The Phantom 81 boasts a fully transparent acrylic case, allowing full visibility of the switches and keycaps, making it stand out from the competition.

KiiBOOM, the brand behind the Phantom 81, has taken the design to the next level by incorporating gold accents on the plate, knob, rear weight, and wireless connectivity plate. This unique aesthetic creates a harmonious balance between the clear acrylic case and the gold accents, making it one of the best-looking keyboards in its class.

Not only is the Phantom 81 visually stunning, but it is also built to last, with its top and bottom case made of thick, heavy material. This keyboard is durable and has a premium feel to it, measuring 0.83 inches in the front and 1.42 inches in the back and weighing over 3.25 pounds. KiiBOOM has not cut any corners with the Phantom 81, using metal for the knob, rear weight, and connectivity plate, ensuring that this keyboard is beautiful and built to last.


At the heart of this keyboard are the KiiBOOM Crystals, medium-weight switches with an actuation force of 55 grams. These switches come pre-lubed, ensuring smooth and satisfying key presses with every use. The shorter travel distance of 3.6mm and 1.6mm of pre-travel for actuation make it a great choice for fast-paced gaming.

In addition to the switches, the Phantom 81 also features tall. SA-style keycaps made of thick polycarbonate plastic. These keycaps provide a premium look and feel and maintain their glassy appearance over time. The legends are bold and center-printed, adding to the overall aesthetic of the keyboard.

But that’s not all – the Phantom 81 also boasts crystal-clear switches. Which allows RGB lighting to shine through from every angle. This makes it the perfect keyboard for those who want to add a touch of customization to their setup.

With its hot-swap sockets, the Phantom 81 allows easy switch replacement without the need for soldering. The PCB also supports 5-pin switches, ensuring compatibility with high-end switch options.

But KiiBOOM doesn’t stop there; they have incorporated a gasket-mounted design for the Phantom 81. This design uses silicone tabs to isolate vibrations and reverberation from typing, resulting in a quieter and softer typing experience. Experience the premium feel of a custom keyboard without breaking the bank with the Phantom 81 by KiiBOOM.

Combined Plate

This keyboard boasts a unique design that features a sheet of the combined plate and switches silicone. Which not only adds to the overall aesthetic but also provides a softer typing experience with dampened keystrokes. Our sample was silicone, which is still suitable for this design.

Custom keyboard enthusiasts will also be pleased to know that the Phantom 81 has a few hidden treats in store. The keyboard comes equipped with screw-in stabilizers, which are popular among enthusiasts for their added stability. The south-facing switches offer wider compatibility for third-party stabilizers and keycap sets. Whether you’re looking to swap out for something more custom in either area. The Phantom 81 has you covered. It should support it with no problem, though it’s worth noting that we did not test other stabilizers. So plate tolerances may still come into play for stabilizers.

Kiiboom Software

The Phantom 81 is designed to be user-friendly, making it easy to set up and use right out of the box. However, for those who want to take their gaming experience to the next level, the KiiBOOM software is available for download. This powerful software suite gives you access to macro control, key sensitivity tweaks, and lighting customization. Allowing you to customize your keyboard to suit your gaming needs fully.

Performance and Experience

The KiiBOOM Phantom 81 mechanical keyboard is a top-notch option for those searching for a visually stunning and high-performing keyboard. The keyboard boasts a sleek and attractive design that is sure to catch the eye of anyone who lays their gaze upon it. The case is constructed with precision and attention to detail, making it an ideal choice for those looking to add a touch of elegance to their workspace.

Not only does the KiiBOOM Phantom 81 look great, but it also feels and sounds amazing to type on. The smooth switches provide a comfortable typing experience and are easy to get accustomed to. The typing angle is perfect for those who prefer to type without a wrist rest, and the switches are light and effortless to press, making them less prone to typos.

Additionally, the stabilizers come pre-lubed and tight, eliminating the need for additional lube and ensuring that the keyboard is ready to use straight out of the box. Overall, the KiiBOOM Phantom 81 is an exceptional choice for anyone searching for a high-performing, visually stunning keyboard.

KiiBOOM has excelled in optimizing the sound of its keyboard through the use of silicone pads under the plate and switches, as well as dampening gaskets around the edges. This results in a deeper and more satisfying typing experience compared to other keyboards that use polycarbonate keycaps.


Although the keyboard is gasket-mounted, the typing experience is not as soft as expected. A slight flex is observed when pressing down on the keys, but it does not affect the actual typing experience. The gaskets effectively isolate typing sounds from the rest of the case, eliminating sharpness and adding a touch of softness to the overall experience.

The wireless connectivity of the keyboard is impressive, as it goes into sleep mode after a few minutes of inactivity to preserve battery life. Waking up the keyboard is quick and seamless, with typing resumed within a few seconds.

The software for the keyboard may be its biggest drawback. As it is limited in terms of lighting and key customization options compared to those offered by other gaming keyboards software such as Razer, Logitech, and Corsair. However, considering the company’s size and age. The availability of any customization options is still appreciated. Including VIA support would have been preferable, but the current options are still functional. The KiiBOOM keyboard offers a solid typing experience with excellent sound optimization and wireless connectivity.


The KiiBOOM Phantom 81 is a revolutionary mechanical keyboard that marks the brand’s debut in the industry. Its unique transparency, durable construction, and advanced features, such as PCB-fixed stabilizers and gasket type mounting system, make it a top-of-the-line option for custom keyboard enthusiasts.

Additionally, the transparency is expertly executed, providing optimal readability with the LEDs on and off. While the US ANSI layout, a common issue with Chinese keyboards, is present. The Phantom 81 more than justifies its price point compared to other high-end options in the market. We hope that this is the beginning for KiiBOOM and that they continue to release exceptional products like the Phantom 81.

The KiiBOOM Phantom 81 is a top-of-the-line option for any end buyer in the market for a new keyboard. Overall, I highly recommend the Phantom 81 Mechanical Keyboard for anyone in need of a high-performance keyboard with a stylish design.
