What if the keyboard on your desk is slowing you down and you have not noticed? Three compact boards keep coming up in the same discussion: the Keychron K2 HE, the Ajazz AK820 Pro, and the MK770. All three use a 75% layout, so they look similar at a glance. The differences are in switch design, software, and daily tasks. That is where the workflow split appears, and this comparison covers it.

Why These Three Boards Get Compared So Often
The 75% layout is the sweet spot for a lot of people. You keep the function row and the arrow cluster, you lose the numpad, and you get back desk space for a mouse. Because all three boards share that footprint, buyers treat them as interchangeable. They are not.
The K2 HE is a wireless Hall-effect board, meaning it uses magnetic switches instead of traditional metal contact switches. The AK820 Pro is a gasket-mounted mechanical board with a knob and a small display, aimed at value-conscious buyers. The MK770 is a wireless mechanical board built for people who split time between gaming and typing.
Same size, same general price neighborhood, three different design philosophies. If you want a broader picture of how small hardware choices reshape a workflow, a closer look at how a single internal change can alter the feel of a board shows just how much difference one component makes.
The Switch Technology Gap Is the Whole Story
Here is the part most spec sheets bury. The K2 HE does not use conventional switches at all. Hall-effect switches sense magnetic field strength, which means the keyboard can register a keypress at a depth you choose rather than a depth fixed at the factory. That principle is worth understanding on its own; the Hall effect sensing principle explains how a magnetic field generates a measurable voltage without any physical contact between parts.
In practice, adjustable actuation changes how a keyboard behaves under your fingers:
- You can set a shallow actuation point for fast gaming inputs and a deeper one to avoid accidental presses while typing.
- Rapid trigger resets a key the moment you release it instead of waiting for a fixed reset point, which matters for strafing and repeated taps.
- Per-key profiles let one board serve two very different jobs without swapping hardware.
The AK820 Pro and MK770 take the traditional route. Their switches actuate at a fixed point set by the switch itself. What you get instead is hot-swap support, so you can pull the switches and drop in different ones whenever your taste changes. That is a different kind of flexibility: physical rather than digital.
Neither approach is better in the abstract. One lets you tune behavior in software. The other lets you tune feel in your hands.
Software and Configuration: Where the Real Friction Lives
Adjustable actuation and rapid trigger do not live in the keyboard. They live in the configuration software, and that software is where workflow differences become obvious. (Galaxy z fold 8 vs pixel 10 pro fold design cameras software)
The K2 HE depends on Keychron’s web-based configurator to set actuation points and rapid trigger behavior. That is convenient because nothing needs installing, but it also means those headline features may behave differently depending on whether you are wired or wireless, and on which operating system you use. Anyone who has fought a keyboard app that refuses to save a profile knows the frustration.
The AK820 Pro and MK770 lean on their own vendor software for remapping, macros, and lighting. Boards in this class sometimes support open firmware, and the QMK firmware documentation is the reference point for what open-source remapping can do when a board supports it. It is worth checking per model before you buy, because support varies by revision. (USB-IF HID class overview)
A practical tip from people who configure boards for a living: set up your profiles on day one, before the honeymoon period ends. Most buyers never revisit the software after the first week, so whatever defaults you leave in place become your permanent workflow.
Typing Feel and Build: Gasket Mount vs Everything Else
The AK820 Pro’s calling card is its gasket mount. The plate floats on soft strips instead of being screwed rigidly to the case, which produces a softer, more cushioned bottom-out. If you type for six hours a day, that difference is not cosmetic. It changes how tired your fingers feel by late afternoon.
The K2 HE and MK770 are stiffer boards by comparison. They prioritize consistency and gaming response over a pillowy typing feel. Neither is unpleasant, but if your work is 90% writing, the gasket-mounted board will likely win you over in a week.
Then there is the knob and display on the AK820 Pro. A rotary knob mapped to volume or zoom is one of those features you miss the moment it is gone. The small display is more of a novelty, but it can show connection status or layer information at a glance.
The MK770 also carries a rotary dial and targets mixed use, with 2.4 GHz, Bluetooth, and wired connectivity. The K2 HE matches that multi-mode approach. On connectivity, all three are roughly comparable, which is why the decision usually comes down to switches and software rather than ports.
A Side-by-Side Comparison
| Feature | Keychron K2 HE | Ajazz AK820 Pro | MK770 |
|---|---|---|---|
| Layout class | 75% | 75% | 75% |
| Switch type | Hall-effect (magnetic) | Mechanical, hot-swap | Mechanical, hot-swap |
| Adjustable actuation | Yes, via software | No | No |
| Rapid trigger | Yes | No | No |
| Mount style | Stiffer plate | Gasket mount | Stiffer plate |
| Knob or dial | No | Yes, plus small display | Yes |
| Connectivity | Wireless, multi-mode | Wired/wireless variants | 2.4 GHz, Bluetooth, wired |
| Best fit | Gaming plus tunable typing | Long typing sessions on a budget | Mixed gaming and desk work |
Read that table as a set of trade-offs, not a scorecard. The board with the most checkmarks is not automatically the right one for your desk.
