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.

Very simple to install, make sure you measure at least twice. Sticks to walls great, if doing ceiling, use liquid nails, couple dabs. There was one panel that the corner was chipped, company should use protectors for the corners when shipping. Other than that, it's worth it. Been a week now and holding up.

Looks great and works as intended. However, likely due to the packaging, more than half of the panels did not peel off the backing paper easily, and the adhesive remained stuck to the paper instead. It took some extra ingenuity and effort to resolve the issue. If this packaging problem were fixed, the product would easily deserve a 5-star rating.

The panels worked flawlessly for me. First off and most importantly they’re very fireproof as you can see from my video. Not even a direct flame form a torch can get it to light on fire. The 24 I received was enough to reduce the noice from my cello by 1.6 decibels, and that’s considerably good! The tone sounds way better as well with that slight reduction in reverb. The panels stuck very will with the full back adhesive vs the small stickers you’ll see on the competitors. Also them being easy to cut and as a bonus. I was able to use small trimmings from pieces I cut to fill and small gaps between panels. The gaps were there due to me rushing installations. All in all I strongly recommend this product. The cost is perfect for what you get.

I have bought these twice, and the second set developed a terrible mildew smell within a few months just like other reviews have mentioned. I had to take those down and trash them. Both sets were effective, but I used them for acoustic dampening, not soundproofing. First set went in a giant HVAC unit closet that holds a heat pump, and it dampened the sound. I used the adhesive backing and stuck these to the exposed back of drywall, they stick great even being exposed to a range of hot and cold temps. Second set went in a corner of my bedroom where the HVAC heat pump noise echoed. It dampened the echo. I did NOT use the sticky side on the drywall, I was able to use a single nail in the corner of each panel to hold them in place. They did great to cut down the echo, but this was the set that started to smell musty after a few months. I live in the high desert and it's never above 35% humidity indoors, so. This is a problem with the product and how it's packaged and container shipped. It's hit or miss, you won't know for a couple of months if you have a problem with he mold and mildew growing in the tiles. So. If you are putting these up somewhere not in your living space with the understanding these are sound and echo dampening, not sound proofing, go for it. If you want it for your bedroom, find something else that won't be surprisingly smelly in a few months.

Reduced the noise of my built in refrigerator by 75% by placing product on some of the inner cabinet (which was acting like a speaker box.) You only have to cover part of the walls to make it work. This is for sound absorption, not sound proofing. The surface needs to be exposed directly to the sound or noise. Very sturdy but easy to cut to any size with a razor knife. As others have warned, fantastic glue, but it takes precision & patience to tease off the paper backing without removing the glue layer. I found bright light & the tip of a razor knife worked best to separate the paper from the glue. Easy enough to nail or screw in place if you like. Some complained the boards are too thin, but thickness is no issue, since absorption & dispersion takes place only on the surface. I think the bad reviews I’ve seen here are folks trying to soundproof a room (to sound outside) or place the panels behind curtains, etc. They won’t work like that. Would be a great treatment for a music studio or home theatre. I tried several other products before finding this one- it’s a winner- highly recommended for the right application.

Not exactly as advertised. I received 1 inch thick compared to 2 inches as shown.

Se adhiere fácilmente a la pared, ideal para contener el ruido, el producto llegó en la fecha indicada y en buenas condiciones 👍

Very good

I bought these to add some sound proofing to my music room and they do a fantastic job. I think I purchased about 3 bundles of 50 to do the majority of two walls. I put them up on the styrofoam sheets that are up against the concrete foundation so they help with the temperature downstairs as well. At first I tried double sided tape squares but they didn't stay up so I hot glue gunned them on and they won't come off unless I pry them off if I ever move. The pattern looks fantastic and the room now has a studio quality to it that impresses anyone who comes by to jam or visits and gets a tour. Highly recommend this product.

Produto de baixa qualidade. Muito ruim mesmo
