24 Pack Acoustic Foam Panels Sound Proof Padding,2" X 12" X 12" Sound Absorbing Dampening Foam Panels High Density Studio Foam Wedge Tiles idea for Acoustic Treatment and Wall Decoration (Arc Shaped)

First and foremost, to those saying they dont/wont expand: did you actually leave them sit for 48 hours like the instructions said to do?All panels i have, expanded perfectly fine.My only gripe is the double sided tape that comes with these. Its garbage. Go to walmart and get a pack of T pins to hang these.You'll be better off.Sound absorption is beautiful for the price.Almost a night and day difference in my audio.Follow the directions, research how to properly treat your space, and these will work perfectly. Plain and simple.Will be buying these again.

I ignored the instructions like a plebian. Don't be like me.The pads are TIGHTLY packed in plastic to roughly the size of an encyclopedia. They will come out of the plastic in a sorry state, resembling nothing like the photos.Soak the pads, or even just spray them in the shower for about a minute, so they can regain their original shape. This will happen very quickly and a trivial amount of time under water is required.The pads will need at least 24 hours to fully dry once you've done this.If you skip these steps like I did, when you stick them up on the wall, you can use a spray bottle to wet them while they're up there, but they will warp so they may not remain flat against the wall, and may even detach themselves from adhesive pads if you used them.This is also the case if you simply let them unfurl at their own pace, without water.Installing these correctly produces great results. The pads are very thick and the ribbed shape is great for capturing sound waves. I plan to buy another pack and finish covering my entire wall with these.

This product is good, i built my little studio in my closet and this had definitely been a huge help. Only thing i hated was the little stickers it brought to put it up. They don't stick well enough , so i just pin them into my wall. other than that, they are very good to use for your own studio.

Bought these for my fiancé’s home music studio. Absorbs sound and was easy to set up and the adhesive is very strong. Happy with the quality and the price!

Absorbacy who knows.. value.. not bad, depending on the actual absorption. Adhesive... absolutely garbage. I wish i had more to dislike about this product because the adhesive they give you is just so terrible and a joke and a total slap in the face the adhesive is so bad and has no tab like in the pictures so that you can seperate it and make it double sided the only way i could do it was using tweezers and im not going to waste my time doing that for each one if your reading this save yourself the trouble and order adhesive strips to come with it. if i had even one defective foam id send it all back but luckily they inflated properly with water which might i ad i looked up how to clean these kinda foam panels and it says soaking them will increase degradation over time alot so having to soak these to get a proper shape in some is probably damaging them and shortening their lifespan.

This was THE biggest waste of time dealing with this product. The adhesive is a huge FAIL. Very frustrating. The adhesive sticks to the wall but NOT the foam panels. In fact, after trying 2 other adhesives - the only option is to screw the panels into a wall. Do not waste your time on this product.

OK, was skeptical because of some negative reviews but don't be swayed. These work FANTASTIC! The key is to not rely on just leaving them out sitting in your room and they will miraculously be perfect. It takes some effort! I bought 48 of them so it was a couple days process. YOU HAVE TO SOAK THEM IN WATER! They are super compressed when you get them but if you fill your sink with water and then soak each one and wring them out REALLY GOOD, then set them outside in the sun they dry pretty quick. You will have to flip them and maybe even use a blow dryer. But they then will be perfect. I didn't care about the two sided tape as I was planning on using Command Strips anyway. Saved the tape in the junk drawer for other projects.

Great for the price, do the water soaking method but expect to dry them for a long time with a hair drier, if you air dry it will take a week or so to dry out (it is currently winter and only 70ish degrees in the house)
