| Pros , different | 2.4 GHz, Bluetooth and wired connectivity (maker) QMK with PBT keycaps 96% layout with a numpad Battery rated up to 190 hours Siblings were praised for build and sound dampening (MakeUseOf, Tom's Guide) | Three connection modes: 2.4 GHz, Bluetooth 5.1 (three devices) and wired, with 1000 Hz on 2.4 GHz and wired Muffled sound with little case resonance from layered foam and a double-gasket design (AppleInsider) Thick aluminum shell that XDA Developers says will not move on the desk; Keychron lists 1,724 g PC plate, hot-swap sockets for 3-pin and 5-pin switches, QMK/VIA and a knob Gateron Jupiter Red, Brown or Banana switches come pre-installed on the assembled version 4000 mAh battery, rated up to 180 hours by Keychron |
| Cons , different | No K4 Max review was found, so feel is inferred from siblings ABS body and heavy at about 1290 g 1000 Hz polling, where the Ultra 8K offers 8 kHz No knob Tray mount is not stated on the maker's page | No adjustable feet; the angle is fixed at 5.2 degrees (AppleInsider) Wirecutter criticises the tall keycaps and the steep, non-adjustable case slope Keychron's 1000 Hz rating applies to 2.4 GHz and wired; the sibling Q1 HE drops to 90 Hz on Bluetooth (Tom's Guide) Heavy at about 1.7 kg, so not a portable 75% Wirecutter notes it costs more than its own upgrade pick, and AppleInsider's headline calls it costly |
| Research take , different | The dongle-equipped 96% K4. Reasonable pick, though evidence is inferred. | The most complete mechanical 75% in the Q line: reviewers praised the build, the sound and the 2.4 GHz option. The tall caps and fixed slope are the recurring complaints, so a wrist rest is worth budgeting for. |
