Quiet mechanical keyboards for offices and shared rooms

Updated

A mechanical keyboard doesn't have to be loud. The noise that annoys colleagues comes from a few specific places, and most of them can be dealt with by picking the right switch or adding a few pounds' worth of parts. A well-chosen board can end up quieter than the laptop keyboard it replaces.

This guide is for anyone typing in an open-plan office, a shared flat or next to a sleeping partner. The “muted” tag we use on products is our own editorial judgement, not a decibel measurement, so treat it as a starting point rather than a guarantee.

Where the noise comes from

Four sounds make up most of the racket.

Bottoming out: the stem hitting the bottom of the switch, and the keycap hitting the top of the switch, at the end of every press. On most boards this is the loudest part.

Topping out: the stem snapping back up against the top housing when you let go. It's sharper and easy to overlook until you've fixed bottom-out.

Stabiliser rattle: the wire under the space bar, Enter and Shift keys. It's often the single most noticeable noise to someone sitting nearby, because the space bar gets hit so often.

Clicks: the deliberate click in clicky switches. Nothing else on this list is as loud.

A silent switch deals with the first two. Lubed stabilisers deal with the third. Not buying clicky switches deals with the fourth.

Silent switches

Silent switches add dampers, usually a soft insert on the stem, that cushion both ends of the stroke. The trade-off is feel: they bottom out softly rather than crisply, and travel is often a fraction shorter. Most people stop noticing within a day or two.

The quietest options are silent linears. Cherry's Cherry MX2A Northern Light has a noise-damped stem, factory lube and 3.7 mm of travel instead of the usual 4 mm[1]. The Cherry MX2A Silent Red is the silenced version of Cherry's standard Red with the same 45 cN weight[2], and Keychron's Keychron Silent K Pro Red is a damped linear sold as a drop-in for its hot-swap boards[3].

If you want a bump, Gazzew Boba U4 is the usual silent tactile: the same round bump as the popular U4T, with a dampened stem[4]. Silent tactiles are rarer than silent linears, so there's less to choose from.

Buy a small pack before a full set. The dampers change the feel more than the spec sheet suggests: some silent switches end the stroke with a soft thud, others feel slightly spongy at the bottom. Fit a few under the keys you use most, live with them for a day, and only then order the rest.

A full board needs anywhere from about 65 to over 100 switches, so price the whole set before you choose. On a hot-swap board you can fit them yourself in under an hour; our hot-swap guide explains how to tell whether yours is one.

Boards that are quiet out of the box

If you'd rather not swap anything, buy a board that ships with silent switches as an option. Check the exact listing, since most of these are sold with louder switches too.

  • Cherry KC 200 MX: £90.40; wired full-size, UK layout, sold with MX2A Silent Red; plain and built for an office
  • NuPhy Halo75 V2: 75%, US layout only, offered with Cherry MX Silent Red switches and a thick dampening stack
  • Leopold FC660M PD: £85.99; compact wired board, US layout, available with Cherry MX Silent Red
  • Epomaker TH80 V2 Pro: 75%, wireless, US layout, offered with Epomaker's Sea Salt Silent V2 switches

Cherry's KC 200 MX is the most office-friendly of these: a plain full-size layout in UK ISO, no lighting beyond the lock indicators, and a choice of MX2A Silent Red or MX2A Brown[5]. It's wired and soldered, so what you buy is what you keep.

Two boards sit slightly apart. The HHKB (PFU) HHKB Professional HYBRID Type-S uses silenced Topre switches, a rubber-dome-and-spring design with a cushioned, very quiet press[6]. It's expensive, and only sold in its own compact US and Japanese layouts. The Logitech MX Mechanical is sold with a Tactile Quiet switch option among its three[7]. Logitech doesn't say how it's quietened, so if you can, compare it by ear with the damped switches above.

Making a board you own quieter

Lube the stabilisers. This gets rid of rattle on the long keys and costs little more than a pot of grease. It means taking the board apart, so read our lubing guide first.

Add foam. Foam between the plate and PCB, or in the bottom of the case, absorbs the hollow ring that some cases make[9]. Many current boards already have it; older and cheaper ones often don't. KBDfans Module Foam comes in small pieces you stick to the plate, so it fits almost any layout.

Switch pads. These thin adhesive pads sit on the PCB under each switch and soften the bottom-out[8]. They work on hot-swap boards without soldering.

A desk mat. A thick mat under the board stops the desk itself acting as a sounding board. It won't fix the switches, but it takes the edge off.

Typing lighter. Free, and it works. Most switches actuate around halfway down, so you don't need to hammer each key to the bottom.

What to avoid

Clicky switches, obviously. Kailh Box Jade and Cherry MX2A Blue are fun at home and a menace in an office. Some boards come with a blue or clicky switch as the default, so check the listing before ordering.

Hollow plastic cases with no foam, and thin ABS keycaps, tend to sound higher and louder. They're less of a problem than the switch and stabilisers, but worth bearing in mind if two boards are otherwise equal.

If you're still choosing, our quiz lets you ask for a quiet board and narrows the catalogue down accordingly.
