Cooler Master Keyboards at 2023 CES: MasterKeys MK770 and CK721 in New Colors

Cooler Master introduced several new color schemes of its MasterKeys MK770 and CK721 mechanical gaming keyboards at the 2023 International CES. The MK770 has a unique 99-key layout that retains the Numpad, squeezes the arrow keys between the main QWERTY key-cluster and the Numpad, and relocates the insert/delete/home/end/page-up/page-down cluster. This is essentially a full-size keyboard, but only 38 cm in length (comparable to some TKL keyboards). The MK770 supports three kinds of connectivity—USB (including type-C), wireless over Bluetooth 5.1, or wireless over a low-latency proprietary 2.4 GHz RF.

The MK770 comes with hot-swappable Kailh Box V2 mechanical switches, a gasket mounted construction, PBT doubleshot keycaps with four distinct colors per color-set; and pre-lubed stabilizers for the keycaps. You get individual-key RGB lighting, a multi-function customizable wheel, and a 4000 mAh battery (the company didn’t mention battery life on a full charge). In the USB and 2.4 GHz RF mode, the keyboard offers a 1000 Hz interface polling-rate, which drops down to 125 Hz in Bluetooth mode. A 512 KB onboard memory stores lighting and macro data. The four color sets the MK770 are offered in are: cyan+magenta+gray; mint-green+forest green+off-white; an Attack on Titan theme; and Fruity Pebbles theme. The CK721 Sakura Limited Edition is a 65% format mechanical gaming keyboard that uses TTC mechanical switches, PBT doubleshot keycaps, a 3-way digital dial, RGB lighting for each key, and triple interface just like MK770 (USB, Bluetooth, and 2.4 GHz RF). A 2,000 mAh battery provides up to 73 hours of use without lighting.
