Compare Keychron K15 Max vs Q15 Max Ortholinear Differences Side by Side

This comparison is for buyers choosing between two wireless Keychron boards with hot-swap support, QMK, and wired, 2.4 GHz, and Bluetooth connectivity. The K15 Max pairs a low-profile Alice layout with a 75% footprint, while the Q15 Max uses a compact ortholinear layout with a 65% size classification. The Q15 Max adds an aluminum case, polycarbonate plate, and knob support, while the K15 Max is lighter and explicitly lists VIA support. The right choice depends more on layout preference and physical design than on their overlapping core features.

Pros and Trade-offs

Pick the K15 Max if you want a low-profile Alice layout, a specified 700 g weight, and both QMK and VIA listed. Choose the Q15 Max if ortholinear keys are your preference and you value its aluminum case, knob support, broader stated switch-socket compatibility, or larger battery. Check the exact K15 Max variant before buying if switch swapping is important.

Which Keyboard Is Better for Your Needs?

The K15 Max is a more straightforward pick for buyers who want a low-profile Alice keyboard with VIA listed alongside QMK, while the Q15 Max better fits users committed to an ortholinear layout. The Q15 Max stands out for hardware customization details, including 3-pin and 5-pin switch support, its plate and foam layers, and knob support. For travel, its larger listed battery is an advantage, though the K15 Max has a specified weight and the Q15 Max does not.
