Keychron C2 フルサイズ 104キー 有線メカニカルゲーミングキーボード Macレイアウト用 Gateron G Pro ブラウンスイッチ

This article takes a closer look at the Keychron C2 フルサイズ 104キー 有線メカニカルゲーミングキーボード Macレイアウト用 Gateron G Pro ブラウンスイッチ, using its published specs, listed prices, and review data.

Overview

The Keychron C2 is a 104-key full-size wired mechanical keyboard built around Gateron G Pro Brown (tactile) switches, a white LED backlight, and double-shot ABS keycaps. It is laid out for macOS but ships with Windows keycaps too.

The short version: this is a board for people who do not need wireless or hot-swap, and simply want one solid, numpad-equipped keyboard on a stable wired connection.

Amazon.co.jp listing data shows 4.6 out of 5 stars across 482 reviews (captured July 2026), roughly a 92% positive score — strong for the entry-to-mid full-size tier.

The flip side is that it is not aimed at anyone who wants RGB effects or a cable-free desk. This article draws that line clearly.

Two rows matter most in practice: the 435 × 130 × 38 mm footprint, which decides how much desk it eats, and the fixed cable, which decides how much freedom you have in routing and repair. Both are covered below.

Compatibility Guide

Connectivity is USB Type-C wired only, using a braided USB-C to USB-A cable. Per the manufacturer's compatibility note, any PC or Mac with a USB-A port works with no driver installation.

It is not a high-draw device, so a powered or unpowered USB hub is normally fine.

The catch is the USB-A end. Many recent MacBooks and thin laptops only expose USB-C ports, so you will need a USB-C adapter or hub.

A USB-C connector on the keyboard side does not mean the bundled cable plugs straight into a modern Mac. Check your machine's ports before ordering.

On the OS side, both Mac and Windows keycaps are included, along with a Siri key (Mac) and a Cortana key (Windows). Note that Num Lock functions only under Windows; on macOS the numpad should be treated as always sending digits.

If you were counting on toggling numpad behaviour on a Mac, that is not available here.

The 435 × 130 × 38 mm size is typical for a full-size board but still significant on a small desk. No palm rest is included, and the 38 mm frame height means a separate wrist rest — or a lower desk position — helps during long sessions.

If you plan to use a keyboard tray, measure for the 435 mm width first.

Product Info

The Keychron C2 arrived around 2020 as a value-focused, wired-only model. Listed pricing on Amazon.co.jp was ￥14,299 as of July 2026 and ￥15,347 as of August 2026 — about ￥1,000 of movement in roughly a month.

That volatility is itself useful information: stock, exchange rates, and seller turnover all move this price. Treat any figure here as a snapshot and confirm the current price on the product page.

Review data stands at 482 reviews averaging 4.6 out of 5 stars (captured July 2026).

With a sample that large, early-unit issues and unit-to-unit variation are already averaged in, so the odds of drawing an outlier are low. The eBay entry is a search link only with no captured price, so if you are hunting used or parallel-import units you will need to check the going rate yourself.

In the box: a USB-C to A cable, a keycap puller, extra Mac/Windows keycaps, and a manual. The warranty is one year from the manufacturer, and the switches are rated for 50 million keystrokes — enough that full-time daily typing is measured in years, not months.

How It Compares

Within Keychron's own range, the C2 sits on the stripped-down side. The V and Q series add hot-swap sockets and QMK/VIA remapping, letting you change switches on a whim.

The C2 does neither. It is designed as an entry point for people who want to try mechanical without falling into the switch-collecting hobby.

On layout, the realistic comparison is against TKL, 75%, and 65% boards. In games where you sweep the mouse widely, the numpad's extra width is a direct disadvantage, so FPS-first buyers are better served by a compact layout.

Conversely, for spreadsheets, accounting software, or any numeric data entry, a dedicated numpad is something compact boards simply cannot replace. That is the single strongest reason to pick the C2.

