What customers say
Customers overwhelmingly view the KBDFans KBD75 Sound Dampening Case Foam as an essential and highly effective upgrade for their KBD75 keyboards. The sentiment is largely positive, bordering on enthusiastic, particularly among mechanical keyboard enthusiasts who prioritize sound profile. Users consistently praise its perfect fit, noting that the foam is precisely cut to snugly fill the empty space within the KBD75 case, which is a testament to KBDFans' attention to detail. The primary benefit highlighted is its remarkable ability to transform the keyboard's acoustics.

This acoustic improvement is often described as night and day, elevating the typing experience considerably. Installation is universally reported as straightforward and quick, requiring no special tools or expertise. While some might initially perceive it as a simple piece of foam, the tangible improvement in sound quality far outweighs its modest cost, making it an excellent value proposition for those seeking to refine their KBD75 build. The product effectively delivers on its promise, solidifying its reputation as a highly recommended modification within the community.
Know before you buy
This sound dampening foam is precision-cut to fit the KBDFans D84 and the KBD75 series, including versions v1, v2, and v3.
The foam primarily targets acoustic resonance by absorbing hollow pinging sounds. While it creates a more refined and muted sound profile, it also provides a slight dampening effect that can make the bottom-out feel feel marginally softer.
Installation is straightforward and requires no specialized tools. You simply need to open your keyboard case and place the foam insert into the bottom of the chassis before reassembling the board.
Yes, the foam is designed to sit in the bottom of the case, so it is compatible with both soldered and hot-swappable PCB versions of the KBD75 and D84.
This foam is custom-cut for the specific internal dimensions of the KBD75 and D84 series. It will not fit properly in other keyboard layouts or cases and is not recommended for use outside of its intended models.
