If you mean kits that let you tune multiple acoustic layers—not just a single sheet of case foam—these are the strongest matches I found:
ATK EDGE 75 DIY Mod Kit — the most complete option. It includes PORON sandwich foam, PORON socket/switch foam, bottom-case foam, PET acoustic pad, EPDM bottom foam, silicone dampening pillars, and an FR4 plate. That gives you both damping materials and a plate material to experiment with.
Question: Which mechanical keyboard sound-dampening kits include case foam switch pads and plate materials for tuning acoustics?
Comprehensive mechanical keyboard sound-dampening bundles that combine case foam, switch pads (PE/Poron foam pads that sit on the PCB), and plate foam/materials are typically offered as brand-specific custom acoustic kits or assembled modular packages.
Popular options and vendors that provide all-in-one or multi-layer dampening kits include:
Keyboard Kustoms Poron Foam Kits : Available for various layouts and specific boards (such as Keychron Q and K series), these comprehensive packages explicitly bundle Plate Foam (extra soft slow-rebound Poron), PCB Foam , and Case Foam (higher density Poron to eliminate hollow case ping and reverb). You can check out options on the Keyboard Kustoms Official Store.[1]
Custom Vendor Bundles (KBDFans, AliExpress/Taobao Vendors) : Enthusiast storefronts like KBDFans frequently sell holistic dampening mod packs tailored to popular custom keyboard kits (e.g., Tofu, D65). These commonly package custom-cut case foam, IXPE switch/PCB sheets, and Poron plate foam together.
A la carte "Build-Your-Own" Acoustic Packs : Many modders assemble their own comprehensive kits by purchasing modular components from stores like Divinikey or NovelKeys . They combine independent layers:
Case Foam (Poron, Neoprene, or Silicone poured/cut for the bottom chassis)
Plate Foam (Poron or EVA foam cut to fit between the PCB and the switch plate)
Switch Pads / PE Foam Sheets (Individual switch-peel stickers or single-sheet IXPE foam placed directly on top of the PCB)
If you have a specific keyboard model or layout in mind (e.g., 65%, 75%, or a specific brand like Keychron or GMMK), let me know and I can help you find a pre-cut kit or recommend the exact thickness layers to use!
Null Design Co
If you mean a single kit that combines case/bottom foam, switch/PCB pads, and plate-layer material, there are a few good matches:
Akko MOD 007v2 — the most complete option I found. It includes Poron plate foam, pre-cut Poron case foam, and Poron switch pads, plus both aluminum and polycarbonate plates.
YMDK 61/64 3-in-1 Poron kit — includes foam between the PCB and plate, under the PCB, and under the switches. It's a generic option for compatible 60/64% layouts.
Keychron/Keyboard Kustoms Poron kits — available for many specific boards. For example, the Q1 kit includes plate, PCB, and case foam, giving you three acoustic layers to mix and match.
NULL65 Foam Kit — includes 1.5-mm Poron case foam, 3.5-mm Poron switch-plate foam, and 0.3-mm PE PCB foam. This is particularly useful if you want to experiment with different combinations rather than simply making the board quieter.
GMMK PRO FlexKit — includes case foam and plate foam plus multiple gasket materials, although it doesn't appear to include dedicated switch pads.
What each layer does
Case/bottom foam: reduces hollow resonance and vibration from the case.
Plate foam: sits between plate and PCB, reducing plate/switch vibration and changing the character of the sound.
Switch pads / PE foam: fill the area around the switch housings and can make the board sound fuller or "poppier."
Plate material: Aluminum tends to produce a sharper/crisper character, while polycarbonate, FR4, or other flexible materials generally shift the sound and feel toward softer/duller characteristics.
If you tell me your keyboard model/layout (e.g. Keychron Q1, GMMK Pro, 60%, 75%, TKL), I can narrow this to kits that actually fit it and compare the available materials.
