Unboxing

The KiiBOOM Breeze 75 comes in a well-designed color box with a clean and modern aesthetic. The front showcases a simple outline of the keyboard, accompanied by the brand logo and model name, while the back keeps things minimal with just a support email and website link. The packaging itself is solid, featuring a thick outer shell and internal foam padding to keep everything secure during shipping. Every component is neatly arranged inside, ensuring the keyboard arrives in perfect condition.

Inside the box, the keyboard is nestled in a protective foam insert, along with a microfiber cloth, a user manual, and a 2-meter braided USB-C to USB-A cable. A USB adapter for 2.4 GHz wireless mode is also included, making it easy to switch between wired and wireless setups. The package also contains keycap and switch pullers, a small screwdriver, and two spare switches, providing everything needed for customization and maintenance right out of the box.

Design

The KiiBOOM Breeze 75 features a 75% layout with 81 keys, offering a compact form while keeping all the necessary directional and function keys intact. This layout is similar to what you’d find on a laptop keyboard but with more functionality and better ergonomics. The design of the Breeze 75 is one of its highlights, with a blend of aluminum and acrylic giving it a sleek look that doesn’t compromise on performance. We tested the Green model, which comes with a striking two-tone combination of green and white keycaps.

The layout is similar to a laptop keyboard but offers more functionality. A metal knob in the upper right corner allows for easy control of RGB lighting or volume. Measuring 325 x 140 x 45 mm, it has a compact yet stylish design that fits well on any desk. The build quality stands out in its price range, featuring a CNC-machined aluminum top panel for durability and a transparent acrylic body for a sleek, modern look. Rounded edges enhance its refined appearance, while the aluminum backplate doubles as a battery compartment. Weighing 1.5 kg, it feels solid and stable without being too heavy.

The KiiBOOM Breeze 75 keyboard features a mix of acrylic and aluminum on the back, creating a sleek and modern appearance. The acrylic section reveals the internal PCB, while a large KiiBOOM logo sits on the right side. The attention to detail in the assembly leaves no space for imperfections, with every component neatly arranged. The battery compartment is integrated smoothly into the design, maintaining a clean look. Four rubber pads provide a firm grip on surfaces, keeping the keyboard stable during use.

The keyboard’s controls are positioned on the back, where you’ll find a USB-C port for a wired connection, a toggle for switching between Windows and macOS, and another switch to change between 2.4 GHz wireless, USB, and Bluetooth modes.

The Breeze 75 employs a gasket mount system designed to enhance typing dynamics and sound isolation. The silicone ring wraps around the PCB and plate, providing a secure yet flexible connection to the case. This system, supported by a silicone foot resting at the bottom, offers a slight bounce that maintains firmness without feeling mushy. The keyboard integrates sound-dampening materials, including Poron foam beneath the plate and XPE foam under the switches, which collectively absorb vibrations and reduce hollowness. This attention to acoustic detail contributes to a more satisfying and immersive typing experience.

The use of a polycarbonate (PC) plate paired with a 1.6mm PCB ensures a blend of flexibility and sturdiness in each keystroke. The PC plate adds a subtle softness to the key presses, while the thicker PCB maintains durability. These components work together to create a balanced sound profile, with a gentle, subdued acoustic that appeals to enthusiasts seeking a refined auditory experience. Whether typing or gaming, the Breeze 75 delivers precise feedback and a consistent feel, making it a versatile choice for various applications.

Keycaps & RGB LEDs

The Breeze 75 keyboard comes with cherry-colored Sub-PBT keycaps that complement the aluminum faceplate while allowing the acrylic backlight to shine through. The illuminated acrylic edges blend naturally with the PBT keycaps and aluminum front panel, creating a cohesive design. PBT plastic is known for its durability, resistance to wear over time, and avoiding the glossy shine that develops on ABS keycaps.

The keyboard uses the Cherry profile, which is a popular choice for both gaming and typing due to its comfortable height and shape. The keycaps have solid legends that do not allow light to pass through, maintaining a clean and uniform look. The ergonomic design reduces strain during long typing sessions, making it a reliable option for everyday use. Whether for casual typing or competitive gaming, the layout provides a balanced and responsive experience.

With 22 RGB modes and six additional backlight effects, the Breeze 75 offers plenty of customization options to suit different preferences. The LEDs are positioned on the south side, ensuring even lighting across the keycaps. The acrylic base enhances the overall look with subtle edge lighting, creating an ambient glow that adds to the keyboard’s character. Users who enjoy RGB effects will find the customization options both practical and visually appealing.

KiiBOOM Matcha Latte V2 Switches

The KiiBOOM Breeze 75 comes fitted with Matcha Latte V2 switches, which offer a choice between 38g or 45g actuation forces depending on the color. The unit tested here features the 45g variant, providing a linear feel that works well for both typing and gaming. These switches use a self-lubricating LY stem, a hybrid material known for its exceptionally low friction. With a coefficient of friction as low as 0.02—far lower than the 0.3 typically found in POM-based switches—the result is an ultra-smooth keystroke that feels effortless and consistent.

Beyond smooth operation, these switches are designed with durability in mind. The five-pin design ensures a stable connection with the PCB, while the polycarbonate top and bottom housing contribute to a crisp sound profile. With a total travel distance of 3.8mm and a pre-travel of 2.0mm, each press feels precise without being too abrupt. Rated for 50 million keystrokes, they are built to withstand years of heavy use, whether for work or gaming.

