8K Hz Polling Rate & Ultra-Low Latency
The C68 boasts an 8000Hz polling rate and 64K Hz key scanning frequency, resulting in an ultra-fast 0.125ms response time. This significantly reduces input lag, providing a competitive edge in demanding applications and games.

Triple-Layer Sound Dampening System
For a smooth and satisfying typing experience, the C68 incorporates a triple-layer sound dampening system. This includes a thick EVA sound dampener, a sound-absorbing foam, and a bottom silicone pad, effectively reducing hollow sounds and cavity noise.

65% Layout with PBT Keycaps & RGB Lighting
The compact 65% layout with 68 keys maximizes desk space while retaining essential arrow and function keys. The durable, oil-resistant MDA profile PBT keycaps resist shine and wear. The keyboard features over 20 vibrant south-facing RGB lighting effects, customizable to match your setup and enhance your environment.

Advanced Magnetic Key Functions
The C68 offers several advanced functions for enhanced control in various game genres:
- Dynamic Keystroke (DKS): Trigger 2-4 functions based on different press levels of a single key. For example, a light press for walking and a full press for running in RPGs.
- Multi-Tap (MT): Execute multiple actions with a single key press, useful for complex combos in MOBA games.
- Toggle (TGL): Enable continuous triggering with a click, and press and hold to cancel, ideal for 'hold-to-sprint' actions in FPS games.
- SOCD Cleaning: Ensures flawless directional inputs, particularly beneficial in fighting games.

Maintenance
Cleaning
- Use the provided dust cover when the keyboard is not in use to prevent dust accumulation.
- Gently wipe the keycaps and keyboard body with a soft, dry, lint-free cloth.
- For deeper cleaning, use the 2-in-1 keycap & switch puller to remove keycaps and clean underneath with compressed air or a small brush.
Switch & Keycap Replacement
The C68 features hot-swappable magnetic switches. Use the provided switch puller to carefully remove and replace switches if needed. Ensure replacement switches are compatible Hall Effect magnetic switches.
Troubleshooting
- Keyboard not responding: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
- RGB lighting not working: Check the keyboard's lighting controls (Fn + keys as indicated in the manual or on the keycaps) or use the web-based driver to adjust settings.
- Inconsistent key presses: Verify that the Hall Effect switches are properly seated. If issues persist, try replacing the affected switch with one of the backup switches.