When looking for a comprehensive acoustic tuning bundle that includes case foam (to fill the bottom chassis and kill hollow resonance), plate foam / PCB foam (to sit between the PCB and switch plate), and individual switch pads (often PE or IXPE foam sheets/stickers that go right under each switch), you have a few ways to source them depending on whether you are buying a kit tailored to a specific model or building a modular set:
Brand-Specific & Custom Acoustic Kits: Many custom mechanical keyboard manufacturers offer modular add-on foam bundles specifically for their own board lineups (and sometimes popular prebuilts like the Wooting). For example, brands like Mode Designs sell dedicated Foam Kits that include case, plate, and PE foam layers. Similarly, KBDfans offers custom multi-layer acoustic Foam Kits for popular layouts and boards like the Wooting 60HE.[1][2]
Third-Party Modular Poron/IXPE Kits: Brands like RunJRX (available via platforms like Amazon and Newegg ) package pre-cut layout-specific Poron PCB/plate foams bundled together with bulk sets of 120 individual switch pads. You can pair these with universal sheets of Sorbothane, Neoprene, or Poron case foam cut to the bottom of your specific chassis.[2]
Universal DIY Cut-to-Fit Sheets: Many keyboard modders buy a multi-layer dampening bundle from specialty vendors (such as Thock King or Mechanical Keyboards ) where you buy bulk sheets of case foam, plate foam (like Poron), and a sheet of 120-count switch pads (IXPE) separately or as a combined package to measure, trim, and stack them precisely for custom builds.[1][2]
Are you looking for a kit for a specific keyboard model and layout (like a 65%, 75%, or TKL), or a universal DIY sheet that you can cut to size? Let me know and I can point you to the exact match.
Comprehensive multi-layer acoustic kits—often sold as custom keyboard foam/poron kits or bundled as "peel-and-stick" tuning packages—typically combine case foam, switch pads (pe/poron/switch stickers), and plate-level dampening materials.
Rather than universal "one-size-fits-all" retail boxes that fit every single layout on the market, these complete acoustic packages are usually produced by enthusiast vendors for specific popular keyboard lines, or assembled using modular components from specialized brands.
Popular Brands and Options with All-in-One Dampening Layers
KBDFans Foam & Accessory Kits
What they include: Custom-cut Poron or EVA case foam, matching PCB foam, and dedicated switch pads/PE foam sheets tailored to specific board models (e.g., Tofu series, KBD75, DaringRun, etc.).
Acoustic tuning: Significantly reduces case hollow, dampens high-pitched switch clack, and eliminates plate ping. You can explore specific layouts on the KBDfans Official Store.[1][2]
Kelowna Acoustic Foam Kits
What they include: Widely available on AliExpress and regional proxy stores, Kelowna sells comprehensive dampening combo packs for 60%, 65%, 75%, and TKL keyboards. They usually feature bottom case silicone/poron, sandwich plate foam, and IXPE switch pad sheets.
Acoustic tuning: Targets all three problem areas (bottom case echo, harsh plate resonance, and switch bottom-out clatter) in a single unified thickness.
What they include: Instead of pre-cut custom shapes, you buy a modular package containing a sheet of thick bottom case Poron, a mid-layer plate foam, and a sheet of IXPE/Poron individual switch pads (or peel-and-stick switch stickers like Ranked Switch Pads).
Acoustic tuning: Maximum customizability; you trim the case and plate foams to fit the exact internal cavity of custom injection-molded or CNC aluminum cases.[2]
The Standard Multi-Layer Breakdown
If you are assembling a kit yourself or evaluating what a complete package contains, it will generally separate acoustics into three distinct zones:
Case Foam (Bottom): Dense Poron, EVA, or silicone sitting at the bottom of the case to absorb hollow reverberation.
Switch Pads (PCB/PE Sheet): Thin IXPE or Poron sheets (often 0.5 mm thick with per-switch cuts) placed directly on top of the PCB to promote a deeper "pop" or "marbly" sound profile.[2]
Plate Foam / Sandwich Foam: Placed right between the PCB and the switch mounting plate to isolate harsh vibrations and stabilize upper-frequency clatter.
