If you want

  • ISO layout options include ISO-UK, ISO-DE, ISO-SW, and ISO-Nordic.
  • Aluminum plate and additional EPDM foam, as described by Keychron.
  • Lighter 540g body with listed dimensions of 19 x 306 x 116 mm.

Bottom line

Choose the K15 Max if you want an Alice layout, 2.4 GHz connectivity, and the vendor-described IXPE and latex foam layers. Choose the K3 V3 if ISO layout availability, its aluminum plate, and its lighter, smaller body matter more. Both list QMK, VIA, and hot-swap support, so those shared features do not separate them.

Best for

What will you mostly use it for?

The K15 Max has the stronger case for gaming when wireless use matters, because it explicitly combines 2.4 GHz with a 1000 Hz polling rate. The K3 V3 is the more portable pick by listed dimensions and weight, and its ISO variants widen the layout choice. Office and content-creation preferences split between the K15 Max's Alice layout and extra wireless option and the K3 V3's smaller body. For programming and modding, both offer QMK, VIA, and hot-swap support, so layout preference is the deciding distinction.

For gaming

Pick the Keychron K15 Max

  • The K15 Max supports 2.4 GHz wireless at a stated 1000 Hz polling rate.
  • The K3 V3 supports wired and Bluetooth connections, but its vendor description gives a 90 Hz polling rate in wireless mode.
  • Both list a 1000 Hz polling rate, though the K3 V3 vendor description specifies that figure for wired mode.

FAQ

Keychron K15 Max vs K3 V3: your questions

The K15 Max has an Alice layout and supports 2.4 GHz, Bluetooth, and wired connections. The K3 V3 has a conventional layout with ISO variants available, and supports Bluetooth and wired connections.

Yes, its metadata lists ISO, ISO-UK, ISO-DE, ISO-SW, and ISO-Nordic options. The K15 Max is listed as ANSI only.

Yes, 2.4 GHz is listed alongside Bluetooth and wired connectivity. Keychron describes its 2.4 GHz mode as having a 1000 Hz polling rate.

The K3 V3 is listed at 540g, while the K15 Max is listed at 700g. The K3 V3 also has the smaller listed dimensions.

No. Both compatibility listings specify low-profile switches and keycaps only, and say standard MX keycaps will not fit.

Both list hot-swappable support, but Keychron describes hot-swap as an option for specific versions. The K15 Max hot-swappable version is described for Gateron and Keychron low-profile mechanical switches, while the K3 V3 version is described for Keychron low-profile 2.0 mechanical switches.

The K15 Max is the clearer choice if you want 2.4 GHz wireless, which is listed with a 1000 Hz polling rate. The K3 V3 supports Bluetooth and wired connections, and Keychron specifies 90 Hz polling in wireless mode.

Both metadata listings include QMK and VIA support. Keychron also describes Launcher-based remapping and macro customization for each keyboard.

The K15 Max is the Alice-layout model. The K3 V3 is listed with a normal layout and multiple ANSI and ISO variants.

The K3 V3 compatibility listing warns that its north-facing LEDs can cause Cherry-profile keycaps to hit the switch housing. Its keycap compatibility rule also limits use to low-profile keycaps.

Keychron describes the K3 V3 as having shine-through ABS keycaps. The K15 Max is listed with PBT keycaps, and its vendor description says they are non-shine-through.

Keychron describes IXPE and latex foam in the K15 Max, and IXPE, EPDM, and latex foam in the K3 V3. The K3 V3 therefore has the additional EPDM foam layer described by the vendor.
