec table and the verdict.

Spec by spec

Spec Kailh BOX Red Kailh Red
Type Linear Linear
Brand rates force at actuation actuation
Actuation force 45 g 50 g
Bottom-out force 60 g (our estimate) not published
Pre-travel 1.8 mm 2 mm
Total travel 3.6 mm 4 mm
Silent (dampened) No No
Factory lubed No No
MX-compatible stem Yes Yes
Price tier Mid-range Budget
Street price varies varies

Kailh advertises an actuation force for both of these, so the two headline figures in this table are measured at the same point and can be read against each other. Kailh publishes no bottom-out figure for the Kailh BOX Red, so the figure marked "our estimate" is our own derivation from the forces that are published rather than a rating. How we derive a bottom-out figure .

Verdict

The Kailh BOX Red and the Kailh Red are both linears, so nothing separates them at the fingertip until you look at springs and acoustics. Price splits them too: the Kailh Red is the budget friendly option while the Kailh BOX Red sits in the mid priced bracket, which adds up across a 70 switch board. The Kailh Red is the firmer of the two at actuation, 50 g to 45 g, though 5 g is not much to choose between. The Kailh BOX Red comes out ahead of the Kailh Red for gaming and for typing, and it is the safer of the two in a shared room, so this comparison has one answer instead of a set of them.

Overall pick
Kailh BOX Red

Force curves

Kailh BOX Red

Force curve (illustrative)
25g 50g 3.6mm travel 45g @ 1.8mm 60g bottom-out (our estimate)

Kailh publishes no bottom-out force for this switch, so the 60 g at the end of the stroke is our estimate and the run into it is dashed. Everything up to actuation comes from the published numbers. How we derive it.

Kailh Red

Force curve (illustrative, from published specs)
26g 52g 4mm travel 50g @ 2mm bottom-out not published

Kailh publishes no bottom-out force for this switch, so the dashed end of the curve is an estimate, not a spec. Everything up to actuation comes from the published numbers.

Kailh BOX Red or Kailh Red: the long answer

Money separates these two more cleanly than any spec does. The Kailh BOX Red is mid priced, while the Kailh Red is budget friendly. Neither ships lubed, so budget an evening with a brush if you want either at its best.

That leaves the stroke itself. At actuation the Kailh Red is the firmer press, 50 g against 45 g, a difference you notice after a paragraph rather than on the first keystroke. The stroke itself is shared: nothing sits between the top of either key and the bottom. Travel differs at both ends, with the Kailh BOX Red registering first at 1.8 mm and the Kailh Red running deepest at 4.0 mm. None of these gaps is large. Stack them up and they still point somewhere, but gently.

The ears usually get the last word here. Through the A/B player above, the Kailh BOX Red comes through as clean, slightly hollow clack; tight and consistent, while the Kailh Red reads as familiar MX-clone clack with a touch more scratch. One caveat we repeat wherever a player appears: no studio recording sits behind either of these. They are built from what each maker publishes and what the community reports.

So who should buy which? The same switch wins every way we score it: the Kailh BOX Red is our pick for gaming, for typing and for a shared desk. On speed, the two are close enough here that either works, and our scoring gives it the nod by a hair. On typing feel, it holds the same feel from the first hour of writing to the last. On noise, it is the one of these two you would not apologize for. That leaves the Kailh Red to anyone who preferred its voice in the player above, which is a good enough reason on its own. The player above is the cheapest part of this decision, so use it before your wallet is involved.

Frequently asked questions

For gaming, should I buy the Kailh BOX Red or the Kailh Red?

We pick the Kailh BOX Red for gaming. This is close to a coin toss. The scoring hands it over by a margin you would not feel in a match.

Which of the Kailh BOX Red and the Kailh Red is quieter in a shared room?

Nothing in either one is built to reduce noise, so on raw volume this is a tie decided by your keyboard rather than your switch. What you will actually hear is a difference of pitch and texture, which the player above shows better than a sentence can.

Is the Kailh BOX Red heavier than the Kailh Red?

The Kailh Red. Both brands publish at actuation, which makes 50 g against 45 g an honest 5 g rather than two numbers from different rulers.

Which is cheaper to fill a board with, the Kailh BOX Red or the Kailh Red?

The Kailh Red sits in the budget friendly bracket and the Kailh BOX Red in the mid priced one. We do not hold a reliable per-switch price for both, so the bracket is the honest answer rather than a total.
