What will you mostly use it for?
The Keychron K15 Pro is the more versatile choice, winning or tying in most categories. Its Alice layout provides clear ergonomic benefits for office work and content creation, while its knob and high customizability score make it a strong pick for gaming and modding. The K3 V3 only wins outright for travel due to its lighter weight and smaller size, but ties in the programming category because both keyboards share strong QMK/VIA support.
Pick the Keychron K15 Pro
- Includes a dedicated rotary encoder knob, which can be programmed for in-game volume or macros via QMK.
- Higher productivity and customizability scores relative to its price tier suggest strong features for gaming setups.
- Available with Gateron low-profile mechanical switches in linear (red), tactile (brown), and clicky (blue) options.

Keychron K15 Pro vs K3 V3: your questions
The Keychron K15 Pro features a unique Alice layout, which is designed to place your hands in a more natural, angled position to reduce wrist strain. The K3 V3 uses a standard 75% layout, which does not provide this ergonomic benefit.
Yes, both keyboards fully support QMK firmware and VIA software, as confirmed by their specifications and vendor descriptions. This allows for extensive key remapping, macro creation, and customization of layers.
The Keychron K3 V3 is better for travel because it is lighter at 540 grams and has a smaller footprint (19 x 306 x 116 mm) compared to the K15 Pro, which weighs 696 grams and is larger (12 x 370 x 143 mm).
The K3 V3 comes with LSA profile shine-through ABS keycaps, which allow RGB light to pass through the legends for a vibrant effect. The K15 Pro comes with double-shot PBT keycaps that are not shine-through, so the lighting only glows around the keycaps.
The K15 Pro is available with low-profile Gateron mechanical switches in red (linear), blue (clicky), and brown (tactile). The K3 V3 uses Keychron Milk POM switches, which are also low-profile and available in red (linear), brown (tactile), and banana (tactile).
The Keychron K15 Pro includes an aluminum rotary encoder knob that can be programmed using the Keychron Launcher web app. The Keychron K3 V3 does not have a built-in knob.
Both keyboards have a hot-swappable version available, allowing you to change switches without soldering. Both are only compatible with Gateron/Keychron low-profile mechanical switches, not low-profile optical switches.
Both are excellent for programming due to their QMK/VIA support and macro keys, resulting in a tie. The K15 Pro has a slight edge in ergonomics, while the K3 V3 may offer a more pleasant typing sound thanks to its enhanced acoustic foams (IXPE, EPDM, latex).
The Keychron K15 Pro has a larger 2000mAh battery, while the Keychron K3 V3 has a 1550mAh battery. This suggests the K15 Pro may offer longer use between charges, though exact battery life is not stated.
The Keychron K3 V3 supports a wide range of ISO layout options, including UK-ISO, German DE-ISO, Swiss-ISO, and Nordic-ISO. The K15 Pro is only available in an ANSI layout.
Both keyboards have a 1000 Hz polling rate in wired mode, as stated in their specifications. In wireless mode, both operate at a 90 Hz polling rate.
The Keychron K3 V3 is explicitly described as having enhanced acoustic foam, including IXPE, EPDM, and latex foam layers, for improved sound and comfort. The K15 Pro's vendor description does not mention specific acoustic foam layers.
