What customers say
Enthusiasts overwhelmingly praise the StupidFish Designs PE foam for dramatically improving the Keychron Q3's acoustic profile. The core satisfaction stems from the superior sound quality achieved, as the foam effectively removes hollow resonance from the aluminum chassis. Users report gaining the highly desired deep thock sound characteristic of premium custom builds. Installation is remarkably simple due to the foam's precise, drop-in fit requiring no modification. This ease of use, combined with the significant acoustic payoff, makes it a high-impact, low-effort upgrade. While the cost is sometimes mentioned, the consensus is that the value derived from the enhanced typing sound far exceeds the price, cementing this foam as a highly recommended component for optimizing the Q3 experience.
Know before you buy
The 0.5mm PE foam acts as a dampener that absorbs high-frequency vibrations and hollow resonance. It results in a deeper, more muted 'thock' sound profile compared to the stock configuration.
No, the foam is precision-cut for specific layouts. You must select either the ANSI Knob or ANSI no-Knob version to ensure the cutouts align correctly with your keyboard's hardware.
Installation is straightforward and requires basic disassembly of your keyboard. You simply place the foam layer between the PCB and the plate during your build or maintenance process.
The 0.5mm thickness is specifically chosen to provide acoustic benefits without significantly altering the bottom-out feel or interfering with switch seating. It is thin enough to maintain a natural typing experience while effectively modifying the sound.
No adhesive is required. The foam is designed to be held in place by the pressure of the switches and the keyboard assembly once the case is screwed back together.
