What customers say
Customers consider the Freebird75 case and plate foam set an essential upgrade, primarily due to its dramatic acoustic improvements. Reviewers consistently praise the precision cut foam for perfectly filling the case, effectively eliminating hollowness and metallic ping. This results in a significantly deeper, cleaner, and more satisfying sound profile, often described as thocky or marbly. Installation is straightforward because of the exact fitment, showcasing excellent quality control. While the initial price might cause hesitation, users quickly recognize the set offers immense value. It elevates the Freebird75 keyboard's sound performance to levels comparable with much more expensive custom builds, making it a necessary investment for sound maximization.
Know before you buy
This foam set is specifically engineered for the stock Keebsforall PCB included with the Freebird TKL. If you are using an aftermarket or third-party PCB, the cutouts may not align correctly.
The 3mm foam layers help dampen hollow resonance and high-pitched pinging, resulting in a more solid, muted, and consistent typing sound. It also provides a slightly firmer tactile response by filling the empty space within the case.
Yes, you should select the configuration that matches your current build. The foam cutouts are specifically tailored to accommodate the different mounting styles, ensuring a proper fit without interfering with the board's flex.
Installation is straightforward and requires basic disassembly of your keyboard. You simply place the plate foam between the plate and PCB, and the case foam at the bottom of the chassis before reassembling.
Absolutely. Using both the 3mm plate foam and 3mm case foam provides the most comprehensive acoustic dampening, though you can choose to use only one if you prefer a slightly different sound profile.
