FAQ

Keychron K3 HE vs K3 Max SE: your questions

The main difference is the switch technology. The K3 HE uses Keychron Ultra-Fast Lime Low-Profile magnetic switches with Hall Effect sensing, which allows adjustable actuation points and features like Rapid Trigger. The K3 Max SE uses Keychron Milk POM mechanical switches, which offer a traditional feel with linear, tactile, or banana options.

No, the K3 HE is only compatible with Keychron Ultra-Fast Lime Low-Profile magnetic switches. The hot-swappable design is tailored for magnetic switches, not standard mechanical ones like the Milk POM series found in the K3 Max SE.

The K3 Max SE has a longer battery life, rated at up to 120 hours from its 1550 mAh battery. The K3 HE offers up to 55 hours from its larger 2600 mAh battery, likely due to the additional power draw of its magnetic switch sensing technology.

Yes, both the Keychron K3 HE and K3 Max SE support triple connectivity through 2.4 GHz, Bluetooth 5.2, and USB-C wired modes. They also both offer a 1000 Hz polling rate in wired and 2.4 GHz modes, and 125 Hz in Bluetooth mode.

Yes, both keyboards support QMK and VIA for key remapping, macros, and customization. The K3 HE also offers additional magnetic-specific adjustments like actuation point tuning, which can be configured via the Keychron Launcher web app.

Both keyboards use LSA (low-profile spherical-angled) double-shot PBT keycaps that are not shine-through. They offer similar durability and oil resistance, though the K3 HE's keycaps are described as having a unique design for its magnetic switch model.

The K3 HE is generally better for competitive gaming due to its Hall Effect technology. It includes features like adjustable actuation points (0.2 to 2.9 mm), Rapid Trigger, Snap Click, and Last Key Priority (LKP) which allow for faster, more responsive inputs in games like Valorant.

The K3 HE weighs 575g, while the K3 Max SE weighs 566g (plus or minus 10g). The difference is minimal, but the K3 Max SE is slightly lighter, which could be a minor advantage for portability. Both feature a wood and plastic or aluminum construction.

Yes, both the K3 HE and K3 Max SE feature per-key RGB and mix RGB backlighting with 22+ settings, including a static white option. They both have north-facing RGB LEDs that can be customized through the Keychron Launcher web app.

Yes, the K3 Max SE offers a Mac layout while remaining compatible with Windows. It provides the same multimedia and function key functions as Apple keyboards for Mac users, similar to the K3 HE which is also compatible with macOS, Windows, and Linux.
