Keychron J4
Wireless TKL
- Tri-mode connectivity (2.4 GHz, Bluetooth 5.2, wired) for flexible device switching.
- TKL (80%) layout retains function row and navigation cluster.
- Includes multiple layers of acoustic foam (IXPE, PET, EPDM) for sound dampening.
- Battery-dependent for wireless use, with a listed capacity of only 1mAh (likely a placeholder, indicating potential battery life uncertainty).
- Larger TKL footprint is less portable than a 60% board.
- No barebones kit option is mentioned, limiting initial build flexibility.

Keychron V4
Wired 60% Custom Keyboard
- Highly customizable with a barebone kit option available.
- Features screw-in PCB stabilizers for improved stability and modding potential.
- South-facing RGB LEDs prevent interference with Cherry and OEM profile keycaps.
- Wired-only connectivity, lacking wireless options.
- 60% layout requires using layers for arrow keys, function row, and navigation, which has a learning curve.
- Case material is listed as ABS plastic, which may feel less premium than metal alternatives.
Your primary need dictates the choice. If wireless operation and a full TKL layout are non-negotiable for your desk setup and workflow, the Keychron J4 is the appropriate tool. If you prioritize a compact, wired keyboard as a foundation for deep customization and modding, the Keychron V4 offers exceptional value and flexibility in its price tier.

Keychron J4 vs V4: your questions
Yes, the Keychron J4 is designed for wireless gaming. According to its product page, it features a 2.4 GHz wireless connection with a 1000 Hz polling rate, which the manufacturer states provides low latency suitable for competitive games.
Yes, the Keychron V4 has Mac support. The vendor description specifies it includes an additional set of keycaps for macOS and features a system toggle to switch between macOS and Windows layouts, allowing you to save a separate layout for each OS.
Both aim for a good typing experience but through different means. The J4 uses multiple acoustic foams (IXPE, PET, EPDM) and adjustable angles for sound and comfort. The V4 uses a silicone acoustic pad, screw-in stabilizers, and pre-lubed K Pro switches for a smooth, stable feel. Preference depends on sound profile and layout.
No, the Keychron V4 does not have Bluetooth. The specifications list its connectivity as wired only, using a Type-C cable. It does not offer any wireless connectivity options.
The Keychron J4 offers keycap options. According to the vendor, it provides a choice between Cherry profile shine-through keycaps and MDA profile non-shine-through keycaps, allowing you to select based on your preference for backlight visibility.
The fully assembled Keychron V4 comes with Keychron K Pro switches, which are factory pre-lubed (excluding clicky variants). The barebones kit does not include any switches, allowing you to install your own compatible 3-pin or 5-pin MX-style switches.
Yes, both keyboards support advanced key remapping. They are compatible with the open-source QMK firmware and the Keychron Launcher web app, allowing for extensive customization of keys, layers, and macros.
The Keychron V4 is more portable due to its smaller 60% layout, measuring 304mm x 117mm. The Keychron J4 has a larger TKL (80%) footprint. Furthermore, the V4 is wired-only, so you don't need to worry about battery life while traveling.
Yes, both keyboards support 5-pin switches. The product descriptions for both the J4 and V4 state their hot-swappable sockets support both 3-pin and 5-pin MX-style mechanical switches.
The J4 has north-facing LEDs, while the V4 has south-facing LEDs. South-facing placement, as on the V4, prevents interference with the keycaps on Cherry and OEM profiles, a common issue with north-facing LEDs. However, north-facing LEDs can provide brighter shine-through effects with the right keycaps.
Yes, the Keychron V4 offers extensive ISO layout support. The vendor lists ISO, JIS, ANSI, and ISO-DE layout standards, and specifically mentions ISO collections for UK, German, Nordic, Swiss, French, and Spanish layouts.
According to the vendor description, the V4 barebones kit includes the ABS plastic housing, the keyboard PCB with hot-swappable sockets, screw-in stabilizers, and the steel plate. It does not include keycaps or switches.
