I tried the Keychron K2 HE and loved its magnetic switches

Best Prices Today: Keychron K2 HE

The Keychron K2 HE combines reverb impact expertise with a compact 75 % format. Designed for avid gamers, it must also carry out effectively within the workplace. We examined its design, construct high quality, options, switches, gaming efficiency, and on a regular basis usability.

Keychron K2 HE: Design and workmanship

The Keychron K2 HE is obtainable both in black or as a particular version with wood sides. We examined the latter model. The actual wooden aspect panels are neatly fitted, really feel easy and provides the keyboard a heat, nearly cozy look.

Transitions and gaps are constant, nothing creaks and the aluminum body enhances the high-quality look. Thanks to its weight of just below one kilogram (965 grams), the board may be very secure on the desk. The 75 % format saves house whereas retaining the arrow keys and an important navigation row.

The building is powerful: an aluminum body on the prime (“aluminum top frame”) retains the keyboard inflexible, a metallic help plate beneath the keys (“plate”) stabilizes the switches, and several other damping layers soak up vibrations.

The so-called “tray-mount” design signifies that the circuit board and plate are screwed into the underside tray, which ensures a direct, fairly agency typing really feel with little resonance. The acoustics are muted (“thockig”), mechanical background noise is saved to a minimal. However, we suggest a palm relaxation for extended use because of the peak of the casing–this isn’t included and is subsequently a minus level.

Keychron K2 HE: Features and expertise

The Keychron K2 HE can be utilized by way of cable and wirelessly. Using USB-C and a 2.4 GHz dongle, you possibly can obtain a polling charge of as much as 1,000 Hz for quick, secure enter. Bluetooth 5.2 connects as much as three units on request, however is noticeably slower, making it extra appropriate for workplace and multi-device use.

Inside is a 4,000 mAh battery that lasts from a number of days to a number of working weeks, relying on the lighting and utilization profile. The non-slip PBT keycaps can be found in ANSI or ISO format, relying on the variant.

However, the hot-swap system (buttons could be modified with out soldering) is proscribed to Hall-effect switches of the Gateron Double-Rail kind; basic MX switches don’t match.

Practical for on a regular basis use, you possibly can swap between Windows and macOS key assignments utilizing a slide swap, and Keychron contains appropriate mod keys. Dedicated media keys or a quantity knob are lacking; management is by way of Fn combos or remapping within the software program.

Keychron K2 HE: Technical specs

The Keychron K2 HE makes use of Hall-effect switches, the place a magnetic sensor detects the keystroke. This permits the set off and reset level to be finely adjusted for every button.

The “Rapid Trigger” expertise refers back to the quick automated reset instantly after launch–supreme for fast follow-up entries. “Multiple Actuation/Dual-Action” permits totally different actions relying on the depth to which a secret is pressed, whereas “Last-Key-Priority” prioritizes the final key pressed throughout simultaneous inputs.

The built-in RGB lighting provides quite a few results and infinitely variable brightness.

Everything is managed by way of the Keychron Launcher, a web-based app for key assignments, macros, lighting, and fine-tuning the reverb impact switches. The keyboard saves profiles internally, however the USB cable is briefly required to use modifications.

Keychron K2 HE: High-end switches

The factory-lubricated linear switches of the “Gateron Double-Rail Nebula” kind run very easily. The POM plunger with double-rail information ensures excessive stability and minimal lateral wobbling. The launch is freely selectable by way of software program, from 0.2 to 3.8 mm in 0.1 mm increments.

The spring is within the mild vary with a beginning drive of round 40 grams, the bottom-out is round 60 grams. The whole journey is round 4.0 mm. The switching traits are roughly akin to the Cherry MX Red.

The typing really feel stays delicate and quiet, supported by the housing damping. Large keys are effectively stabilized, and the house bar, for instance, can be additional damped. The stabilizers themselves are additionally lubricated for higher acoustics and actuation.

Keychron K2 HE: Gaming efficiency

The Keychron K2 HE exhibits its strengths in 2.4 GHz and cable operation: low latency, 1,000 Hz polling (1-ms sign charge) and quick resetting because of Rapid Trigger. In sensible phrases, which means the buttons set off very early and are instantly prepared to be used once more after minimal launch.

For shooters, we suggest a set off journey of 1.2 to 1.5 mm on WASD and an RT hysteresis (the quick reset journey that the button requires after launch till it triggers once more) of 0.1 to 0.2 mm. “Counter-punishments” and high quality corrections are thus extra secure.

In our opinion, the house bar–for instance, for leaping–can set off even flatter (approx. 0.8 to 1.0 mm), whereas skills or reloading are intentionally decrease (approx. 1.8 to 2.2 mm) in an effort to keep away from incorrect inputs.

“Last-Key-Priority” prevents “stuck” inputs when altering path concurrently. The K2 HE processes N-key rollover (NKRO) with out ghosting; quick double-taps and micro-corrections stay cleanly reproducible.

With “Multiple Actuation/Dual-Action,” you possibly can assign two actions to at least one key–for instance, mild press = stroll, deep press = run or create, after which zoom on the identical key. For rhythm/motion video games, the triggering per button could be very finely staggered; in our testing, quick response chains had been noticeably simpler to time with Rapid Trigger.

Bluetooth is noticeably slower (typical 125 Hz sign charge) and isn’t really useful for aggressive gaming; there may be sometimes a brief “wake-up second” after standby. BT is adequate for single-player video games, streaming PCs, and workplace work.

For gaming, you must use 2.4 GHz or USB-C. Practically, within the Keychron launcher, it can save you profiles with totally different set off depths and dual-action assignments for every recreation and cargo them rapidly if wanted.

Keychron K2 HE: Everyday work

Quiet operation, compact dimensions, and dependable multi-device dealing with make the Keychron K2 HE appropriate for on a regular basis use. The PBT keycaps are non-slip and resist shiny spots. The 75 % format takes some getting used to, however provides a very good stability of space-saving and direct entry.

Keychron K2 HE: Battery life

Depending on the brightness and mode, the board can comfortably final one to 2 working weeks in blended use. Heavy RGB use and pure Bluetooth operation noticeably shorten the runtime. On the constructive aspect, the board additionally maintains 1,000 Hz efficiency wirelessly by way of 2.4 GHz.

Keychron K2 HE: Software

As the Keychron launcher is an online app, you don’t want to put in something. Simply plug within the Keychron K2 HE by way of USB-C, permit the browser to entry the gadget and customise key assignments, macros, lighting, and the reverb impact parameters. The keyboard saves these profiles internally, they usually additionally apply in 2.4 GHz and Bluetooth modes.

In apply, the set off, reset level, and speedy set off can solely be modified by way of USB; there are not any direct shortcuts for this on the keyboard itself. Light, brightness, and impact modifications, however, work instantly by way of Fn combos.

Two profiles are really useful: a gaming profile with a flat set off and an workplace profile with a deeper set off journey and quiet lighting. Frequent remaps embody Caps Lock to Ctrl or media capabilities on the arrow keys. Macros can set off command sequences corresponding to “mute mic and push-to-talk.”

The launcher works on Windows and macOS, and normally additionally on Linux, supplied the browser helps WebHID. Transferred modifications take impact inside a number of seconds after which run autonomously on the keyboard. Input latency stays unchanged. Dedicated controls, corresponding to a quantity knob, are lacking; media management is dealt with by way of Fn ranges or remapping.
