Keychron K8 HE vs Logitech MX Mechanical: Which Keyboard to Buy?
Hall Effect TKL or quiet low-profile full-size? We compare the Keychron K8 HE and Logitech MX Mechanical on switches, connectivity, battery and build.
Short answer: get the Keychron K8 HE if you want a solid aluminum tenkeyless board with Hall Effect magnetic switches you can tune from 0.2 to 3.8 mm, Rapid Trigger and a 1000 Hz 2.4 GHz mode for gaming. Get the Logitech MX Mechanical if you want a quiet, low-profile, full-size keyboard that switches between three devices over Bluetooth or Logi Bolt.
Updated October 2026: this post originally covered the Keychron K8 Pro. Our current pick is the K8 HE, so the comparison has been rewritten around it.

Switches and typing feel
The K8 HE uses magnetic Hall Effect switches. Instead of a metal contact, a sensor reads how far the key is pressed, so you choose where it registers: as shallow as 0.2 mm or as deep as 3.8 mm. Rapid Trigger resets a key as soon as you start lifting it, which helps in fast games. Hot-swap is limited to Gateron double-rail magnetic switches.
The MX Mechanical uses low-profile tactile switches with a shorter press and a flatter, laptop-like feel. They are quiet enough for open offices, but they are not hot-swappable.
Connectivity
Both are wireless and multi-device. The K8 HE offers 2.4 GHz, Bluetooth for up to three devices, and USB-C wired. It polls at 1000 Hz on 2.4 GHz and wired, but 125 Hz on Bluetooth, so use the dongle or cable for gaming. The MX Mechanical pairs with three devices over Bluetooth or a Logi Bolt receiver.
Build, layout and battery
The K8 HE has a full aluminum frame and shine-through double-shot PBT keycaps. It is heavy at about 1.2 kg (2.6 lb) and has no number pad. Its 4,000mAh battery is rated up to 110 hours with the backlight off.
The MX Mechanical is full-size, so you get a number pad but a wider footprint on small desks. Its backlight adjusts to ambient light, and it is rated about 10 days with the backlight on.
Who should buy which
- Buy the Keychron K8 HE if you want one board for work and games, like a heavy aluminum build, and want to tune actuation.
- Buy the Logitech MX Mechanical if you share a room or take calls, move between a laptop, desktop and tablet, and want a number pad.
- On a budget? The Royal Kludge RK61 is a 60% wireless board with Bluetooth, 2.4 GHz and wired modes for much less. See all mechanical keyboards we compared.

Yes, but only with Gateron double-rail magnetic switches. It does not take regular MX-style mechanical switches. The MX Mechanical is not hot-swappable at all.
Which is quieter for an office?
The MX Mechanical. Its low-profile tactile switches are designed for quiet office typing, and it has an adaptive white backlight.
Which has better battery life?
They are rated differently. The K8 HE's 4,000mAh battery is rated up to 110 hours with the backlight off. The MX Mechanical is rated about 10 days with the backlight on.
Bottom line
The Keychron K8 HE is the more capable keyboard, with adjustable magnetic switches, Rapid Trigger and a 1000 Hz wireless mode in an aluminum TKL body. The Logitech MX Mechanical is the calmer office tool: quiet, low-profile and built for switching between devices.
