INTRODUCTION
Few peripherals impact the day-to-day computing experience as much as a keyboard. While processing power and display technology often grab the headlines, the device sitting beneath our fingertips ultimately defines how we interact with our systems. The keyboard market has expanded dramatically over the last decade, introducing a wide variety of form factors and technologies. Users can now choose between membrane and mechanical switches, wired or wireless connectivity, compact or full-size layouts, and a growing list of premium features designed to improve comfort, responsiveness, and typing acoustics. Among the most popular layouts is the TKL format, which removes the numeric keypad to create a more compact footprint without sacrificing essential functionality. Τhe IQUNIX EC75 Shadowblade aims to deliver exactly that balance while adding its own take on modern mechanical keyboard design.
Founded in 2014, IQUNIX merges aesthetics with technology to create timeless desktop tech products. The brand aims to create desktop tech products that provide aesthetic pleasure and embody timeless design for users. Known for the award-winning ZX-1 ITX PC case, IQUNIX gained further acclaim in 2022 with a limited-edition keyboard collaboration with The Little Prince. Currently, IQUNIX offers high-quality, visually stunning keyboards and peripherals, continuously pushing the boundaries of design to meet users' functional and aesthetic needs.
The IQUNIX EC75 Shadowblade is a premium 75% Hall Effect gaming keyboard built around the company's custom Diamond Pro adjustable magnetic switches, combining competitive gaming performance with a refined everyday typing experience. Featuring Hall Effect sensing technology, the EC75 supports adjustable actuation, Rapid Trigger sensitivity down to 0.01 mm, SOCD, DKS, Mod Tap, and other advanced key behaviors through IQUNIX's web-based HyperCore V3 software platform. Performance-focused specifications include an 8000Hz polling rate, 8000Hz scan rate, and a quoted latency of just 0.125ms, allowing the keyboard to accurately track and respond to even the slightest key movements. The factory pre-lubed (self-lubricating) Diamond Pro switches offer a 3.3 ± 0.4 mm total travel, customizable actuation, and a lifespan rated for up to 100 million keystrokes. Construction combines a CNC-machined aluminum top frame with a lightweight PC bottom case, while a gasket-mounted design, PET layer, internal damping materials, and durable PBT keycaps are employed to enhance typing feel and acoustics. Additional features include per-key RGB customization (19 lightning effects), three-stage adjustable feet providing 2.8°, 6°, and 10° typing angles, onboard profile support, and extensive browser-based (HyperCore V3 platform) tuning options, making the EC75 equally suitable for esports-focused gamers and users seeking a premium daily-driver keyboard.
SPECIFICATIONS AND FEATURES
PACKAGING AND CONTENTS
A large product drawing along with the company logo and the keyboard size are all placed at the front of the box.
The keyboard type, name, electrical requirements, bundle contents, company information and country of manufacture are printed at the rear.
The fact that the EC75 comes with a clear plastic cover is a great start.
Inside the box you’ll find the EC75 Hall Effect Mechanical Keyboard, keycap puller, cleaning brush, detachable USB-C to USB-A cable, warranty card and the user manual.
THE EC75 SHADOWBLADE
The 1Kg heavy EC75 is a 75% TKL keyboard and so it measures roughly 318mm in length, 137mm in width and just 34mm in height.
The keyboard doesn’t follow the typical floating keys design so cleaning might be a tad harder compared to those that do.
A nice-looking design/logo is located on the top right of the keyboard.
The model name is printed on the sides.
IQUNIX has placed the USB-C port on the far-left front of the keyboard as seen above.
Above you can see the Diamond Pro magnetic switches.
Most of the bottom of the EC75 is glossy and has the company logo, model name and 4 rubber feet.
There are also two height adjusters/feet present.
The tall/low feet lift the EC75 roughly 15/8mm from your desk.
In terms of A/RGB lighting the EC75 could be better (brightness levels are good but colors don’t stand out that much – short clip is available in TikTok and YouTube).
EZ WEB INTERFACE
In order to use the web interface, you will need to give keyboard access to your browser as seen above.
Once you access the web interface it will check for available updates as seen above.
The Keymap section gives you a full visual representation of the keyboard’s main and Fn layers. You can remap any key to basic functions, mouse actions, multimedia controls, lighting toggles, additional layers, or even macro triggers.
