Keychron K4 — Which Version Is Actually Right for You?
The Keychron K4 is one of the most versatile keyboards in the Keychron range. It sits in a 96% layout, which means you get a full set of keys including the numpad, function row and navigation cluster, all in a footprint that is noticeably more compact than a traditional full size keyboard. For people who want everything a full size keyboard offers without the extra desk real estate, the 96% layout is one of the most practical compromises available.
What makes the K4 interesting right now is that it comes in two genuinely different versions, the K4 Version 3 and the K4 HE. These are not minor revisions of the same keyboard. They use different switch technology, different internal engineering and are aimed at different types of users. Understanding the difference between them is the most useful thing you can do before deciding which one to buy.
The 96% Layout — Who It Suits
Before getting into the two models, it is worth understanding why someone would choose a 96% layout in the first place.
A full size keyboard gives you everything, numpad, function row, navigation keys, arrow keys, all spread across a wide footprint. A tenkeyless removes the numpad and brings everything closer together. A 96% layout keeps the numpad but compresses the spacing between key groups so the overall keyboard is significantly smaller than a full size while retaining every key.
The result is a keyboard that suits people who use the numpad regularly but want to reclaim some desk space. Accountants, spreadsheet heavy workers, data entry professionals and anyone who has grown up using a numpad and does not want to lose it will find the 96% layout a more comfortable daily driver than going tenkeyless.
The trade-off is that the compressed layout can take adjustment. The navigation cluster and numpad sit closer together than on a full size keyboard, which can feel tight initially. Most people adjust within a week or two.
Keychron K4 Version 3 — What It Is
The K4 Version 3 is the latest iteration of Keychron's standard K4, rebuilt from the inside out with a focus on typing feel, sound profile and programmability.
The most significant internal changes from earlier versions are the acoustic foams. The Version 3 adds sound absorbing foam, IXPE acoustic foam, EPDM foam and PET foam in layers, which work together to dampen the sound of each keypress and give a more consistent, controlled typing sound. If you have ever typed on an older K4 and found it slightly hollow or rattly sounding, the Version 3 addresses that directly.
The keyboard uses Keychron's own Super Switch, available in red, brown and banana options. These are pre-lubed from the factory, which means you get a smoother keystroke out of the box without needing to lube the switches yourself. The Super Switch is rated for 50 million keystrokes and covers the main switch preference categories, red for linear, brown for tactile and banana for a lighter tactile option.
On the programmability side, the K4 Version 3 runs QMK firmware and works with the Keychron Launcher web app. This means you can remap any key, create macros, set up shortcuts and customise your layout without downloading software. Everything runs in the browser, which makes it accessible across Mac, Windows and Linux without any compatibility headaches.
Connectivity covers Bluetooth 5.2 with support for up to three paired devices and USB-C wired mode. Battery life is substantial, around 190 hours with backlighting off and around 100 hours at the lowest RGB brightness. The 1000Hz polling rate in wired mode keeps latency minimal.
The K4 Version 3 is available with either an ABS plastic frame or an aluminium frame. The aluminium version adds weight and a more premium feel, sitting at around 970 grams compared to 813 grams for the plastic version. Three typing angle options at 5, 8 and 11 degrees give you some ergonomic flexibility depending on your desk height and preference.
Keycaps are double-shot PBT in Cherry profile, which is a comfortable and durable option that resists shine and wear over time. The north-facing RGB comes with 22 backlight modes and full control over hue, saturation, brightness and effect speed.
The K4 Version 3 is priced at $209.90.
Keychron K4 HE — What It Is
The K4 HE is a fundamentally different keyboard despite sharing the same 96% layout and overall dimensions. HE stands for Hall Effect, referring to the magnetic switch technology at the core of this keyboard.
Traditional mechanical switches use physical metal contacts to register a keypress. When the switch is actuated, two contacts touch and complete a circuit. This works reliably but it means the actuation point is fixed, every key on a traditional mechanical keyboard actuates at the same depth, and there is inherent wear on the physical contacts over time.
Hall Effect switches work differently. Instead of physical contacts, they use magnets and sensors to detect how far a key has been pressed. There are no contacts to wear out. More importantly, the actuation depth is not fixed. You can set each key to actuate at any point between 0.2 and 3.8mm with 0.1mm precision. That level of control is not available on any traditional mechanical keyboard.
The K4 HE uses Gateron double-rail magnetic switches, which are pre-lubed and designed for exceptional stability and smoothness. The double-rail design reduces wobble compared to single-rail switches, which contributes to a more consistent keystroke feel across the board.
For competitive gaming specifically, the K4 HE introduces several features that are becoming increasingly important in high performance keyboards. Dynamic Rapid Trigger allows the keyboard to activate and deactivate keys based on actual movement rather than fixed points, meaning a key can reset and be ready to fire again the moment it starts moving upward rather than waiting for it to return to a specific height. This gives faster response times in rapid keypressing situations.
Last Keystroke Prioritization ensures that when two directional keys are pressed simultaneously, the most recently pressed key takes priority. This makes counter-strafing in games like Valorant more reliable and responsive. Snap Click gives deeper keypresses priority when two keys are hit at the same time.
Dynamic Keystrokes, referred to as DKS, allows you to assign up to four distinct actions to a single key based on how far it is pressed. A light press might walk a character, a deeper press makes them sprint, and releasing the key can trigger another action. This layered input system is genuinely novel and opens up control options that are not possible on standard mechanical keyboards.
Analog Mode translates keypress depth into variable inputs rather than simple on and off signals, which gives controller-like precision on a keyboard for games that support analogue input.
Connectivity on the K4 HE covers 2.4GHz wireless at 1000Hz polling rate, Bluetooth 5.2 and USB-C wired. The 2.4GHz connection is the primary gaming mode, offering the same latency performance as wired without the cable. Battery life runs to around 110 hours with backlighting off.
The K4 HE comes in a standard version with Cherry profile shine-through PBT keycaps and an aluminium frame, and a special edition with natural rosewood accents in two colourways, light wood on white and dark wood on black, with OSA profile PBT keycaps and aluminium plus wooden frames.
The K4 HE is priced at $319.90.
K4 Version 3 vs K4 HE — The Honest Comparison
The price difference between these two keyboards is $110. Whether that is worth it depends entirely on what you want from the keyboard.
The K4 Version 3 is the better choice if your primary use is typing, general productivity or programming. The QMK firmware and Keychron Launcher give you thorough programmability, the acoustic foam layers make for a pleasant typing sound, and the Cherry profile PBT keycaps are comfortable for long sessions. It is a genuinely well made keyboard at a fair price for what it delivers.
The K4 HE is the better choice if gaming performance matters to you, particularly competitive gaming where response time and input precision make a difference. The adjustable actuation points, Dynamic Rapid Trigger, Last Keystroke Prioritization and Analog Mode are features that have a real impact in fast paced games. If you do not play competitively or do not care about those features, you are paying for capability you will not use.
Both keyboards share the same 96% layout, similar dimensions, Bluetooth 5.2, QMK compatibility and Keychron Launcher support. Both use double-shot PBT keycaps and offer RGB backlighting with 22 or more modes. Both support Mac and Windows with included keycaps for each.
The meaningful differences are the switch technology, the gaming specific features on the HE, the acoustic foam layering on the Version 3, and the price.
Frequently Asked Questions
