Who it fits

Key specs explained for this keyboard

Form Factor: 75%

This layout keeps the number row and function keys while removing the numpad. You get a compact footprint that saves desk space but retains essential keys. It suits users who need arrow keys and shortcuts without the bulk of a full-size board. This balance is ideal for gamers and typists who want efficiency without sacrificing utility.

Switch Type: Pre-lubed linear

Linear switches move straight down without a tactile bump. Pre-lubrication reduces friction, creating a smooth and quiet typing feel. You benefit from consistent keystrokes that are gentle on your fingers. This setup is excellent for rapid gaming inputs and long typing sessions, offering a creamy sound profile that minimizes distracting noise.

Connectivity: Bluetooth, 2.4GHz wireless, wired

Tri-mode support lets you connect via Bluetooth for multiple devices, 2.4GHz for low-latency wireless, or a cable for stability. You can switch between your computer, tablet, and phone easily. The wired option ensures zero lag during intense gaming. This flexibility allows you to adapt your setup to any environment or device preference.

Keycap Material: Double-shot

Double-shot keycaps are molded from two layers of plastic, making the legends permanent. They will not fade or wear off over time, even with heavy use. You get durable keycaps that maintain their appearance for years. This construction is a mark of quality, ensuring your keyboard looks sharp and remains readable throughout its lifespan.

Backlighting: RGB

RGB lighting provides customizable color effects for each key. You can choose from multiple built-in modes or use software to create custom patterns. This feature enhances visibility in low light and adds personal style to your desk. It allows you to match your setup aesthetic or use specific colors to highlight important keys.

Design and build overview

The B75 PRO measures 13 inches in length, 5.6 inches in width, and 1.65 inches in height. It weighs 1.98 pounds. These dimensions define a compact 75% layout. You retain the number row and function keys while saving desk space compared to a full-size board. The grey finish is available in multiple color options, including purple and olive green, according to the listing. This allows you to match your desk setup without altering the core structure.

The listing describes a gasket mount design with five layers of padding. This construction aims to reduce noise and provide a solid typing feel. The keyboard uses double-shot keycaps, which are known for durable legends that resist fading over time. South-facing LEDs are included, directing light toward the user for even illumination. A multifunction knob sits on the top right. You can use it to adjust volume and backlight effects quickly without reaching for software.

Under the hood, the PCB supports hot-swappable sockets for both 3-pin and 5-pin switches. You can change the switches to alter the typing feel without soldering. The pre-lubed linear switches reduce friction and noise. The 4000mAh battery supports Bluetooth, 2.4GHz wireless, and wired connections. This tri-mode setup ensures you can use the keyboard with various devices. The physical design prioritizes a clean aesthetic and practical controls for daily use.

Setup and daily operation

The B75 PRO supports three connection modes: Bluetooth, 2.4GHz wireless, and a wired USB link. You can switch between these options to suit your device. The listing notes compatibility with Windows and MacOS systems. This broad support means you can pair it with most computers and laptops without driver issues. The included 4000mAh battery provides extended usage time. This capacity suggests you can use the wireless modes for long work sessions or gaming without frequent recharging. The keyboard includes a multifunction knob on the top right. You can rotate this knob to adjust volume and RGB backlight brightness. A long press on the knob switches between gaming and office modes. This physical control offers quick adjustments without using software. The listing mentions programmable software for customizing keys and macros. You can redefine key functions and set macros through this program. The software also allows you to customize RGB effects. The keyboard features south-facing LEDs. This design choice typically allows for taller keycaps without blocking light. You get double-shot keycaps for durability. The hot-swappable sockets accept 3-pin and 5-pin switches. This feature lets you change switches to alter typing feel without soldering. The gasket mount structure and five-layer padding are designed to reduce noise. The pre-lubed linear switches aim for a smooth keystroke. These specs indicate a focus on customization and quiet operation for daily tasks.

Before you buy this keyboard

You should verify that your workspace can accommodate a 13-inch device. The B75 PRO requires a stable surface for its gasket mount structure to function correctly. You must choose between Bluetooth, 2.4GHz wireless, or wired operation based on your setup. If you prefer wireless freedom, ensure you have a 2.4GHz receiver port or sufficient Bluetooth channels. The 4000mAh battery supports extended use, but you will need to charge it periodically via the included cable. Since the switches are hot-swappable, you can change them later without soldering. This flexibility allows you to adjust the typing feel over time. You should also confirm that your operating system, whether Windows or MacOS, supports the programmable software for macro customization. This keyboard fits well alongside other compact options if you value space efficiency and customization. It suits users who want a tactile upgrade without expanding their desk footprint. Keep the keycaps clean with a soft cloth to maintain the double-shot material. Avoid using harsh chemicals that might damage the keycap legends or the grey finish.

Check before you buy

• Check if your desk has enough space for the 13-inch length.
• Confirm your computer supports the desired Bluetooth or 2.4GHz connection.
• Ensure you have a USB port for charging the 4000mAh battery.
• Verify your OS supports the programmable software for key remapping.
• Decide if you need the number row for your daily tasks.
