Product Description

The Keychron One of Zero Si75 HE is a 75% mechanical keyboard designed for users who want highly customizable key responses and a versatile typing experience. It suits gamers needing precise, fast inputs and typists who value adjustable actuation points and sound dampening. Its magnetic switches and modular design offer flexibility but require some familiarity with advanced keyboard features.

Key Features

  • Uses magnetic Hall Effect switches that detect keypresses without physical contact, reducing bounce and chatter for smoother inputs.
  • Adjustable actuation points from 0.2 to 3.8 mm with 0.1 mm increments, allowing users to fine-tune key sensitivity for faster or more deliberate presses.
  • Dynamic Rapid Trigger activates keys based on travel distance, enabling immediate response and faster keystrokes, beneficial in fast-paced gaming.
  • Dynamic Keystrokes lets each key perform up to four different actions depending on press depth, adding layered control without extra keys.
  • Analog Mode provides variable input levels per keypress, similar to game controllers, for nuanced control in compatible games.
  • Hot-swappable magnetic PCB supports easy switch changes without soldering, increasing customization options.
  • Software allows remapping, macro creation, and profile switching saved directly on the keyboard.

Build Quality and Design

  • Frosted translucent ABS case combined with a white aluminum plate offers a balance of durability and lightweight feel.
  • Gasket mount design with silicone modules improves typing comfort by reducing vibrations and noise.
  • Includes sound dampening layers such as porous foam between PCB and plate, and PU foam under the PCB, lowering typing noise.
  • Comes with screw-in stabilizers for stable larger keys and 1.7 mm thick dye-sublimated PBT keycaps for durability and consistent texture.
  • Interchangeable colorful silicone modules and feet allow visual customization and typing angle adjustments (3.5° or 6.5°).

Compatibility and Connectivity

  • ANSI layout with 81 keys supports standard US QWERTY users.
  • Switches easily between Windows and Mac layouts via keyboard shortcut.
  • Wired USB-C connection only; no wireless options available.
  • Supports RGB lighting with south-facing LEDs for better keycap compatibility.

Typing Experience

  • Magnetic switches provide smooth, consistent keypresses without physical contact noise or bounce.
  • Adjustable actuation reduces accidental keypresses and allows faster input when desired.
  • Sound dampening layers and gasket mount reduce typing noise, making it suitable for quieter environments.
  • Cherry profile keycaps offer a familiar, ergonomic shape preferred by many typists.

Trade-offs

  • Wired-only connectivity limits use cases where wireless is preferred.
  • Advanced features like Dynamic Keystrokes and Analog Mode require software setup and some learning curve.
  • Magnetic switches are less common, so switch options are limited to compatible magnetic types.
  • 75% layout may lack dedicated function row or navigation cluster preferred by some users.
