Premium Sound Pack

The C75 Premium Sound Pack uses multiple acoustic layers to create a fuller, cleaner, and more refined typing sound. PORON foam, IXPE switch pads, PET acoustic film, and slow-rebound bottom foam work together to reduce hollow noise and unwanted resonance.

The result is a deeper, more consistent, premium sound profile.

The sound-pack diagram identifies:

  • PORON sandwich foam: Separately tuned.
  • IXPE 10× switch underpad: Separately tuned.
  • PET layer: Transparent acoustic optimizer pad.
  • PORON base: Socket foam base.
  • Bottom layer: Slow-rebound bottom foam.

Ball-Catch Structure

Quick-Release Top and Bottom Case

We moved away from traditional screw fastening and integrated a precision ball-catch structure into the thick aluminum top and bottom case.

Combining high-toughness steel ball bearings with custom-positioned locating slots, it delivers a perfect fit with effortless assembly — no tools required.

This thoughtful design achieves the ideal balance between elegance and strength.

Customized Factory Pre-lubed Stabilizers

Pre-lubed out of the box, finely tuned for balance

Provides a more stable and consistent typing experience, reducing large key wobble and unwanted noise.
