What customers say
The KBDfans KBD75 PCB Foam is overwhelmingly praised as an essential acoustic upgrade. Customers consistently highlight its perfect drop in fit, noting the precise dimensions eliminate any need for trimming or modification. The core benefit is the dramatic sound improvement. Users report the foam effectively dampens case resonance, removing hollow sounds and metallic ping. This results in a cleaner, deeper, and more satisfying typing sound profile. Enthusiasts view this foam as foundational for achieving a premium sound on the KBD75. The acoustic transformation achieved strongly justifies the cost, making it an excellent value for dedicated keyboard modders seeking superior sound quality.
Know before you buy
No, this specific foam is engineered exclusively for the KBD75 V1 and V2 models. It will not fit newer iterations due to differences in the PCB and plate layout.
The foam is designed to be placed directly between the plate and the PCB. You will need to disassemble your keyboard and remove the switches to install it properly.
While its primary purpose is acoustic, the 3.5mm thickness provides a slightly more cushioned typing feel. Most users find it makes the bottom-out experience feel a bit more solid and less hollow.
No adhesive is required. The foam is held securely in place once you install your switches through the plate and into the PCB, which compresses the foam for a snug fit.
The foam is designed to accommodate standard switch layouts, but it may partially obstruct or diffuse per-key RGB lighting depending on your specific PCB configuration. If your lighting is mounted on the top of the PCB, you may notice a slight reduction in brightness.
