Keychron K4 HE Review
Bottom Line
Choose the K4 HE for fast Hall Effect gaming, strong build, and flexible wireless use. Skip it if you dislike cramped 96% layouts, dimmer Special Edition lighting, or wired-only software changes.
Best for
Gamers who want Hall Effect speed features without moving to far pricier boards, and users who still want a numpad, wireless flexibility, and broad OS support.
Not for
People who dislike condensed 96% layouts, want brighter shine-through lighting, or want full freedom to use non-Gateron magnetic switches and change settings wirelessly.
Verdict
The Keychron K4 HE stands out because it brings rapid trigger, adjustable actuation, analog-style input, and robust web customization to a well-built 96% board at a price reviewers repeatedly call reasonable. It also works across multiple operating systems and connection modes, and most reviewers liked its sound and overall typing experience. The tradeoff is that the condensed layout is divisive, switch compatibility is limited, and software changes usually require a wired connection. Special Edition lighting and backlight brightness also draw mixed feedback. Even so, the review set consistently treats it as one of the better-value Hall Effect keyboards for people who want one board for gaming and work.
