Premium 65% Keyboard Poron Foam Kit
Best acoustic upgrade for 65% mechanical keyboard enthusiasts.
Enhance your keyboard's acoustics with this premium Poron foam kit, designed for 65% and 68-key standard ANSI layout keyboards. Poron open-cell foam is highly effective at reducing unpleasant sounds and amplifying desirable typing acoustics, while also eliminating hollowness and ping. The kit includes plate foam (which may require minor modifications for screw cutouts) and two sheets of case foam (2mm and 4.5mm) to perfectly fit the space below the PCB within your keyboard case, improving sound dampening and typing feel.

Know before you buy
This kit is designed for standard 68-key ANSI layouts. While it fits most standard 65% boards, the plate foam may require minor trimming or additional screw cutouts depending on your specific PCB and mounting style.
The two thicknesses allow you to fine-tune the internal volume of your keyboard case. You can use the 2mm sheet for tighter cases or the 4.5mm sheet to fill larger gaps and maximize sound dampening.
Poron foam provides a subtle, cushioned sensation that absorbs the harsh vibrations of bottoming out. It creates a more consistent, dampened typing experience compared to the hollow feel of an empty plastic or metal case.
Yes, the foam is highly effective at absorbing the high-frequency vibrations that cause metallic pinging. By filling the empty space beneath the PCB, it prevents the case from acting as a resonance chamber for those unwanted noises.
Yes, installation requires removing the keycaps and switches, and opening the keyboard case to place the foam between the PCB and the bottom housing. It is a straightforward process, but you will need basic tools to open your specific keyboard model.
