Differences Between Sizes And Variants
The Sony INZONE KBD-H75 doesn't have any variants. You may see it referred to as the Sony KBD-G900 in some listings, or on some of Sony's support pages, but this appears to be an internal model reference. This is the label of the keyboard we tested.
Popular Keyboard Comparisons
The Sony INZONE KBD-H75 is the company's first foray into the high-end gaming keyboard market segment. It supports high-end specs that help it compete with the likes of the Wooting 80HE, the NuPhy Field75 HE, or the IQUNIX EZ80/EZ75. However, while this keyboard delivers outstanding latency performance in a very well-built package, its software is still relatively barebones, lacking many advanced features like SOCD and DKS that we have come to expect in this segment, and it's only officially compatible with switches included with the keyboard.
Compared to the competition, it's also on the more expensive side. The NuPhy Field75 HE is much cheaper, and even the Wooting 80HE in its plastic variant is less expensive. Both these keyboards offer the same outstanding performance, with much more robust software. While its performance is slightly less, the Lemokey P1 HE is as well-built and offers wireless connectivity for about half the cost. While the Sony keyboard doesn't have any major flaws, its pricing remains difficult to justify.

The Sony INZONE KBD-H75 and the Wooting 80HE both have outstanding performance and are very well-built. The Sony entry is a slightly smaller 75% compact layout, compared to the 80HE's unconventional compact TKL. The INZONE KBD-H75 is able to roughly match Wooting's outstanding latency performance, but its software isn't as polished or feature-rich. It lacks many advanced functions, such as Mod Tap and SOCD, that have become staples within the high-end gaming keyboard segment. The Wooting also comes with a four-year warranty and supports full analog input.
The Razer Huntsman V3 Pro and the Sony INZONE KBD-H75 are two very high-performance gaming keyboards with customizable actuation. However, while the Sony includes a hot-swappable design, the Razer doesn't. Both keyboards have outstanding latency performance, but the Sony keyboard has the edge with its 8000Hz polling rate and is slightly more responsive overall, even if the difference will likely be unnoticeable while gaming. The Sony keyboard is also quieter and delivers a slightly better typing experience. That said, only the Razer supports true analog input.
The NuPhy Field75 HE and the Sony INZONE KBD-H75 are two Hall effect keyboards with amazing latency performance that are suitable for even the most competitive gaming scenarios. They're both very well-built and have a similar compact 75% layouts. The NuPhy does distinguish itself with the inclusion of dedicated macro keys and a more polished and feature-rich configuration software. The Sony keyboard, on the other hand, has keycaps with shine-through legends that are easy to read in any lighting conditions, and it provides a much quieter typing experience.
The Lemokey P1 HE and the Sony INZONE KBD-H75 are two Hall effect keyboards with similar 75% layouts. The Lemokey has a solid aluminum case, while the Sony has an aluminum frame with a plastic bottom case. While the Lemokey distinguishes itself with an outstanding typing experience and the flexibility of wireless compatibility, Sony's wired-only keyboard delivers better latency performance and a higher 8000Hz polling rate.
Test Results
This keyboard uses a 75% layout that leaves out the numpad and a few navigation cluster keys you’d find on a full-size board. The compact design frees up extra desk space for mouse movement. Compared to other keyboards, such as the Wooting 80HE or the ASUS ROG Azoth, which are also partly made of metal, it's relatively lightweight. This can be a nice perk if you need to carry it around.
This keyboard combines a metal and plastic chassis, with an aluminum top casing and a plastic underside. The overall design is understated, in line with Sony's typical aesthetic. The build feels solid, showing almost no flex or twist thanks to the rigid aluminum frame and a metal backplate. There's a slight give when pressing down on the switches, a result of its gasket-mounted design. The keys do feel very dampened, adding a soft feel that may feel a tad mushy for some. The keycaps are double-shot PBT with a textured finish that resists fingerprints and oil buildup. The metal knob on the top-right also feels solid with a satisfying click and rotation. Stability is also excellent, thanks to sturdy rubber feet and incline stands that securely hold the board in place. A bit more weight would've provided a tad more stability, but it shouldn't be an issue nonetheless.
The overall assembly shows tight tolerances and careful attention to detail. The stabilizers and switches are pre-lubed and feel very stable. The key travel is very smooth and wobble-free across all keys. Larger keys are also quiet and free of rattle, and the space bar includes some foam to dampen the sound.
The Sony INZONE KBD-H75 offers acceptable ergonomics, though its height may cause some strain during long typing sessions. It lacks a wrist rest, so you'll need to angle your wrists slightly while using it. The two incline settings help adjust comfort, but the overall design may still feel a bit tall for extended use.
Sony doesn't indicate compatibility for aftermarket switches. During testing we confirmed that Gateron Dual-Rail KS-20, KS-20U, and Magnetic Jade switches are functionally compatible. However, while the software has a configuration feature, it doesn't properly adjust the actuation range to accommodate these other switches.
