  • Dual-OS Smart Switch: Out-of-box Windows compatibility with two programmable blank layers. macOS users, shortcuts to replicate Mission Control/Launchpad, no third-party tools needed. Ideal for hybrid teams and cross-platform developers
  • Legend clarity meets vibrant RGB: Thick 1.5mm PBT keycaps resist oil and shine, while translucent doubleshot molding amplifies 16.8M-color RGB effects (8 preset modes + custom gradients). Perfect for low-light gaming setups and design studios
  • Pro-Grade TKL Layout for 20% More Desk Space: The J4’s Tenkeyless design removes the numpad while retaining arrow keys and F-row—30% smaller than full-size boards. CNC aluminum base ensures stability during intense gaming marathons.
