Verdict: The VANZACK six-pack is marketed for home studios and quieter rooms, but the seller’s description does not establish soundproofing or a measurable reduction in noise through a wall. If the listed material and dimensions are accurate, these are small surface-treatment panels that may alter reflections within a room. We have not found product-specific laboratory results to quantify that effect.

Six panels, but how much useful coverage?
The seller describes six grey pieces measuring about 30 × 30 × 4 cm each. If all six dimensions are correct and the panels lie flat, their combined face area is 0.54 m² (approximately 5.8 ft²). That is a small treatment area, especially in a room with many hard surfaces. The four-centimetre depth alone cannot tell us their absorption at different frequencies.
| Listing item | Stated detail | Verification gap |
|---|---|---|
| Pack | Six grey panels | Consistency across supplied pieces |
| Dimensions | 30 × 30 × 4 cm per panel | Thickness and size tolerances |
| Material | Described as polyurethane or “rubber cotton” | Exact composition and tested absorption coefficients |
| Claimed use | Walls, ceilings, doors and recording rooms | Suitability of adhesive/mounting for each surface |
| Fire performance | “Fire retardant” appears in marketing | Actual standard, test report and classification |
The difference between a clearer room and a quieter neighbour
Porous panels can influence sound that reflects off surfaces. That may be useful if speech sounds splashy or a microphone captures noticeable room reverb. But it does not follow that the same panels can stop external traffic, bass from a neighbour or speech travelling through a partition.
Acoustics manufacturer Auralex distinguishes acoustic absorption from isolation: absorption addresses room sound, whereas sound isolation depends on the construction of the separating assembly. We therefore would not use the seller’s “soundproofing” wording as proof of transmission loss.
Where this small pack might be worth trying
For a compact desk recording setup, trial placement at an obvious reflection point can be more meaningful than covering an arbitrary decorative rectangle. Record a voice sample before mounting anything. Then, temporarily position the panels safely and record again with identical microphone settings. Listen for a repeatable change. Avoid assuming any improvement will extend to low bass frequencies.
For a larger room, six pieces will not provide comprehensive treatment. If acoustic measurements matter, choose products with published absorption coefficients at relevant frequencies and compare the total treated surface area, thickness and mounting conditions.
Two checks before fixing foam to a wall
- Ask for fire documentation. “Fire retardant” is not a substitute for a named standard and verifiable classification. Follow local building requirements, especially in shared or commercial spaces.
- Confirm the mounting method. Adhesives can mark paint; ceiling installation raises additional attachment and safety considerations. The listing does not prove compatibility with every substrate.
Should you buy VANZACK for soundproofing?
Not if “soundproofing” means keeping noise in or out. These six small panels may be considered only for modest indoor reflection control, with performance still unverified. For serious sound isolation, investigate leakage paths and wall, door or floor construction first; for dependable room treatment, look for independent acoustic test data.
