GET ATTACHED – BUT ONLY IF YOU WANT TO

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.

*Lever to remove the top plate is located underneath the dongle cover. Pull the lever towards the front of the keyboard to loosen the top plate for removal. If you accidentally press the lever or decide not to remove it, place your thumbs on the left and right side of the keyboard top plate and gently rock it side to side to lock it back into place.

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.

*To ensure optimal use of the product, please download the MasterPlus+ software and update the latest firmware.

*In wired mode, you cannot update the firmware associated with wireless functionality. In order to fully update, please be sure to plug the dongle into your PC and make sure the CK721 is successfully connected via 2.4GHz. Start up the MasterPlus+ software and proceed through the prompts in order to fully update your keyboard to the newest functions.

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.

RGB PER-KEY BACKLIGHTING

No-nonsense backlighting for a no-nonsense keyboard - illuminate your keys based on control schemes, or just do it because it looks cool with 16.7 million colors to mix and match.

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.
