The Redragon Cyrus Pro K681 WBP RGB PRO is a premium, compact 75% mechanical gaming keyboard (81 keys). It stands out by utilizing an enthusiast-grade gasket-mounted design that isolates internal vibrations to deliver an incredibly soft, comfortable typing experience and a deep, muted sound signature. 

Core Technical & Performance Specs

1. Gasket-Mounted Structure: The internal switch plate is suspended inside the case with flexible silicone dampeners. Combined with multi-layer Poron sound-absorbing foam, it completely eliminates hollow plastic echoing for a satisfying sound.
2. Tri-Mode Wireless Connectivity: Seamlessly shifts inputs using a side hardware toggle between ultra-low latency 2.4GHz wireless (via the nano receiver), Bluetooth 3.0/5.0 (pairs with up to 3 devices simultaneously), and a stable wired USB-C link.
3. Pre-Lubed Linear Switches: Out of the box, it comes loaded with factory-lubricated linear mechanical switches (often Redragon's specialized low-noise variants like Dragon Growl or Leopard L). They feature a light, smooth 40g actuation force with zero tactile bump, making them silent and highly responsive for quick double-tapping in competitive games.
4. 5-Pin Hot-Swappable PCB: Built with upgraded solderless sockets that accommodate both 3-pin and 5-pin MX-style mechanical switches (like Cherry, Gateron, Kailh, or Outemu). This lets you easily swap out the stock switches over time without any soldering.
5. Massive 4000mAh Battery: Houses one of Redragon's largest internal rechargeable batteries, providing weeks of runtime on Eco mode. You can instantly check your power levels by pressing FN + Alt—the number row will light up to display remaining charge (Green indicates above 30%, Red indicates below 30%).
