Overview
This review covers the Logitech G915 X — Slim wired gaming keyboard with linear red switches, sold in Japan under the model number G915X-LNBK. This version is wired over USB, uses the Japanese (JIS) layout, has linear red switches, and comes in black.
The listing is labeled 'limited' because it includes a wallpaper download bonus. In short, it's a strong choice if you want a slim, quiet, full-size JIS keyboard that never needs charging.
It's a poor fit if you want magnetic-switch features like Rapid Trigger, or if you like swapping keycaps.
The body is about 23mm thick; the listed dimensions are 22.6 x 475 x 150mm.
That is much lower than a typical mechanical keyboard. The switches are Logitech's own low-profile GL mechanical switches in the linear (red) version: 1.3mm actuation point, 45g operating force, and 3.2mm total travel.
The original G915 actuated at 1.5mm, so this model registers a keypress after a shorter push.
The top plate is sandblasted aluminum alloy, and the keycaps are listed as PBT. LIGHTSYNC RGB supports 16.8 million colors, and Logitech G HUB lets you set per-key lighting and sync it with games or audio.
The 'limited' part refers to the wallpaper bonus. The keyboard itself should be the same as the regular G915X-LNBK, but check the listing for what the bonus includes.
How the Low-Profile Linear Switches Feel
A 1.3mm actuation point and 45g force make these keys light and quick to trigger.
In FPS games, that means less finger travel for strafing and spamming abilities. The downside is that heavy typists, or people who rest their fingers on the keys, may get accidental inputs.
Expect a few days of adjustment, and you may notice typos more in everyday typing than in games.
Linear switches have no tactile bump and no click, so each key moves smoothly to the bottom. You won't hear the sharp click of a blue switch, but you will still hear the key bottom out and spring back.
Read 'quiet' in the product name as 'quieter than clicky switches.' It is not the same as dampened silent switches.
A slim keyboard keeps your wrist flatter, so it's comfortable even without a palm rest. On the other hand, if you're used to tall boards with deep travel, 3.2mm can feel shallow.
Most standard mechanical switches have about 4mm of travel.
Compatibility Guide
This isn't a component that depends on a socket or power supply. Compatibility comes down to four things: the port, the OS, the physical size, and the keycaps.
| Item | Detail | Common pitfall |
|---|---|---|
| Connection | Wired USB (USB-A) | USB-C-only laptops need an adapter or hub |
| OS | Windows 10/11, macOS 11+ | Full customization requires free Logitech G HUB |
| Size | 22.6 x 475 x 150mm | 475mm wide full-size board with numpad; leaves less mouse room on narrow desks |
| Layout | Japanese (JIS) | US-layout keycaps and settings don't carry over |
| Keycaps | PBT, GL-specific stems | Not compatible with standard MX-style keycaps |
The port is the easiest thing to overlook. Many thin laptops only have USB-C, so a USB-A keyboard won't plug in directly.
Adapters usually work, but hubs can cause unstable power, so plug into a port on the PC itself when you can.
macOS is supported, but the JIS legends are printed for Windows. Some keys won't match what's printed on them; for example, the Windows key position acts as Command on a Mac.
You may need to remap keys in G HUB or in macOS settings. Consoles and Linux aren't listed in the specs, so we can't vouch for them.
Product Info
Listed specs: 23mm thickness, 1.3mm actuation, 45g force, 3.2mm travel, GL Linear (Red) switches, PBT keycaps, wired USB-A, LIGHTSYNC RGB (16.8M colors), JIS layout, and Windows/macOS support.
The data lists 9 dedicated G-keys. The KEYCONTROL feature is described as allowing up to 15 commands per key.
As of August 2026, the price on Amazon Japan was ¥27,000. Prices change often with sales and stock, so check the listing before you buy.
It launched around 2024 and sits near the top of Logitech G's low-profile mechanical lineup. The warranty is listed as 2 years from the manufacturer, but confirm the terms.