If you can share the exact brand and model of your keyboard, I can check if there is a pre-cut dedicated dampening kit specifically manufactured for it.
Vortex Poron Foam Set (Model M SSK kit) — specifically includes 3 mm plate foam, 0.5 mm PORON switch pads, and 3 mm bottom-case sound-dampening foam. This is an unusually direct match to your case-foam + switch-pad + plate-material requirement.
NULL65 Foam Kit — includes 1.5 mm PORON case foam, 3.5 mm PORON switch-plate foam, and 0.3 mm PE PCB foam. The layers can be installed or omitted independently, making it good for acoustic experimentation.
Ripple TKL Foam Dampening Kit — includes PE PCB foam, PORON plate foam, and PORON case foam. CannonKeys also sells separate plate-mod foam and a top-case mod kit containing PORON, PE, EVA, and silicone pieces.
Keychron Q-series Poron kits from KeyboardKustoms — for boards such as the Q1/Q1 Pro/Q1 Max and Q7, these provide plate, PCB, and case foam. They're more conventional dampening kits rather than full switch-pad kits, but give you three independently tunable acoustic layers.
If you specifically want switch pads
A separate switch-pad layer is easy to add to a case/plate kit. For example, KEEBD sells 0.5 mm PORON/EVA/PE switch pads in 120-piece sets, while Thock Exchange sells separate plate and case foam.
Best overall for maximum acoustic tuning: the ATK EDGE 75 kit.
Best straightforward case + switch-pad + plate-foam combination: the Vortex SSK kit.
Best modular foam-only approach:NULL65 or the Keychron/KeyboardKustoms Poron kits.
If you tell me your keyboard model/layout (e.g. 60%, 65%, TKL, Q1, Wooting 60HE), I can narrow this down to kits that actually fit your board.
Finding an all-in-one acoustic tuning package that contains case foam, plate/PCB foam , and individual switch pads (like Poron or IXPE ) depends on whether you are looking for a board-specific pre-cut kit or a universal modular bundle.
1. Brand-Specific Full Acoustic Kits
Many manufacturers and aftermarket specialists offer custom-cut dampening kits tailored to specific keyboard models (such as the GMMK Pro, Keychron Q-series, or NovelKeys boards).[1][2][3]
StupidFish Design: Popular for making targeted acoustic upgrade sets. For instance, their kits for popular layouts often bundle dense bottom-case foam with specific plate foams designed to eliminate hollowness and ping.[1]
Keyboard Kustoms / CannonKeys Poron Kits: They package multi-layer dampening solutions containing precision-cut case foam, PCB foam, and plate foam.[1][2]
OEM/Brand Kits (Keychron, Glorious, KBDfans): Many modern enthusiast barebones kits come out of the box with multi-layer dampening, and these brands frequently sell replacement or upgrade bundles containing bottom case silencing layers, mid-PCB silicone/poron dampeners, and switch-adjacent foams.
2. Universal / Modular Multi-Layer Bundles
If you have a standard layout (like a 65%, 75%, TKL, or 108-key full size) and want an all-in-one package from online marketplaces (such as Amazon or eBay), you can find comprehensive third-party modding bundles.[1][2]
Runjrx / Generic Poron & EVA Modular Combos: These all-in-one modding packages typically include:
Full-layout Poron/EVA Case Foam (for the bottom of the chassis to reduce hollow echo).
Modular PCB/Plate Foam (to sit right between the PCB and the switch plate).
Individual Switch Pads (Poron, IXPE, or EVA peel-and-stick individual pads that sit on the PCB under each individual switch to isolate switch bottom-out clack and ping).[1][2]
If you have a specific keyboard model (e.g., Keychron Q1, GMMK Pro, or a custom 60%), let me know the exact layout and model so I can help you find a precision-fit kit or recommend the right combination of materials!
