## Long description

Keychron K1X-B4 is an 80% mechanical keyboard with 87 keys in a compact, straight TKL-like form factor. It offers dual connectivity via USB and Bluetooth, a QWERTY English layout and RGB LED backlighting in a grey finish. The design combines low-profile mechanical switching, QMK-compatible firmware and audible damping elements to provide a balance of responsive typing, wireless convenience and customizable lighting for both productivity and gaming use.
Advantages
The keyboard supports both wired USB and Bluetooth connections, allowing seamless switching between desktop and mobile devices. Low-profile mechanical switches deliver tactile feedback with a reduced overall height compared with standard mechanical boards. QMK firmware and the Keychron Launcher web configurator enable key remapping, macro creation and profile management without installing native software. Enhanced acoustic foams reduce key noise and improve typing comfort, while RGB backlight and shine-through keycaps provide clear visual feedback and adjustable lighting effects.
Suitable for
 Office typing and content creation
 Casual and competitive gaming with low latency in wired mode
 Mobile and multi-device workflows via Bluetooth
 Users who require key remapping and macro programming
 Environments where a compact 80% layout saves desk space
Key specifications

 Connectivity: USB (wired) and Bluetooth (wireless)
 Layout: QWERTY English
 Backlight: RGB LED with multiple dynamic modes and adjustable hue/brightness

How to use
Connect the keyboard to a computer with the included USB cable for wired operation and access to the highest polling rate. For wireless use, pair the device over Bluetooth to one of up to three supported devices and switch between them using the device-selection keys. Use the Keychron Launcher web app to remap keys, create macros or switch profiles online without installing software; open the web configurator in a browser and follow on-screen instructions. Adjust RGB lighting and typing angle physically or via available function-key commands as described in the user manual.
Usage recommendations
For the quietest experience, use the version with acoustic foams installed and choose switches with lighter actuation. When gaming competitively, prefer wired USB mode to minimize latency. Back up custom keymaps in the Keychron Launcher and test macros after programming to ensure expected behavior across both macOS and Windows layouts.
