【Tri-Mode Connectivity for Multi-Device Workflow】Connect via USB-C, 2.4GHz wireless, or Bluetooth 5.0 (3 channels supported), with ultra-low latency (USB 2ms, 2.4G 5ms, BT 11ms). Switch seamlessly between Windows and Mac to work across your PC, laptop, tablet, smartphone, or gaming console. Perfect for programmers, students, creators, hybrid workers. The built-in 4000mAh rechargeable battery ensures stable wireless performance. Continue typing while charging via wired mode when power runs low

【Creamy Thocky Typing Sound】The gasket mount absorbs harsh vibrations and hollow echoes to produce a smooth marbly thock, rather than loud clacky taps. Each keypress feels softly cushioned. Whether you’re working late at home or typing in a shared office space, the mellow, ASMR-like tone makes every keystroke a genuinely enjoyable experience

【Hot-swap for Tailored Sound & Tactile】Pre-lubed Bsun linear switches (45-50gf actuation) deliver a buttery response. Compatible with both 3 pin and 5pin switches, they enables solder-free swapping. From beginners to frequent typists and dedicated writers, craft your preferred typing signature without complex modding

【RGB Backlighting & Programmable】A warm ambient glow surrounds PBT keycaps and case edges, creating a calm, inviting desk vibe for late-night workspace. Adjust hues and brightness through shortcut keys or companion software. The KN104 driver (Windows only, wired/2.4G mode) lets you remap keys and set custom macros to boost your daily productivity

【Helpful Reminders】All Kisnt keyboards use the same core parts (switches, gaskets, foam, PCB, case). Sound/feel vary with case cavity and plate layout; perception varies by user. We recommend using a wrist rest to prevent wrist fatigue from developing during extended use, which can cause discomfort and affect your focus

【2-year Warranty & Support】We treat people the way we'd want to be treated. You will enjoy 24/7 specialist support and 30-day free returns in Kisnt. We stand by our products. Whether it's damaged packaging, a quality defect, or a used item, contact us via Amazon. We're here to make it right

【Important Before You Buy】1. Charge: Fully charge before first use. A full charge ≈7–8h (may vary). Use a 5V 1A charger or a computer USB port. Fast chargers may damage the keyboard. 2. Choose static over animated effects – animated RGB drains more battery. Press Fn+↓ to dim or turn off when not in use. Power off completely during long breaks. 3. Bluetooth Pairing: Toggle to [BT], hold FN+W (or E/R) for 3–5s until key flashes rapidly, then pair with “KN104 BT-1/2/3”. Bluetooth requires Windows 8 or later & Bluetooth 4.0–5.3

If you need a full‑size mechanical keyboard that handles spreadsheets, coding, or gaming and typing comfort, the Kisnt KN104 was designed with exactly those needs in mind. The KN104 is a 100% mechanical keyboard with a dedicated number pad and a multifunction knob. It keeps every key you expect – full F‑row, arrows, navigation cluster, and numeric input – while adding media controls and volume adjustment right at your fingertips. It’s for accountants, data analysts, programmers, or anyone who relies on a number pad every day and wants a clean, productive workspace. Sound that redefines the mechanical keyboard experience. We built a gasket‑mounted structure with five layers of sound‑dampening foam (poron, silicone, etc.) to minimize hollow echoes. The result is a deep, creamy “thock” – a sound that’s noticeably more refined than the harsh clatter of traditional mechanical keyboards. It’s the kind of audio feedback that feels satisfying without being overwhelming. Wireless without worry. A 4000mAh battery delivers ≈13 hours of use with RGB on, or up to 20 days with it off. Low battery? A full charge takes 7–8 hours – and you can keep typing in wired mode while it charges. No downtime. Grows as your preferences change. Pre‑lubed BSUN linear switches (45–50gf) are smooth out of the box, and hot‑swappable sockets (3/5‑pin) let you swap in tactile or clicky switches without soldering. The rotary knob is fully programmable via the KN85 driver (Windows, wired/2.4G mode) – assign it to zoom, brush size, volume, or any custom action. From us to you. Backed by a 2‑year warranty. We listen, we refine, and we build tools you can trust. A great keyboard is never truly finished — it evolves with you, keystroke by keystroke.
