18 Pack Acoustic Panels-12"X12"X 0.4"Soundproof Wall Panels, White Sound Absorbing Panel,High-Density Sound Dampening Panels Acoustic Treatment For Home Studio

50 Pack Acoustic Foam Panels,2"X 12" X 12." I wanted to wait until I purchased my second set to do this review so that it would be honest and accurate.To be clear, these are not for sound proofing...they are for sound absorption just like a sponge absorbing water. They absorb room reflections but do not block sound. They're foam. One example is for vocals to keep the reverb in the room from coming into the mic. This will not keep noise like cars passing by, helicopters flying above, HVAC, or other noise from coming in hence, they will not block sound and soundproof your area. This is something that you as the consumer need to understand and accept BEFORE you purchase these panels. As sound absorption panels, they are good quality panels and work great!Also, to be clear, I am in no way telling, suggesting, or recommending anyone to NOT purchase these panels. They are good quality panels and I have had no issues with them!First thing to know that it clearly says that the adhesive tape does not come with the panels...you have to purchase your own. These are NOT self-adhesive!Second, when using the adhesive tape like 3m, you will need some additional adhesive like Gorilla Glue as foam doesn't always stick to the adhesive tape or the wall.Third, be patient! The best method is to let them set out for at least three days. The first two days is for the "smell" to air out while getting air in. The third day is an extra measure to examine them to see if any forming needs to be done.Pic 1: When then arrived and after I took the package out of the Amazon Box.Pic 2: When I took them out of the main wrapping. There are two vacuum sealed packs.Pic 3: When I took them out of the main wrapping. Since it's now unsealed, air started coming in and they already started expanding. Note: They expand quickly so prepare to get them out of the back quick!Pic 4: What they looked like 5 minutes later. Some expanded in full and some didn't and are deformed. There are two to each "stack".Pic 5: One of the "stacks" that was still somewhat compressed and deformed.Pic 6: After I pulled apart the stack that was still somewhat compressed. One panel.Pic 7. The other panel. Notice on both panel the triangles are deformed.Pic 8: Me beginning to pull the triangles gently.Pic 9: Me fully and gently pulling the triangles gently. As you can see, it's already getting it's form back. For the panels that are deformed, gently pulling the foam to get it to form helps get more air in and they will get their form quicker! This part takes patience! Those that said the panels would not take shape or stay deformed are not doing this to help shape the panels!Pic 10: All 50 Panels laid out and getting air All of this was done within one hour. They still need air out to completely form. Although the directions state 24 hours, it's better to wait 3 days. On my first set, I sprayed some Febreze to further take out the smell and will do the same to these. This does not take away their absorption properties.

Before purchasing, I'd read about how strong the adhesive is, and how difficult it is to remove. A few months ago, I rearranged my home office. I tried using heat to soften the glue, for easy removal. Nope. It just curled up, so i left it alone. On 5/16/25 (a few weeks ago), my home was destroyed by an EF4 in London, KY. While going through the debris, I found a panel, still attached to sheetrock. It gave me a chuckle, and I vowed to write a review.

I bought 2 different brands of these, these are the best. There was 1 tile that was not like the rest. It's a different color and looks different. Additionally, they don't come with tape and they are hard to tape to a wall. I'm not sure what tape is recommended by I had to staple these to the wall.

They are great. Out of the package they bag an to expand immediately. I was a little worried that some were too smashed but they expanded perfectly. They are the full 2”s and they also stiffen up good.The first 3 pics are after 24hrs. The last 2 are are right after opening.My only issue was that they are extra black and the ridges are smaller than my other/older foam panels from the foam factory. The last pic shows the difference with other panels.They do exactly what they are supposed to which is absorb reflections and frequencies bouncing around the room.I would definitely recommend and purchase again.

this product was great for sound proofing but when we moved they wold NOT come off rips off the paint i don't reccomend these.

BUYER BEWARE! Well, this is an unfortunate situation. I opened up the panels and started using them to help with a recording booth. But when I opened up the last package of the 50, 19 of them were defective and warped on one or more sides. I let them air out for a few days, nothing. I listened to their insert to try the other recommendations to get them to take their normal shape. Nothing. Their product support page? Their email is deactivated and so is their business phone number! So... whatever you do, if you buy from this company. Beware that there are going to be a large number of defective pieces that you will be stuck with having to use because you can't contact the business to get product support for deformed and defective pieces. I'm surprised amazon let's them sell with no accurate business information to resolve issues like this... and now I'm stuck needing 19 more panels...

These turned out to be pretty cool . Easy to work with. When peeling the back the sticky part peels up with it sometimes. Not a big deal . Just like pushing your cuticle back. You peel the back a little bit the sticker might come up too when it does you just take your fingernail and push it back that's it. Once you push the back you can peel off the whole back of it and you're good to go. Most of the time you don't have to even deal with it because there's going to be one corner of the peel off that's a little bit longer so you can peel off the back super easy. I was putting them on the ceiling and it's a no-brainer. Start out square put the next piece up against the last piece nice and square and you're good next thing you know you've stuck 72 of them on your ceiling. And it really really works sound deadening material spot on.

I have a budget home theater room and used the foam panels to reduce noise reflection, 'echoes', and to improve sound clarity. The adhesive works great, to date non of the panels have fallen. Anyone purchasing, if budget allows, should buy the 2 inch or thicker. But, these works well for me.
