our Verdict
Top experts adored the Keychron K4, and recommended it for gamers, office users, and programmers. Reviewers at Android Central were amazed by its excellent build quality. Testers at Apple Insider say that it inclines between 0° and 8°. However, this model lacks a wrist rest.
Testing revealed that it has white backlighting with individually lit keys. Users who prefer RGB backlighting should check out the Keychron K6 review. Testing on a model with LK Optical Brown switches, analysts found that the keyboard requires a 58gf operating force and 1.9 mm pre-travel distance. This particular variant was quiet, and the typing was great during testing. However, if you prefer low-profile switches, explore the Keychron K3 review.
The K4 supports both wired connectivity and Bluetooth, pairing with up to three different devices at the same time. It has a rechargeable battery, which runs for up to 72 hours, according to Keychron. However, it’s not macro-programmable, and testers recorded an 11.1 ms wired latency and a disappointing 23.3 ms Bluetooth latency during their experiments.

| True Score | 80 | 80 | ||
| Market Context | – | The Keychron K4 is very similar to the Keychron K6, with both keyboards supporting USB and Bluetooth multi-device pairing. Both keyboards also have mechanical switches. However, the K6 has a lower 7.7 ms wired latency that provides faster gaming than the 11.1 ms latency of the K4. On the other hand, the K4 has a slightly lower 23.3 ms Bluetooth latency, beating the 27.1 ms Bluetooth latency of the K6. | Being an almost full-size keyboard (96%), the Keychron K4 has more keys, including a number pad and dedicated arrow keys, than the compact 60% RK61. Unlike the K4, the RK61 is hot-swappable, allowing users to replace the switches without soldering. | Consumers typically consider the Keychron K4’s competitor, the Logitech MX Keys. These two keyboards are both wireless models that support multi-device Bluetooth pairing. However, the Logitech has low-profile scissor switches, while the Keychron features higher-profile mechanical switches. |