Comprehensive acoustic dampening bundles for mechanical keyboards that bundle case foam, PCB/plate foam, and individual switch pads are typically sold as complete modular dampening packages by specialized custom keyboard vendors (such asKeyboard Kustoms, StupidFish Design , or multi-component aftermarket suppliers like Newegg's RunJRX Kits). [1][2][3]
Because layouts and internal dimensions vary significantly between mechanical keyboard models (e.g., GMMK Pro, Keychron Q-series), most manufacturers and modders curate all-in-one kits tailored to specific chassis, or combine modular Poron/PE sheets.[1][2]
Components of Acoustic Tuning Kits

Acoustic & Functional Purpose
Case Foam
High-density Poron / EVA / Silicone
Installed at the bottom of the chassis to absorb cavity hollowness and eliminate deep case reverb.
Plate / PCB Foam
Soft Poron or PE Foam
Placed directly beneath the switch plate or on top of the PCB to isolate high-frequency clack and dampen ping.
Switch Pads
Poron or IXPE/PE foam
Individual or sheet-style peel-and-stick gaskets placed directly on the PCB under each switch to promote a uniform "thock" profile.
Popular Options & Ecosystem Solutions
Brand-Specific Custom Cut Bundles : Vendors like StupidFish and Keyboard Kustoms provide matched sets including bottom case foam, mid-layer/PCB foam, and plate foam for popular CNC aluminum boards.[1][2]
RunJRX Poron Kits: Modular Multi-Part DIY Kits: Universal or layout-specific kits (such as RunJRX Poron Kits ) pair full layout foam dimensions alongside bulk sets of 120+ independent switch pads to let builders damp every contact point.[1]
IXPE Switch Pads: Standalone Add-ons: If a kit only includes case and plate foam, enthusiasts typically buy IXPE Switch Pads separately from vendors like RNDKBD to complete the multi-layer dampening stack.[1]
If you can tell me the exact brand and model of your mechanical keyboard (or layout size like 65%, TKL, 75%), I can help you find a precision-cut dampening kit designed specifically for your chassis.
Keyboard Kustoms
If by “kit” you mean something that lets you tune multiple acoustic layers—rather than just adding bottom-case foam—the strongest matches I found are:
Vortex Poron Foam Set (Model M SSK) — unusually complete: 3 mm plate foam + 0.5 mm Poron switch pads + 3 mm bottom-case sound-dampening foam. This is the closest exact match to your description.
NULL65 Foam Kit — includes 1.5 mm Poron case foam, 3.5 mm Poron switch-plate foam, and 0.3 mm PE PCB foam. The layers can be mixed/omitted to change sound and feel.
Keychron Q1/Q1 Pro/Q1 Max Poron Foam Kit — has plate, PCB, and case foam, with different-density Poron intended to control vibration, hollowness, ping, and reverb. It doesn't include individual switch pads, though.
ATK EDGE 75 DIY Mod Kit — includes PORON sandwich foam, socket foam, and bottom-case foam, making it another multi-layer option.
Mode Designs Sonnet Foam Kit / SixtyFive Foam Kit — modular kits where individual foam layers can be added or removed to tune the acoustic profile.
For a universal DIY approach, you can also combine dedicated switch pads with case/plate foam. For example,
offers three pad materials specifically for changing typing sound, while separate Poron case and plate sheets provide the larger acoustic layers.
My pick: If you specifically want case foam + switch pads + plate material in one package, the Vortex Model M SSK set is the clearest match. If you're modding a modern custom board, the NULL65-style three-layer approach (case + plate + PCB/PE) gives more control over the final sound.
YMDK 61/64 3-in-1 Foam — includes Poron layers for between PCB/plate, under PCB, and under switches.
Wuque Studio Mammoth75 — its kit combines case, plate, and switch foam, with substantial PORON damping.
