Redragon K678WG-RGB-PRO 82-Key 3-Mode RGB Mechanical Keyboard – Wired / 2.4 GHz / Bluetooth, Hot-Swap, RGB Lighting, 82-Key Layout

The Redragon K678WG-RGB-PRO is a high-versatility mechanical keyboard designed for gamers, professionals, and enthusiasts who demand performance, flexibility, and aesthetics. With a compact yet functional 82-key layout and tri-mode connectivity (wired, 2.4 GHz, Bluetooth), it offers seamless switching between devices and use cases.

Connectivity & Modes

This keyboard supports three modes of connectivity:

1. Wired (USB-C): Use this for lowest latency, fully powered operation.

2. 2.4 GHz Wireless: Ideal for near-wired responsiveness without cables.

3. Bluetooth: For flexible use with tablets, laptops, phones, or multi-device switching. 

You can switch between these modes depending on your environment — for example, use wired at your desk, and Bluetooth on the go.

Layout & Design

The K678WG-RGB-PRO employs an 82-key layout (often categorized around 78-85% style), preserving function and arrow keys while reducing blank space. This offers a balance between compactness and usability. 

It omits the numeric keypad to maximize space for mouse movement, yet retains access to essential keys (F-row, arrows, etc.).

Switches & Hot-Swap

One of the attractive features is hot-swappable sockets. You can replace switches (3-pin or 5-pin) without soldering, enabling customization or future upgrades. 

This flexibility makes the keyboard future-ready—mix and match switches or experiment with different feel profiles.

RGB Lighting & Customization

Equipped with full RGB backlighting, the keyboard supports multiple lighting modes, reactive typing effects, and color customizations. The lighting shines through keycaps and the board, enhancing the visual flair of your setup. 

Users can control lighting effects via built-in shortcuts or companion software if available.

Build & Practical Use

The chassis is made of durable materials (ABS / plastic) to balance weight and strength. The keyboard is sized modestly (approx 13.39″ × 5.51″ × 1.57″) in one listing. 

Given its wireless capabilities, the internal battery needs to be efficient—brightness and wireless usage will affect battery life.

It’s suitable for:

• Gaming (especially in wireless or wired modes)

• Productivity / coding

• Use across multiple devices (desktop, laptop, tablet)

• Enthusiasts who like to swap switches or mod keyboards

Limitations & Notes

• Wireless latency might not fully match wired in very competitive settings

• Battery life depends heavily on brightness and use mode

• Custom software support may vary by region / OS

• Compact layout may require layer keys for some functions
