The Abko ACH108 keeps typing quiet without disappearing visually. A scrolling dot-matrix display, space-inspired colors, and silent switches give it personality without a loud soundtrack. It’s a particularly useful combination for an office or study desk where a numpad is part of the daily routine.
Unboxing: Essentials Only
The package includes the keyboard body, a manual, a combo keycap and switch puller, a USB-C cable, and 4 spare switches. It supports hot-swapping, allowing you to pull both keycaps and switches with a single puller. It is a strictly necessary setup, though the dust cover—which has become quite common these days—is missing.
Space-Inspired Design and Dot Matrix Display
The keyboard comes in three colors: Lunar Silver, Starlight, and Dream Pink, all inspired by space. The Starlight model I am reviewing pairs a dark base with black and gold accents, and the combination really sets the mood. Colors can look different in photos depending on the lighting, but in person the tone is calm and looks great.
The element that catches the eye first is the dot matrix display, which allows you to show custom text. Though it is a single-row mini screen, the characters scroll smoothly, which makes customizing it genuinely fun.
An RGB sidebar angled slightly forward on the side adds a nice accent point.
Bsun Lavender Switches: Quiet Tactile
The switches come in two silent variants: Lavender (tactile) and Sakura (light and smooth linear). Both are manufactured by Bsun, and my unit has the Lavender switches, rated at 45gf. Both options target noise-sensitive environments like offices and study rooms. If you want tactile feedback with reduced noise, the Lavender is the right choice. If you prefer a smooth, bump-free feel, the Sakura is the way to go. Since it supports hot-swapping, you can simply swap out the switches later if your preferences change.
Lavender Switch Typing Sound: Quiet Without Feeling Muffled
Even with a gasket-mounted foam structure, it lacks the muffled feeling typical of silent switches, leaving only office-appropriate quietness. Even people who do not usually enjoy silent switches will likely adapt without much trouble.
Recordings depend heavily on the room and microphone setup. I didn’t add microphone gain to my Lavender typing video, and looking back, I may also have been typing rather gently.
Keycaps: Thick PBT Dye-Sublimation
The keycaps are made of 1.7 to 1.8mm thick PBT with dye-sublimated legends rather than double-shot injection. They are quite resistant to shine, making them a great match for office work. I personally prefer PBT double-shot keycaps, but this design featuring falling stars is pretty enough to make it worth using anyway.
Web Driver, Tri-Mode Wireless, and Battery
It supports USB Type-C wired, 2.4GHz wireless, and Bluetooth tri-mode connectivity, working seamlessly across Windows and macOS. You can switch between PCs, laptops, tablets, and smartphones.
The web-based driver lets you change key mappings, macros, and display text without installing software. Lighting settings can also be managed through the web driver. The 10,000mAh battery provides up to 500 hours with LEDs off and up to 100 hours with LEDs on. A full charge takes about 5 hours, and the wireless receiver is neatly stored near the kickstand on the back.
Less to Worry About in a Quiet Office with Lavenders
In an office, choosing a keyboard means thinking about the person in the next seat as well as my own hands. The ACH108 stock options are clearly aimed at that concern, and my first impression was exactly the quietness I associate with an office board. The Lavender switches also retain a tactile distinction. I like the idea that reducing sound doesn’t require the response under the fingers to become indistinct. It is a combination that makes particular sense in a study space, where even a small noise can draw attention. Someone who enjoys the sound of typing may want a different switch, but hot-swapping leaves that option open without replacing the keyboard itself.
Display Messages Change the Moment You Save
Type a phrase into the web driver, save it, and the keyboard reflects it straight away. The lack of a separate installation makes that process less burdensome on a work computer where adding programs may be awkward. It is a decorative function rather than a way to increase performance, yet that doesn’t make it pointless. The keyboard is something I look at every day. Letting a short line move across it gives a plain office desk a small change of mood. A Friday goodbye is one possible use, turning the board into a miniature sign as well as an input device.
Full-Size Layouts Can Feel Heavy on Cramped Desks
While the 108-key full layout is a huge advantage for those who need a number pad, office desks are generally tight on space. If you are coming from a tenkeyless (TKL) keyboard, you might find that it takes up quite a bit of desk footprint. The lack of a dust cover in the package is also a bit disappointing for office use. If your workspace is prone to dust accumulation, it is best to grab a separate cover. I recommend reconsidering your layout needs if you do not use the number pad frequently.
Abko ACH108 Pros and Cons
Pros
- Dot matrix display for scrolling custom text
- Three space-inspired colorways
- Two silent switch options tailored for noise-sensitive spaces
Cons
- F1 to F12 keys feature zodiac constellations instead of text (stylized somewhat awkwardly, possibly due to AI generation)
- No dust cover included in the box
Being Quiet Doesn’t Mean Having a Small Presence
Quiet typing doesn’t require the rest of the desk to lose its character. Here, a line of moving text can express the mood of the day while the switches keep the sound down. That combination is the point of the design for me. The keyboard still offers something to notice and talk about, even in a space where making noise is unwelcome. A small display isn’t a replacement for a comfortable layout or a suitable switch, but it adds a personal touch to equipment used throughout the day.