Listed contents are the keyboard, a USB cable, documentation, and the wallpaper download code.
As of June 2026, Amazon Japan reviews averaged 3.8 out of 5 from 17 ratings.
That's too few to draw firm conclusions. For keyboards like this, low scores often come down to taste, such as the shallow feel of low-profile switches or whether the price feels justified.
Read the reviews with your own priorities in mind.
Compared With Alternatives
| Product | Approach | Difference from the wired G915 X |
|---|---|---|
| CORSAIR K100 AIR | Slim wireless | Wireless; a variant without kana legends exists |
| Keychron K10 HE | Magnetic switches, wireless | Rapid Trigger-style features; US layout |
| AULA Hero 68 HE | 60% magnetic, wired | Compact with fewer keys; 8K polling |
| CORSAIR K70 RGB MK.2 SE | Standard-height full size | Deeper travel; far more keycap options |
What sets the wired G915 X apart is the combination of a slim body, JIS layout, full size, and no battery. If you want a slim wireless board, look at the K100 AIR.
If raw response speed matters most, magnetic boards like the Keychron K10 HE or AULA Hero 68 HE are the better fit. If you care most about typing feel and customization, a standard-height board will likely satisfy you more.
Best Use Cases
- Gamers who want a slim board: The light, shallow 1.3mm / 45g keys are easy on your fingers during rapid inputs. Being wired, there's no wireless lag or dead battery to worry about.
- Anyone who needs a full-size JIS layout: The numpad and Japanese input keys let one keyboard handle work, spreadsheets, and gaming.
- Minimal desk setups: The 23mm aluminum body looks clean, keeps your wrists flatter, and runs on a single cable.
- People avoiding clicky noise: Linear switches without clicks are easier on others during calls or late at night than blue switches.
Before You Buy
No Rapid Trigger. GL switches are contact-based mechanical switches.
Unlike magnetic (Hall effect) switches, they can't change their actuation depth or reset the moment you release a key. If this matters to you in games like VALORANT or CS2, start with a magnetic board instead.
Not suited to keycap swapping. GL keycaps use a different stem from MX-style keycaps, so almost no aftermarket custom sets will fit.
If you like changing your keyboard's look over time, this is a real limitation.
Wired means wired. If you want wireless or a tenkeyless size, look at other models such as the G915 X LIGHTSPEED line.
Connection type and size differ between models, so double-check the model number (G915X-LNBK here).
'Quiet' is relative. The keys still make noise when they bottom out, so don't expect silence.
If you type late at night while on voice chat, you'll need a lighter touch.
Check the macro key layout. The data lists 9 G-keys, but the number and position of G-keys vary between series and generations.
If macros are your main reason for buying, confirm the layout in the product photos.
Few reviews. As of June 2026 there were only 17 ratings, not enough to spot any trend in defects or unit-to-unit variation.
If you can, try low-profile GL switches at a store before buying.
FAQ
Q. Does it work on a Mac? A.
Yes, macOS 11 and later are supported. The JIS legends are printed for Windows, though, so modifier keys take some getting used to.
Use G HUB for detailed settings.
Q. Wired or wireless version? A.
For a desktop setup, the wired version is enough, with no charging and no latency concerns. If you use your PC from a distance or switch between devices, the wireless LIGHTSPEED line fits better.
Q. Are red switches good for typing work? A.
Yes. At 45g they're light and don't tire your fingers over long sessions.
Because they actuate early, people who rest their fingers on the keys may see some accidental inputs at first.
Q. Can I use standard keycaps? A.
Not really. GL switches use their own stem shape, so most MX-compatible keycaps won't fit.
Plan to keep the included PBT keycaps.
Q. What's different about the limited edition? A.
The product name only mentions a wallpaper download bonus. The keyboard itself should match the regular G915X-LNBK, but check the listing for the bonus details.
