SPECIFICATIONS

Redragon K686 PRO», also known as the EISA K686 PRO — a compact 98‑key wireless mechanical keyboard with gasket mount, hot‑swap support, RGB, knob control, and five layers of noise‑dampening:

🔧 Design & Layout

• Form Factor: 98‑key layout (~96%) that retains full Function row, arrow keys, and numpad, while shaving off approximately 20% in footprint compared to a standard full‑size keyboard 

• Knob Control: A single rotary knob in the top‑right corner handles volume, media controls, backlight brightness, and mode switching—streamlining control without consuming extra key rows 

• Win/Mac Mode Toggle: Dedicated side switch to toggle between Windows and macOS layouts, aiding seamless cross‑platform use 

🧩 Switches, Mount & Sound Dampening

• Switches: Comes with pre‑lubed custom linear switches—often labeled “Red Linear” or “Leopard L”—offering a creamy, light-touch typing feel. The upgraded hot‑swap sockets support both 3‑pin and 5‑pin mechanical switches 

• Gasket Mount Design: Internal cushioning via gaskets instead of screws creates a softer, less rigid typing experience, absorbing some vibration noise

• 5‑Layer Noise Dampening: A comprehensive foam system consisting of PO foam, IXPE switch foam, PET sound pad, bottom socket foam, and silicone bottom pad (plus the gasket itself) noticeably reduces ping and hollowness for a quieter acoustic profile 

🌐 Connectivity & RGB

• Tri‑Mode Support: USB‑C wired, 2.4 GHz wireless (via included nano dongle), and Bluetooth 3.0/5.0 modes—switch between devices seamlessly and pair up to three Bluetooth devices in many implementations 

• RGB Lighting: Features full per‑key RGB with 16.8 million colors, roughly 17 preset effects, music sync, and custom effects via Redragon’s software (macros, remaps, lighting profiles) or onboard controls 

• South-Facing LEDs: LEDs are directed downward, which may limit shine-through on thicker keycaps or double-shot PBT 

🎯 Keycaps & Software

• Keycaps: Some K686 PRO versions include side‑printed gradient PBT keycaps (particularly the gradient black edition). These resist shine and fading, and feature consistent legends even when unlit 

• Software Support: Custom lighting, macro assignment, remapping, and profiles are programmable via Redragon’s official software. On‑board Fn layer controls also allow customization without software 

📦 Build & Included Accessories

• Weight & Dimensions: Around 0.97–1.20 kg depending on model; dimensions approximately 16.9 × 7.48 inches with a thickness of ~1.5–2.3 inches 

• Included Items: USB‑C cable, nano wireless receiver, keycap & switch puller, four spare switches, sticker, and manual 

📊 Feature Summary

The Redragon K686 PRO stands out as one of the most feature-loaded budget gasket keyboards: triple-mode wireless, high-end damping, per‑key RGB, hot-swappable switch support, and a multifunction knob—all in a compact footprint at a competitive price point (often in the ~$60‑90 USD range depending on region).
