Keychron K13 Max vs K15 Pro80% Numpad or Alice Ergo

No, both keyboards are designed exclusively for low-profile switches. The vendor pages for both state they are only compatible with Gateron/Keychron low-profile mechanical switches. Standard Cherry MX switches have a different height and pin design and will not fit the hot-swap sockets.

No, the K15 Pro does not have a 2.4 GHz wireless mode. According to the vendor description, it connects wirelessly via Broadcom Bluetooth 5.1 and offers a wired USB Type-C connection. For a 2.4 GHz option, you would need to consider the K13 Max.

The Keychron K13 Max is the better choice for quiet typing. Its vendor description specifically mentions advanced IXPE acoustic foam and resilient latex foam installed inside the case to reduce noise and improve the typing sound. The K15 Pro's listing does not mention any specific acoustic foam.

Yes, both the K13 Max and the K15 Pro support QMK and VIA firmware, according to their metadata. This allows for extensive key remapping, macros, and custom shortcuts via the Keychron Launcher web app. You need to connect the keyboard via a wired USB cable to use the Launcher.

Yes, the vendor description for the K15 Pro states it offers a Mac layout with the same multimedia and function key functions as Apple keyboards. It also includes keycaps for both macOS and Windows, and you can configure different keymaps for each operating system.

The Keychron K15 Pro is more compact due to its 75% Alice layout, which is narrower than the 80% layout of the K13 Max that includes a full numpad. The K15 Pro's dimensions (370 x 143 mm) confirm it has a smaller footprint compared to the K13 Max (346 x 119 mm, though it is slightly longer).

Both keyboards come with low-profile double-shot PBT keycaps. The K13 Max vendor page describes them as durable, non-shine-through PBT material with oil resistance. The K15 Pro description also mentions non-backlight shine-through PBT material. Neither offers shine-through keycaps standard.

Yes, the K13 Max is well-suited for gaming. It supports a 1000 Hz polling rate on both its 2.4 GHz wireless and wired modes, which is explicitly marketed for competitive gaming. It also includes N-Key Rollover (NKRO) on both wireless and wired modes.

Yes, the K15 Pro features a programmable aluminum rotary encoder knob. According to the vendor page, it is designed to enhance creative workflows and can be customized to control functions like volume, zoom, or any other key or macro through the Keychron Launcher web app.

The Keychron K15 Pro is generally better for wrist pain due to its Alice layout. This ergonomic design places the hands in a more natural, slightly angled position, which can reduce strain. User reviews for the K15 Pro explicitly mention it helps with carpal tunnel pain.

The K13 Max has an 80% layout with a dedicated numpad, which is ideal for data entry. The K15 Pro has a 75% Alice layout, which is a split, ergonomic design without a numpad but with additional macro keys. The K13 Max is available in ISO layouts, while the K15 Pro is only available in ANSI.

Both keyboards offer a hot-swappable version as an option. The vendor pages for both the K13 Max and K15 Pro state that the hot-swappable version allows users to change low-profile Gateron mechanical switches without soldering. Note that they are only compatible with low-profile switches.
