Sound Proof Foam Panels, Brick Shaped Soundproof Wall Panels, 12 Pack 12"x12"x1" Sound Absorbing & Dampening Foam Panels for Walls, Room, Studio, Podcast, Acoustic Treatment

Exactly as described. The adhesive for these actually work which is rare for sound foam. BUT the adhesive is a pain to peel and time consuming but doesn’t take away from the quality of the actual product.

I would not buy these again! They are all different shades of GRAY, not BLACK! Sadly, I can’t expect much from the 8 year old kid in China who made them. He did his best!

Just in time for summer! I used these to insulate the open window section from my portable air conditioner. That little plastic thing that fills the space let's in so much noise. Well it used to, that is. Now it's more quiet than it was before and I used the extras to insulate my AC exhaust hose so more hot air goes out of the room. Just give them a few minutes to inflate because they come vacuumed down.

Honestly, they're made by the same company I got others for $4 less, both sets I got were made in the same factory, had the same single sheet of paper instructions and same adhesive patches. These were just slightly vacuum sealed better. Both sets I got were from Dong Guan Hui Yang Polymer Technology Co. LTD Can't tell Model 2230 from Model F18

When you first open them from their vacuum seal and start removing them, you'll immediately notice a strong chemical smell. i HIGHLY recommend washing them out like the directions state, i used warm/hot water only and let them sit for about 15 minutes. Wear gloves before you ring them out otherwise your hands will smell like cheap hair dye. You can throw them in the dryer, i put 2 packs in on high heat for 30 minutes and it dried them without burning the foam. (if you have a gas dryer id adjust the time/heat) the double sided sticky squares work pretty well. like with any of this cheap foam, (i ordered the black one) the colors aren't uniform for all squares so you may have some that are more dark grey than black.

A++. If you follow the instructions you won't be like the other people complaining about this product. After opening make sure to soak in water and dry afterwards for it to fully expand.

The images look great but these arrive as very cheap foam resembling dollar store Halloween decorations. The adhesive squares provided aren’t keeping them I place and they don’t seem to be providing much sound reduction

They don't look as nice as the pictures, and the quality is really bad, they are thinner than expected and but the foam is very lightweight (not dense at all) reminds me of cheap filler material, and the adhesive stickers don't work well. Not worth the buy.

Ich musste die Rezension schreiben, da hier in den anderen Rezensionen viele leider nicht lesen können... Die Dinger kommen vakuum-verpackt an und müssen in Wasser gelegt werden. Danach bekommen die erst die eigentliche Form. Bei mir am Foto trocknen die gerade.

Definitely not soundproof for my problem.. but as acoustic panels are OK.. I can heare no more echo in my room. Anyway this are not for my problem, but the seller agreed a full refund whiteout sending the items back.. for this I am grateful 🙏

Le produit reste déformé même après 48h. Juste bon pour la poubelle.

These are not what I imagine them, but that's on me not on the product. If you are familiar with soundproof panels than I guess these are just great 😅.

Non perfetto perché almeno nel mio caso non hanno mai ripreso la forma alla perfezione dopo l’apertura dal sottovuoto, ma forse perché non avendo un’ asciugatrice non ho seguito il metodo consigliato bensì quello classico con riposo di 24 ore (io ho aspettato svariati giorni in realtà). Tutto sommato anche se alcune piccole parti sono rimaste leggermente schiacciate il risultato è soddisfacente. Ottimi invece i quadratini biadesivi inclusi.