The Sony INZONE KBD-H75 features fully addressable per-key RGB lighting that you can customize through the software. It also supports a bunch of pre-made effects.
The shine-through legends are clear and easy to read, with almost no visual obstruction. The white-only lighting maintains a clean, pure tone that looks consistent across all keys, even if the bounce lighting has a slight blue-ish tint.
The included paracord-like cable is very flexible. Although it retains some kinks from packaging, it's pretty easy to straighten out.
This keyboard doesn't have any dedicated macro keys, but you can record up to 10 macros using the INZONE software.
The Sony INZONE KBD-H75 features a knob that you can customize to control OS volume or one of Sony's supported INZONE headsets. No other customization options are currently available for the knob.
Additionally, although this keyboard allows for creating Fn layer shortcuts through its software, it doesn't include any shortcuts by default, aside from the arrow Fn+Up/Down for adjusting backlight brightness.
This keyboard also includes an ultra-low latency mode that disables backlighting to minimize latency. You activate it by pressing the Esc key briefly while holding down the Fn key.
You can find a list of the supported shortcuts in the keyboard's manual.
Typing on this keyboard feels solid and consistent. The thick PBT keycaps feel sturdy with a light texturing that enhances grip and sound quality. The switches offer excellent stability with minimal wobble. However, the larger, stabilized keys, such as Enter and Backspace, feel slightly less smooth when bottoming out.
The board's tight gasket mount is dampened but still stiff, favoring quick gaming inputs over long typing sessions. Key travel feels bouncy and precise, with a 3.4 mm throw that closely resembles Gateron Magnetic Jade switches.
Sound feedback is muted and refined, though opinions may vary. Some users may find the dampened tone pleasant, while others notice a slightly inconsistent feel when fully bottoming out. Overall, it delivers a firm and stable typing experience, along with a satisfying sound profile.
This keyboard is quiet, thanks to several layers of acoustic material inside the case that effectively soften and round out the sound profile. The dampening keeps typing noise low, making it unlikely to disturb anyone nearby.
For this test, we used the default actuation point of 1.5 mm, and Rapid Trigger was turned off. You can fine-tune the actuation point anywhere between 0.1 mm and 3.4 mm, with increments as small as 0.1 mm. This keyboard produces smooth and accurate results that closely match the software settings.
The Sony INZONE KBD-H75 delivers excellent input precision, with a detection ratio that covers virtually the entire range of travel. The minimum step-depth is somewhat higher than some competing models, but it's low enough to find a suitable setting for your needs.
This keyboard doesn’t support true analog input, but that limitation has little impact on most games. It only matters for games like racing or flight simulation, where you would want to replicate gradual control inputs.
These are proprietary switches developed with Gateron. We noticed that they share design similarities with Gateron Dual-Rail KS-20U switches.
The Sony INZONE KBD-H75 has outstanding single-key latency performance. It delivers very responsive and consistent performance that's suitable for any type of game. We tested the keyboard using the following settings:
- Ultra Low Latency Mode ON
- Actuation point: 0.1 mm
- Rapid Trigger ON: press and release at 0.1 mm
Multi-key latency is exceptional, with extremely low and consistent performance, making this keyboard very well-suited for playing any game that requires additional keystrokes while multiple keys are pressed and maintained. We tested the keyboard using the following settings:
- Ultra Low Latency Mode ON
- Actuation point: 0.1 mm
- Rapid Trigger ON: press and release at 0.1 mm
The Sont INZONE KBD-H75 has very good chord split performance, with low 4-chord and 8-chord split delay. It's well-suited for playing games that require multiple simultaneous inputs, such as rhythm games.
The software comes in both a downloadable Windows version and a web-based option, each featuring a sleek interface that matches the keyboard's purple and black theme. Both versions include identical functionality, offering full driver control without any feature gaps. Within the allocation settings, you can create and assign macros, set keyboard shortcuts, and manage an additional Fn layer for quick access commands. Performance settings let you customize actuation and Rapid Trigger points, while lighting controls allow full per-key RGB customization, including brightness, color, and effect speed. Device settings add options to disable shortcuts or the Windows key, toggle ultra-low latency mode, and calibrate the board. The app sync feature lets you link specific profiles to switch on automatically when a chosen application starts. It's also possible to switch profiles by pressing the Tab key briefly while holding down the Fn key.
While it's relatively well laid out, the software feels barebones compared to what's offered by many competing manufacturers. It lacks many functions that have become staples in this segment, like SOCD, Mod Tap, or Dynamic Keystroke (DKS). The UI also isn't as polished when it comes to usability. For example, setting up Fn keys feels cumbersome, requiring multiple mouse presses to select a function, rather than the drag-and-drop interfaces that most manufacturers have adopted. Also, while it's possible to disable the Windows key lock on the software, there's no keyboard shortcut that allows you to do so.