Matching Each Board to a Real Workflow
If you game and type on the same desk
The K2 HE is the obvious pick. Rapid trigger and per-key actuation are genuinely useful in fast games, and you can switch to a deeper, heavier typing profile for documents. The catch is that you must actually use the software. Buyers who never open the configurator pay for features they never touch.
If you write for a living
The AK820 Pro makes a strong case. The gasket mount softens long sessions, hot-swap switches let you chase the exact feel you want, and the knob earns its place every time you adjust volume without looking. The display is optional gravy.
If you want one board for everything
The MK770 sits in the middle by design. It handles gaming and typing competently, offers three connection modes, and does not demand that you learn a configurator to get value from it. It is the least fussy of the three.
A common mistake across all three: buying on switch sound alone. Sound is the easiest thing to demo and the least predictive of daily satisfaction. Weight, actuation depth, and software reliability matter more after week two.
What Changes by 2027
Any 2027 buying advice carries a caveat. Firmware updates, new revisions, and discontinuations can reshape this comparison fast. Hall-effect boards in particular are evolving quickly, and features that require vendor software today may become standard or may fragment across models.
The safer way to plan is to buy for the workflow you have now and treat firmware as a bonus. A board that fits your hands and your software habits today will still fit them in two years. A board bought for a promised update is a gamble. The same logic applies to any hardware purchase weighed against a timing question: buy for current needs, not rumors.
It also helps to watch how adjacent tools evolve. Workflow thinking now spans hardware and software together, and tiered software comparisons follow the same pattern: the tier you pick should match the tasks you actually do, not the feature list you admire.
Practical Setup Tips That Actually Work
- Configure profiles before your first full workday. Set a typing profile and a gaming profile on the K2 HE, or a macro layer on the AK820 Pro and MK770.
- Test wireless and wired modes separately. Latency and feature support can differ between them.
- Keep your switch puller and spare switches handy if you buy a hot-swap board. Most people swap within the first month and then never again.
- Clean the plate and stabilizers quarterly. Gasket-mounted boards collect dust around the soft strips.
- Write down your custom mappings. Vendor software is rarely portable between brands, and a reinstall can wipe a profile you spent an hour building.
Conclusion
The K2 HE, AK820 Pro, and MK770 share a layout but not a purpose. The K2 HE is for people who want their keyboard to adapt through software, with adjustable actuation and rapid trigger doing the heavy lifting. The AK820 Pro is for people who want their keyboard to feel right in their hands, with a gasket mount, hot-swap switches, and a knob that earns its keep. The MK770 is the pragmatic middle, competent at everything and fussy about nothing.
Pick based on the work you do most, not the spec that looks best on paper. Then set it up properly in week one, because the workflow differences only show up after the novelty wears off.
Frequently Asked Questions
What is the main difference between the K2 HE and the other two boards?
The K2 HE uses Hall-effect magnetic switches with adjustable actuation and rapid trigger, configured through software. The AK820 Pro and MK770 use traditional mechanical switches with fixed actuation but support hot-swapping, so flexibility comes from changing hardware rather than settings.
Is rapid trigger actually useful outside of gaming?
It is most useful in games that reward fast repeated inputs. For typing, a shallow actuation point can speed up keystrokes, but many typists prefer a deeper setting to avoid accidental presses. The feature is only as good as the profile you build around it.
Does a gasket mount really make a difference for long typing sessions?
Many typists report a softer, less fatiguing bottom-out on gasket-mounted boards like the AK820 Pro. The effect is real but personal. If you bottom out hard on every keystroke, you will notice it more than a light typist will. (Iphone 17 pro vs pro max real differences size battery)
Do I need vendor software to use these keyboards?
No for basic typing. Yes if you want adjustable actuation, rapid trigger, macros, or custom lighting. The K2 HE’s headline features depend on Keychron’s configurator, while the other two use their own apps for remapping and macros.
Can I change the switches on all three boards?
The AK820 Pro and MK770 support hot-swap, so you can pull and replace switches without soldering. The K2 HE uses magnetic switches, which are a different ecosystem, so plan on sticking with compatible Hall-effect switches rather than standard mechanical ones.
Will these boards still be worth buying in 2027?
They should remain capable for their core jobs, but firmware support and revisions can change the picture. Check current release notes before buying, and favor the board that fits your workflow today rather than one bought for a future update.
