The CK721 wireless mechanical keyboard is an elegant small form factor solution for both work and play. A 65% layout and hybrid wireless technology emphasizes portability with nearly universal OS & platform compatibility, while a sandblasted aluminum body imbues the sleek durability necessary in an everyday workhorse. In addition, mechanical switches give you the reliable performance, feel, and responsiveness you can count on. With all the features you need that just work, the CK721 is your go-to keyboard you want in the office and your gaming setup.

Reliable Mechanical Switches
Dominate in any type of game with mechanical switches good for 50 million keystrokes. All the responsiveness, accuracy, and tactile satisfaction you can handle. Available in red (linear), brown (tactile) and blue (clicky).

GET ATTACHED � BUT ONLY IF YOU WANT TO
Choose between wired Type-C connectivity or two types of wireless: 2.4 GHz for minimal latency or Bluetooth 5.1 for superior convenience with three simultaneously connected devices, no matter if it�s your laptop, mobile, tablet or PC. Who says you can�t have your cake and eat it too?

UNIVERSAL COMPATIBILITY FOR WORRY-FREE USE
It doesn�t matter which side of the computer spectrum you fall on; the CK721 is virtually compatible with every modern device on the planet. That includes devices with: Windows 8 and above, Mac OS X, iOS and Android. And for maximum convenience, easily soft-switch between all devices with a simple keypress.

PORTABLE 65% LAYOUT & SOFT WRIST REST
Low-friction cloth to keep you comfortable during long gaming sessions along with a compact layout and design, perfect for on-the-go use with mobile devices and laptops.

RUGGED, DURABLE DESIGN AND REMOVABLE TOP PLATE
The CK721 is built to last, with a thoughtful design that�s equal parts minimalistic and rugged, with an aluminum top plate that is easily removable for customization or easy access for maintenance.

TAKE CONTROL WITH A PRECISION DIAL
Better known as �rotary encoders� in nerdier circles, a three-way precision dial enables you to adjust volume, cycle through color modes, and more � all customizable via our MasterPlus+ software.

Masterplus+ Suite Support
The CK721 is one of the first Cooler Master products to support the new MasterPlus+ software, a unified control hub where managing all of your Cooler Master gear is easier than ever. Adjust all of your settings from one dashboard, and even sync your lighting settings across multiple devices with ease.

REAL-TIME ADJUSTMENT OF SETTINGS
When you�re in a groove, the last thing you want to do is Alt+Tab out to adjust your keyboard settings. The CK721 combats that with an innovative On-the-fly System. In the heat of battle, easily adjust per-key backlighting, switch lighting modes, and even record macros with just a few keypresses. Get the functionality of software without needing to have software bloating your system - saving you time and precious PC resources.

TWO-STEP KICKSTAND FOR IMPROVED ERGONOMICS
Adjustable feet improves the ergonomics of the CK721 by letting you control the angle of the keys to reduce wrist strain.

ENHANCE YOUR BOARD WITH ACCESSORIES
Coming soon we'll have a braided coiled cable, PBT keycap sets and colored aluminum top plates for you to customize and truly make the CK721 yours.
