Which is better for programming?

The Q2. Its 65% layout keeps the arrow keys and top-level keys most editors rely on, and the knob can be mapped to volume or zoom. The Q4 forces arrow functions onto a layer.

Is the Q4 worth the extra over the Q2?

It isn't extra at list. The Q4 was $77.00 at eBay and the Q2 $79.99 at Amazon as of November 7, 2026, so the Q2 costs about $3 more and adds arrows and a knob. Buy the Q4 only for its smaller footprint or a price dip like the $55.96 on November 6.

Do both work with a Mac?

Yes. Both ship with Mac and Windows keycaps and run QMK. The Q2's spec sheet lists Windows only, but Mac keycaps are in the box.

Which has better build quality?

They are effectively the same: CNC 6063 aluminum case, double-gasket mount and steel plate on both. The Q2's larger case feels heavier and more solid in hand.

Can I change the switches on both?

Yes. Both have hot-swap PCBs that take 3-pin and 5-pin MX switches, so you can swap Gateron G Pro for other switches without soldering.

Neither is silent by default. The Q2 with blue switches clicks audibly; pick brown or red switches on either board for a quieter office setup.

Keychron Q2 Mechanical Keyboard vs Keychron Q4 QMK Custom Mechanical Keyboard

Both are wired, all-metal, hot-swappable Keychron Q-series boards with QMK firmware. The Q2 is the better pick for most people: its 65% layout keeps arrow keys and a programmable knob, and it costs $79.99 at Amazon as of November 7, 2026. The Q4 is smaller and cheaper only if you catch a dip — $77.00 at eBay as of November 7, 2026, and $55.96 on November 6 — but it drops the arrow cluster.

Today the Keychron Q4 QMK Custom Mechanical Keyboard costs $2.99 less at its best price.
