Cherry's Xtrfy K63W Pro changes how wireless gaming keyboards connect. It is the first to use low-energy ultrawide band (LE-UWB) instead of the crowded 2.4 GHz band. That means less interference and true 8,000 Hz polling in both wired and wireless modes.
LE-UWB replaces 2.4 GHz for interference-free 8K polling
Cherry acquired Xtrfy in 2022 and now releases the K63W Pro under the Cherry Xtrfy brand. The keyboard uses a 70% compact layout with a dedicated function row but no arrow keys. The compact layout targets gamers seeking a smaller footprint while retaining essential keys.
Specifications
- Polling rate: 8000 Hz (wired and wireless)
- Layout: 70% compact
- Switches: Cherry MX Low Profile 2.0 linear
- Switch lifespan: 100 million clicks
- Keycaps: ABS
The K63W Pro relies on Cherry MX Low Profile 2.0 linear switches rated for 100 million clicks. ABS keycaps sit on top. The keyboard includes per-key RGB lighting. Cherry says the LE-UWB connection delivers high speed and stays clear of interference.
6000 mAh battery delivers up to 1100 hours of use
The keyboard's battery life is a key highlight. A 6,000 mAh battery provides up to 1,100 hours of use, depending on the mode. That longevity comes from the low-energy design of the UWB radio. Charging is done via USB-C.
Pricing has not been announced. The K63W Pro goes on sale globally starting July 2. Regional availability and bundle options have not been announced.
The K63W Pro is not the first UWB peripheral. Gaming mice like the Elecom VM800 and Waizowl Cloud Ultra Nebula already use UWB. The keyboard applies LE-UWB technology to a new form factor emphasizing wireless 8K performance.
Cherry confirms the K63W Pro ships with true 8,000 Hz polling in both wired and wireless modes. The combination of LE-UWB connectivity and long battery life makes this keyboard a practical option for competitive gamers seeking low latency without wires.