As for feel, Gateron G Pro Brown is the classic tactile middle ground: a light bump without the sharp click of a blue switch. It is less glassy than a linear and far less noisy than a clicky.

For a shared office it is a much safer choice than blues — though any mechanical board is louder than a membrane or laptop scissor keyboard.

Best Use Cases

• Mac users who want a full-size mechanical. Legends and modifier placement follow the Mac layout, and the bundled Windows keycaps mean a later switch of platform does not waste the purchase. Full-size boards built Mac-first are not common, so this is a genuine advantage.
• Anyone doing numeric entry daily. Accounting, data entry, CAD coordinates — work where a dedicated numpad directly affects speed pairs well with tactile browns and 104 keys.
• First-time mechanical buyers on a budget. At ￥14,299 as of July 2026 (￥15,347 as of August 2026), you get 50-million-keystroke switches and double-shot ABS caps whose legends will not wear off.
• Desktop users who do not mind a cable. Being wired means no battery to track and one fewer source of latency. For a stationary setup it is not a drawback at all.

Things to Know Before Buying

There is no wireless at all. The C2 is USB-C wired only — no Bluetooth, no 2.4GHz dongle — and the cable is non-detachable (braided and sturdy, but fixed).

That means two things: you cannot pair it with an iPad or phone, and if the cable fails you replace the whole keyboard. Unlike boards with removable cables, there is no cheap way to extend its life, so route it without stressing the strain relief if you move it often.

The backlight is fixed white. No RGB, no colour changes, no lighting effects.

If the word "gaming" in the product name led you to expect RGB, this is where disappointment lands. For simply reading legends in a dim room it is perfectly adequate, but look elsewhere if lighting is part of the appeal.

No hot-swap, no macros. You cannot swap switch types without soldering, and there is no macro programming.

If you want either, Keychron's QMK/VIA-capable V and Q series are the right shelf. The C2 is meant to be complete as purchased.

The keycaps are ABS. Double-shot construction keeps the legends permanent, but ABS shines with use more readily than PBT.

Expect your most-used keys to develop a gloss within a year or two. Aftermarket PBT caps are an option later, since the Gateron stems are MX-compatible as a general rule.

Check the price and the seller. Listed prices moved from ￥14,299 (July 2026) to ￥15,347 (August 2026).

The seller and shipper is an import specialist shop (Hawaii Store) rather than the manufacturer or a major distributor, so warranty handling and local support terms may vary — confirm on the product page before buying. Also note that Amazon listing metadata sometimes disagrees with the actual item.

Verify the layout (US vs JIS) and switch colour against the product photos and title, not just the spec text.

Num Lock is Windows-only. On a Mac-centred setup, plan on the numpad always sending digits.

FAQ

Q. Can one unit serve both Mac and Windows? A.

Yes. Keycaps for both platforms are included, along with Siri and Cortana keys.

Num Lock, however, works only under Windows.

Q. Is it quiet enough for an office? A.

Gateron G Pro Brown is tactile, not clicky, so there is no sharp blue-switch click. It is still a mechanical board and louder than a membrane or laptop keyboard.

If silence is the top priority, look at silent switches instead.

Q. Can I change the switches later? A.

Not without soldering — the C2 is not hot-swappable. If switch swapping appeals to you, choose a hot-swap model instead.

Q. Is it good enough for gaming? A.

The wired connection removes wireless latency concerns and it handles general gaming fine. But there is no RGB, no macros, and no rapid-trigger-style competitive features, and the full-size width limits mouse room.

Competitive FPS players should consider TKL or smaller.

Q. How trustworthy is the rating? A.

4.6 out of 5 across 482 reviews as of July 2026 — a large enough sample to be meaningful.

Be aware that reviews may mix different layout variants, so check that a reviewer's version matches the one you intend to buy.

Q. Does it include a palm rest? A.

No. The box has the cable, keycap puller, extra keycaps, and a manual.

Given the 38 mm frame height, a separate wrist rest is worth adding for long typing sessions.
