Get the
Keychron K3 Pro
Normal Layout
- Available in multiple ISO layouts (UK, German, Nordic, French, Spanish) plus ANSI.
- Choice between shine-through ABS keycaps or double-shot PBT keycaps.
- Uses pre-lubed Gateron low-profile switches for a smooth feel.
- No rotary encoder knob included.
- Smaller 1550mAh battery compared to the K15 Pro's 2000mAh.

For most users, the Keychron K15 Pro is the stronger choice due to its ergonomic Alice layout, extra macro keys, and programmable knob that boost productivity and comfort. Pick the Keychron K3 Pro if you need a specific ISO layout or prefer a standard key arrangement that is easier to adapt to. Both are well-built low-profile mechanical keyboards with QMK and VIA support, so your decision ultimately comes down to layout preference versus ergonomic features.

What will you mostly use it for?
The Keychron K15 Pro takes the lead in most productivity-focused categories thanks to its ergonomic Alice layout, extra macro keys, and a programmable knob. The K3 Pro wins only in travel, where its standard layout offers simpler packing and familiarity. In modding, the two tie, as both offer hot-swap sockets and QMK/VIA support, though their low-profile nature limits some customization. Overall, the K15 Pro is better suited for users who value comfort and workflow efficiency, while the K3 Pro appeals to those who need layout flexibility and a more traditional typing experience.
Pick the Keychron K15 Pro
- The K15 Pro includes a knob that can be programmed for gaming macros or volume control.
- The K15 Pro has additional macro keys beyond the standard 75% layout.
- Both have 1000 Hz wired polling rate, so latency is similar, but the K15 Pro offers more programmable inputs.

“Bought it, even if not available in german QWERTZ Layout. But because of reprogrammabillity, that does not matter that much. The clickiness of the brown switches is on point. Big fan. I would really like to have not ansi style buyable Low Profile Double Shot…”
“The form factor is great, the board feels great to use, but unfortunately it drops inputs far too frequently. I bought the board about 6 months ago and it was immediately dropping inputs, it didn't happen frequently and I hoped it would get better. Keychron…”

“For anyone buying this, remember to toggle the switch to the correct operating system. Other than that, the feel is good and it comes with a good feature set for a low price”
“I was happy at the beginning but after few months of use I'm getting more and more frustrated. Keyboard just hangs sometimes and I'm not able to connect with BT. I use it to operate two laptops and using Fn+1 anf Fn+2 combination is great... when it works…”

Keychron K15 Pro vs K3 Pro: your questions
The Keychron K15 Pro features an Alice layout, which is designed to keep your wrists in a more natural, straight position and reduce strain. The K3 Pro uses a standard 75% layout without the split ergonomic curve, so the K15 Pro is better for users seeking ergonomic benefits.
Yes, both keyboards support Bluetooth 5.1 wireless connectivity and can pair with up to three devices. They also offer a USB Type-C wired connection with a 1000 Hz polling rate for lower latency in gaming.
Yes, both keyboards are QMK-compatible and support the Keychron Launcher web app and VIA software for remapping keys, creating macros, and adjusting settings. This allows extensive customization of key functions and layers.
The Keychron K15 Pro has a larger 2000mAh battery, while the K3 Pro has a 1550mAh battery. Based on battery capacity, the K15 Pro should offer longer runtime between charges, though actual usage varies with backlight and wireless settings.
Both keyboards use low-profile Gateron mechanical switches, available in linear (Red), tactile (Brown), and clicky (Blue) options. They are hot-swappable, but only compatible with Gateron and Keychron low-profile mechanical switches, not optical switches.
The K15 Pro comes with double-shot PBT keycaps that are non-shine-through. The K3 Pro offers a choice between shine-through ABS keycaps (for backlight visibility) and non-shine-through double-shot PBT keycaps, depending on the variant selected.
Yes, the Keychron K15 Pro features an aluminum rotary encoder knob that can be programmed via the Keychron Launcher web app to control volume, zoom, scroll, or other custom functions. The K3 Pro does not include a knob.
The K15 Pro is lighter at 696g compared to the K3 Pro at 930g, though the K3 Pro is slightly narrower. The K15 Pro's lighter weight makes it easier to carry, but neither includes a carrying case as standard equipment.
Yes, the K3 Pro includes keycaps for both macOS and Windows, with dedicated function keys for each OS. It also supports switching between operating systems and offers different keymaps for each platform via the Launcher web app.
Both keyboards are 75% size. The K15 Pro is available only in ANSI layout, while the K3 Pro offers both ANSI and multiple ISO layouts including UK, German, Swiss, Nordic, French, and Spanish. This makes the K3 Pro more accessible to international users.
Yes, both keyboards are available in hot-swappable versions, allowing you to change switches without soldering. However, they only support Gateron and Keychron low-profile mechanical switches, not standard MX or optical switches.
Both offer over 22 RGB backlight settings and a static white option. The K3 Pro uses south-facing RGB LEDs to avoid interference with Cherry-profile keycaps, while the K15 Pro uses north-facing RGB. The choice depends on keycap compatibility preference.