For those who enjoy RGB lighting, the Matcha Latte V2 switches come with built-in light diffusers that enhance brightness and color vibrancy. The diffusers help distribute light evenly across the keycaps, making the backlighting appear richer and more uniform. Whether playing games in a dimly lit room or simply appreciating the keyboard’s design, these switches contribute to a visually striking experience.

KiiBoom Custom Driver

The Kiiboom Breeze 75’s software provides a comprehensive set of customization options, allowing users to tailor the keyboard to their specific needs. Key remapping is straightforward, enabling easy reassignment of functions without any unnecessary steps. The RGB lighting can be adjusted with a variety of effects, colors, and brightness levels, making it simple to match different setups or moods. The interface is clean and well-organized, ensuring that even those unfamiliar with customization software can navigate it without confusion. Cloud storage integration is a valuable addition, allowing users to save multiple profiles and sync them across different devices without manually transferring settings. This feature is particularly useful for those who switch between multiple Kiiboom keyboards or use different setups for work and gaming.

The software’s macro recording function captures both keystrokes and mouse clicks, making it a versatile tool for both gaming and productivity tasks. Users can create complex input sequences, automating repetitive actions for increased efficiency. However, the software supports only a single function layer, which may feel restrictive for users who rely on multiple layers for advanced macros or shortcuts. Despite this, the existing customization options are well-implemented and provide enough flexibility for most users. The combination of intuitive design, practical features, and cloud support makes the Kiiboom Breeze 75’s software a strong companion for those who want deeper control over their keyboard’s functionality.

Connectivity

The Breeze 75 offers flexible connectivity with Bluetooth 5.0, 2.4GHz wireless, and a wired option, making it easy to switch between different devices. Whether using a Bluetooth-enabled laptop, a desktop with a USB port, or a tablet with a Type-C connection, the keyboard ensures seamless compatibility across various setups.

Wired Mode

The KiiBOOM Breeze 75 includes a Type-C cable along with its wireless receiver, providing a simple way to switch to a wired connection. Plugging in the cable and setting the toggle switch to the center position activates the wired mode, ensuring a stable connection while also keeping the keyboard charged. This allows uninterrupted use, even if the battery runs low during wireless operation.

Pairing Wireless 2.4Ghz

Switching to wireless mode is straightforward. Slide the switch to the 2.4G position to enable the connection, then press and hold Fn+4 for a few seconds until the indicator starts flashing rapidly. This signals that the keyboard is ready to pair. Once the connection is established, the indicator remains steady, confirming that the setup is complete.

Pairing Bluetooth

Switching to Bluetooth mode is simple. Slide the toggle to the BT position, then hold Fn+1/2/3 for a few seconds until the indicator starts flashing rapidly. This means the keyboard is ready to pair. On your device, enable Bluetooth, find “KIIBOOM Breeze 75” in the list, and connect. Once paired, the flashing stops, confirming the connection. You can switch between three paired devices by pressing Fn+1/2/3.

Battery

The Breeze 75 runs on dual 4000mAh batteries, providing a total capacity of 8000mAh. This ensures extended use without frequent recharging, making it a dependable option for both casual and intensive users. For those looking to maximize battery life, turning off the backlight significantly reduces power consumption. With the lighting disabled, the keyboard can last up to a week, making it a practical choice for users who value efficiency over aesthetics. Whether for work or gaming, the keyboard adapts to different needs by balancing battery life and performance.

Checking the battery level is straightforward with the built-in indicator system. When the battery is low, the Left Ctrl key blinks red, while the charging status is displayed with a solid red light. Once fully charged, the key lights up alongside the backlight. Users can also check the exact battery percentage by holding Fn + Backspace—keys from 1 to 0 illuminate to represent charge levels. For example, if keys 1 through 6 light up, the battery is at 60%, while all ten keys lit indicate a full charge.

Use Experience

Typing Experience

After a full week of daily use, the KiiBOOM Breeze 75 has proven to be both comfortable and responsive. The gasket mount design, combined with the Matcha Latte V2 switches, delivers a soft yet firm typing experience that remains consistent over extended sessions. The 45g actuation force strikes a good balance between speed and control, making it well-suited for both writing and gaming. The linear feel is smooth, and there’s no scratchiness, even when rapidly typing for long periods. The keycaps, with their Cherry profile and textured PBT material, provide a pleasant tactile surface that resists oil buildup, keeping the keyboard looking and feeling fresh.

Sound and Acoustics

The sound profile of the Breeze 75 leans toward a dampened, muted tone rather than an overly loud or high-pitched clack. The combination of a polycarbonate plate, Poron foam, and XPE padding effectively minimizes hollowness and vibrations. Bottoming out produces a deep, cushioned thock rather than a sharp snap, which makes long typing sessions less fatiguing to the ears. The stabilizers come pre-lubed, and while they perform well out of the box, some users might prefer additional fine-tuning for an even smoother sound. The metal knob adds a tactile click when adjusting volume or RGB settings, complementing the keyboard’s refined acoustic profile.

Day-to-Day Usability

Using the Breeze 75 across different tasks, from casual browsing to productivity work, has been a smooth experience. The wireless modes, including Bluetooth and 2.4 GHz, maintain stable connections without noticeable latency. Switching between macOS and Windows is seamless with the dedicated toggle, and all essential shortcuts work as expected. The ergonomic angle and overall weight provide a stable feel, preventing unwanted movement on the desk. The RGB lighting remains vivid even in well-lit environments, and the edge glow from the acrylic housing adds a subtle visual flair without being distracting. Whether used for work or gaming, the Breeze 75 holds up as a reliable and stylish daily driver.