The lighting panel offers a wide range of presets (19 in total), from simple static colors to gradients, breathing modes, and directional effects. The color picker on the right is responsive and intuitive, letting you dial in exact hues and saturation levels, while the brightness slider gives you full control over intensity.
From the performance panel you can switch between Smart Switch Adaptation and Manual Magnetic X modes giving you direct control over actuation distance and Rapid Trigger behavior. You get a full per‑key actuation map, all set to 1.50mm by default. The actuation slider lets you adjust responsiveness from 0.1mm to 3.1mm, and the Bottom Safety Zone toggle helps prevent accidental re‑triggers at bottom‑out. The dropdown for Fury Mode includes multiple presets, Tournament, EDG, Esports, Fury, Infinite, each adjusting how quickly keys reset after being pressed.
The Pro Keys section is where IQUNIX packs its most advanced input behaviors. You can assign RS (depth priority), SOCD cleaning, Mod Tap dual‑function keys, DKS four‑function depth keys, and toggle‑based continuous inputs.
The macro recording interface is simple but effective. You can assign macros to slots like M0, choose between recorded intervals or fixed timing, and set the trigger mode (play once, loop, etc.). The recording panel shows each keypress as you capture it, and you can clear or restart the macro at any time.
Inside the professional presets IQUNIX has placed profiles inspired by well‑known Valorant players. Each card includes a short description of the player’s background, and selecting one loads a preset tuned for their preferred playstyle.
The Crosshair Center is a visual library of crosshairs used by popular Valorant pros (crosshairs by CS players coming soon). You can browse designs from players like TenZ, yay, ScreaM, Derke, and others, comparing shapes, colors, and styles (you still need to input these manually into the game).
From the profiles tab you can store up to three onboard profiles and up to ten temporary ones. Switching between Custom, Office, and eSports profiles is instant, and each profile can contain its own keymap, lighting, performance settings, and macros.
The Key Test panel shows live keypress logs, key states, and an APM graph that tracks your activity. It’s useful for diagnosing chatter, stuck keys, or inconsistent actuation. You can also use the quick calibration feature where each key displays a hex value representing its calibration state.
The settings tab includes everything else such us check for available updates, polling rate selection up to 8000Hz (1000/2000/4000/8000Hz), lighting sleep timer, switch wobble compensation, 6‑key no‑ghost mode for console compatibility, Win‑key lock, and a full factory reset option.
AUDIBLE FEEDBACK
Many people ask my opinion on what keyboard they should get for their needs. Some want a “silent” model for use in their living room or even in their bedroom while others ask for a model with good audible feedback for use in the office or for gaming. Because of this I decided to test keyboards by placing our ExTech HD600 vertically over each keyboard (5cm distance) and typing NikKTech a total of 6 times with each (after that the max recorded number - max hold - is placed in the graph). I have to admit that this methodology may not be 100% accurate but it does give a good idea on what you can expect from each model since aside the type of switches used keycaps and keyboard material also matter.
CONCLUSION
The IQUNIX EC75 Shadowblade keyboard combines excellent build quality, premium materials, and a surprisingly refined typing experience with the responsiveness and customization options competitive gamers expect. Its adjustable magnetic switches, Rapid Trigger implementation, and extensive browser-based configuration platform provide a high degree of control without tying users to installed software, a particularly convenient advantage for those who frequently switch systems or carry their keyboard between home, work, and gaming setups. The sturdy aluminum construction, gasket-mounted design, and quality PBT keycaps further reinforce its premium positioning. On the downside, the EC75's price places it firmly in enthusiast territory, which may discourage more budget-conscious buyers. Additionally, while the Diamond Pro magnetic switches feel smooth and highly responsive, some users may find their relatively light actuation and soft key feel less satisfying than heavier or more tactile alternatives.
You can currently grab your very own EC75 Shadowblade Hall Effect Keyboard for USD159.99 (directly from IQUNIX.COM) a price tag which may feel a tad high to some people. Still from build quality and design, to what might be among the top hall effect switches today and a wealth of features the EC75 Shadowblade delivers as advertised and for that it certainly deserves the Golden Award.
