What customers say
Enthusiasts overwhelmingly praise the Parallel Sequence PE foam for its transformative acoustic results. The core theme is superior sound quality, delivering a satisfying, 'marbly' texture and rich low-frequency resonance that eliminates unwanted pings. Users value the precision engineering; the optimal density and thickness minimize keycap interference while maximizing sonic impact. While installation is generally straightforward, minor trimming may be needed for custom layouts. Although the price is higher than generic alternatives, the community consensus confirms that the consistency and quality control fully justify the premium cost. This foam is highly recommended for achieving a perfected keyboard sound profile.
Know before you buy
This foam is designed to sit between your PCB and plate to dampen unwanted vibrations and hollow sounds. It helps refine the acoustic profile of your Sequence keyboard, resulting in a cleaner, more consistent typing sound.
No, this specific foam is precision-cut exclusively for the Sequence keyboard by Parallel. It will not fit other keyboard layouts or models due to the specific mounting points and dimensions of the Sequence.
You should choose the size that matches the spacebar layout of your specific Sequence build. If you are using a standard bottom row, you likely need the 6.25u version, while the 7u version is for Tsangan or HHKB-style layouts.
At 0.5mm, the foam is thin enough to ensure that your Cherry MX style switches can still snap securely into the plate without interference. It provides acoustic benefits without compromising the structural integrity of your switch connections.
While the cross-linked PE foam is durable, it is intended as a semi-permanent installation. Repeated removal and re-installation may cause the foam to stretch or tear, so it is best to treat it as a single-use component for your build.
