What customers say
This foam set is highly regarded for dramatically improving keyboard acoustics. Users consistently praise its effectiveness in eliminating spacebar hollowness and the irritating ping sound. The modification transforms a sharp clack into a deep, satisfying thock, significantly enhancing the typing experience. The inclusion of a three pack with varying thicknesses is a major benefit, offering crucial flexibility to achieve the perfect fit across different keycap profiles. Despite minor installation adjustments needed for some spacebars, the resulting acoustic improvement is viewed as a high impact upgrade. The foam's quality and density deliver a premium, muted sound signature that enthusiasts consider essential.
Know before you buy
No, these foams are specifically engineered for PCB-mount stabilizers. They are not compatible with plate-mount or Costar stabilizer systems.
No modification is required. The foams are pre-cut to fit standard 6.25u and 7u spacebars, allowing for a straightforward, drop-in installation.
The 6mm foam acts as a dampener to reduce hollow sounds and resonance inside the spacebar. It creates a more solid, muted acoustic profile when you bottom out.
These are designed for Cherry MX-style switches. As long as your keyboard uses Cherry-style PCB-mount stabilizers and standard MX switches, the foam will fit correctly.
Each pack includes three 6.25u foams and three 7u foams, providing enough material to dampen up to six spacebars total.
