Overview

The Razer BlackWidow V4 Pro Wireless is a 75% layout gaming keyboard that pushes wireless performance into territory previously reserved for wired boards. Its headline feature is true 4K Hz wireless polling via Razer HyperSpeed and HyperPolling technology, reporting inputs 4,000 times per second to deliver a responsiveness advantage that competitive gamers will appreciate. Beyond the wireless dongle connection, Bluetooth 5.1 support lets you pair and switch between up to three additional devices, making the keyboard practical for multi-device setups that span gaming PCs, work laptops, and tablets.

Under the keycaps, the BlackWidow V4 Pro is built for customization and acoustic quality. The socketed PCB accepts both 3-pin and 5-pin mechanical switches, so you can hot-swap the pre-installed Orange Tactile switches for any compatible alternative without soldering. Razer has invested in the typing experience with a gasket-mounted FR4 plate, tape-modded PCB, factory-lubricated screw-in stabilizers, and dual layers of sound-dampening foam — refinements that produce a clean, satisfying keystroke. The integrated OLED display shows system metrics or custom GIFs, and the Command Dial offers up to 100 programmable modes for quick adjustments. Per-key Razer Chroma RGB lighting and a striking two-sided underglow complete the package, with game integration support for hundreds of titles. A magnetic plush leatherette wrist rest is included for comfort during extended sessions.
