This Keychron Keyboard Combines One of the Best Technologies in Gaming With a Gorgeous Premium Design
Keychron delivers yet another fantastic keyboard with the K4 HE, this time with a new gaming technology.
If you’ve paid any attention to gaming accessories the past few years you’ve likely heard something about the benefits of Hall Effect joysticks and triggers. Essentially, instead of using a physical connection to sense movement, Hall Effect sensors use magnets. The idea is to reduce wear and tear on components to give you more durability as well as improve the controller’s response time. Most gamers probably won’t notice the difference between a standard and Hall Effect controller, but for the hardcore gamers, where every millisecond counts, it can make a big difference.
Hall Effect controllers have exploded in popularity over the past few years, so I suppose it was only a matter of time before companies started using this same technology in keyboards. Behold the Keychron K4 HE: It’s a 96%-sized wireless keyboard from the world-renowned company. As you probably guessed from the intro, it uses uses Hall Effect switches instead of traditional mechanical switches. The result is a combination of superlatives like impressive, enjoyable, annoying and ridiculous overkill, all in one package.
What I like about the Keychron K4 HE
For starters, the build quality is exceptional, as I’ve come to expect from Keychron. The K4 HE has a good bit of weight to it, which gives it a premium feel, and the wood sides of the Special Edition version I reviewed add a touch of luxury as well. It’s available with either black or white keycaps with slightly different wood tones for each. There’s also a Standard version, which has Cherry-profile keycaps instead of OSA-profile and loses the wood side rails, knocking about $10 off the price.
The most important feature of the K4 HE, however, is the Hall Effect switches. The use of magnets enables a 0.2 to 3.8mm actuation range with a minimal 0.1 mm sensitivity. The Nebula Gateron switches that came with my K4 HE have a start and end actuation force of 40 gram-force and 60 gram-force, respectively, but you can get other Hall Effect switches with smaller or larger actuation forces. It’s worth noting that the K4 HE is only compatible with double-rail magnetic switches. So while you can hot-swap the switches, you cannot use traditional mechanical switches.
What’s really nuts is the insane levels of software customization available. You can set different actions for different actuation points within each keypress, meaning a shallow, 0.2mm keypress could trigger one action while a deeper, 3.8mm keypress could trigger a different action. There’s also Last Key Prioritization, which prioritizes the last key pressed, and Snap Click, where deeper keypresses take precedence when you press two keys at the same time. Basically, this allows you to trigger multiple actions in a game without having to lift your fingers for multiple keypresses. In games that require speed and fast reaction times, this can be huge.
The Rapid Trigger feature also gets a speed boost because each keypress is reset the moment the key travel reverses, meaning you can keep firing or moving literally as fast as your finger can move. Honestly, the most surprising thing to me is that you can have up to four distinct actions per key based on how hard you press it. As in, you can program up to four stages per key, which triggers a keypress at each stage.
This is my first experience with Hall Effect magnetic keyboard switches and the typing experience is… interesting. Fully aware of the irony, I immediately noticed how firm and tactile the typing experience felt when I first started using it. The design engineers at Keychron deserve a lot of credit for tuning the magnetic resistance so superbly. It feels amazing to type on.
The acoustics are also enjoyable. While they don’t quite have the crispiness of a traditional mechanical keyboard «thock,» they still sound great. I personally enjoy the noise of a mechanical keyboard and the K4 HE sounds nice to my ears. The only exceptions are the spacebar and other longer keys. It’s not unusual for these specific keys to sound different than the rest of the keyboard, but it’s still annoying when they do, at least for me.
HE not for everyone?
I never quite got used to the typing experience over my several weeks with it, so I never got back up to my normal typing speed and accuracy while using it. I still haven’t decided if I’m going to press on (sorry) and see if I fully adjust or go back to my standard mechanical switches. Part of my frustration lies with the compact layout. It’s literally one solid rectangle with no space between the main keyboard and the arrow keys, numpad, or function keys. I personally found it annoying and don’t know if I’ll get used to it.
Also, if you’re a big fan of RGB, I’d probably get the Standard edition over the Special Edition because the RGB is much harder to see with the keycaps from the Special Edition.
Overall, the Keychron K4 HE is an impressive keyboard. If you are a hard-core FPS player, there’s no doubt you can take full advantage of the customization options to up your gameplay, and the solid build quality and wood rails look great on any desk. If you don’t need a numpad, I’d probably recommend going for the K2, as the layout is likely closer to what you’re used to.
Either way, for $135 to $145, depending on if you want the OBS keycaps and wood rails, there’s not a lot wrong with the K4 HE. That’s a good price for a keyboard this good, and if it sounds interesting to you, you won’t be disappointed.

Google races to put Gemini at the center of Android before Apple’s AI reboot
Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.
Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’
Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.
Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge
Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.
Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.
Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.
The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.
The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.
Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.
Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.
Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
