When it comes to mechanical keyboards, Cooler Master has carved a niche for itself, offering a compelling blend of functionality and affordability. Their latest offering, the MK770, takes aim at a broad audience, boasting features that cater to both gamers and everyday typists. I’ve spent the past few weeks putting this keyboard through its paces, and here’s a detailed breakdown of my experience.

The MK770 can be compared to the Cooler Master CK721, as both are wireless keyboard with a clean aesthetic. Both have their benefits and downsides, but in this article we will dive into the Coolermaster MK770.

Unboxing The MK770

Cooler Master keeps the packaging for the MK770 clean and straightforward. A sturdy cardboard box houses the keyboard itself, along with a detachable braided USB-C cable, a keycap puller, and a few spare keycaps. The included manual is concise and well-illustrated, guiding you through the setup process effortlessly. While the packaging isn’t flashy, it gets the job done, ensuring the keyboard arrives safely.


The first impression of the MK770 is undeniably striking. It boasts a 96% layout, ditching the numpad for a more compact and minimalist look. This translates to valuable desk space saved, particularly appealing for gamers and those with limited desk real estate. Construction-wise, the keyboard utilizes ABS plastic for the chassis, which feels sturdy enough for everyday use. However, the keycaps are the real stars here – crafted from PBT plastic, they offer a delightful textured surface that resists wear and tear, a common concern with ABS keycaps.

Diving Deeper

Beyond the aesthetics, the MK770 boasts an impressive array of features. One of the highlights is the inclusion of hot-swappable Kailh Box V2 switches. This is a fantastic feature for tinkerers and enthusiasts alike. It allows users to customize their typing experience with a wide variety of switch options, from clicky and tactile to linear and quiet. If you’re a gamer who prefers the crisp feedback of a clicky switch, you can easily swap them in.

Or, if you’re a writer who prioritizes silent keystrokes to avoid disturbing those around you, there are plenty of linear options available. This level of customization caters to individual preferences and allows users to experiment and find their perfect match. The keyboard comes pre-installed with the tactile Kailh Box V2 Brown switches, which offer a satisfying bump and moderate sound profile – a good middle ground for those who aren’t sure where to start.

Another noteworthy aspect is the MK770’s connectivity options. It offers a trifecta of choices – wired USB-C, Bluetooth 5.1, and 2.4 GHz wireless. The wired connection ensures the lowest latency for competitive gaming, where every millisecond counts. Bluetooth provides a convenient option for connecting to laptops or tablets on the go, eliminating the need for tangled wires. The 2.4 GHz wireless strikes a balance, offering a reliable connection with minimal latency for most gaming scenarios, making it a versatile choice for users who don’t want to be tethered by a cable.

Cooler Master complements the feature set with a per-key RGB lighting system. The keyboard illuminates beautifully, with each key sporting its own LED. The included software allows for extensive customization. You can choose from a variety of presets like wave patterns or reactive lighting, or create your own custom lighting effects to match your setup’s theme or your personal preference. Whether you prefer a subtle glow or a vibrant explosion of colour, the MK770 can accommodate your taste.


The Cooler Master MasterPlus+ software allows for customization of the MK770’s RGB lighting and macro creation. While the software offers a decent level of functionality, it’s not without its quirks. The interface can feel a little cluttered at times, with menus nested within menus. I also encountered a few minor bugs during the testing period, such as occasional crashes or unresponsive buttons. Hopefully, Cooler Master will continue to refine the software and iron out these wrinkles in future updates. A more intuitive and stable software experience would elevate the overall package.


The Cooler Master MK770 is a compelling option for gamers and typists alike. Its hot-swappable switches provide unparalleled customization, allowing you to tailor the keyboard to your specific needs. The compact tenkeyless layout saves space on your desk, while the multiple connectivity options offer flexibility for various use cases. The build quality is solid, the PBT keycaps are a welcome touch for their durability and pleasant texture, and the per-key RGB lighting adds a touch of flair.

However, the software could benefit from further refinement to improve user experience. While it allows for customization, a more streamlined interface and better stability would be welcome improvements. Currently, the MK770 is unavailable in the UK, however this may change if the demand for such keyboard arises.

Overall, the Cooler Master MK770 is a feature-packed mechanical keyboard that we at Battlerigs definitely recommend!
