DEKIRU Sound Proof Padding Foam Panels, 2" X 12" X 12" Acoustic Panel Studio Foam Pyramid Tiles Sound Absorbing Dampening Foam Panels Wall Soundproofing Treatment with tapes (24 PACK, Black)

Hello! So I bought 3 sets of 24 of the 12x12x2 foam squares with the pyramid shape. And I must say for the money the foam is pretty solid in the density and looks overall. I did order all black squares and some do look slightly different shades then others. But once up not noticeable however my room is a little darker. For the money and the amount you get mixed with quality id rate 10/10. I was looking at 'Arrow zoom' foam before hand but the budget with other room upgrades and yada yada I had to cut corners.Now... before I blast away this is just a side note more then a negative comment. I tend to read the reviews and watch videos on things before I buy them. Especially things like this. Alot was said about the 3M adhesive squares that come with the foam tiles such as they dont stick well. So I bought an additional 240 3M squares in bulk through Amazon also. After getting everything un-packaged and waited two days to maximize the un-compression of the foam I went at it. I stuck nine 3M (1.5"x1.5") 3M squares on the back of each one. And still they begun to fall after an hour being up. not all but some. Another thing to note is that I Live in Arizona and it is summer so my walls are a little warm as I dont run my ac all day while at work. So after a little more investigating I found the solution! T-PINS!!!! You can get a rather large pack at walmart. I bought 3 boxes and pinned 5 pins on each square. I pinned each one down like a 5 side dice.After about a 3 weeks to a month of using I can honestly say I love these foam panels. I ended up almost filling op one whole wall in my bedroom and an additional 4 foot by 2 foot section on another wall in the same room. I can definitely tell a difference within my room elimination unwanted echo. It helps with secondary sound reflections. I also bought some blackout curtains by PONY and in black. And the combination covering both windows in my room with said curtains and the foam aligned as described kills it! Ill post pictures soon to ease any doubts. And hey if you dont agree with me if you buy them....... Then return em! Cheers!

I didn't even try to use the included tape due to reading others reviews and I understand why after seeing them, they're very bad. Otherwise the only other note I have is that they can be very stinky so make sure that you have good ventilation for the first couple of days because at least for me they smell real bad

Not sure how the product works yet, could not install as it did not come with 3m adhesive as advertised. Would appreciate the full package I paid for.

Bought these so I cant hear white trash outside and so that noone will be bothered by my bass, I work from home so 24/7 basically I have music going with "one crazy stereo" in my living room 7.2 surround on 2x 12" long throw expensive subs (it is awesome), problem being is that low resonance like that carries, I can hear this turned up amps on 30% at my Mailbox @ 110 feet away from the door, after doing the entire wall I can clearly hear a difference in same songs and also while getting my mail, I'm a conservative so I dont like to go around being a nuisance to others however I like my music loud kinda and even when not loud the lower sub frequencies carry bad especially on long throw subs, and thats just after 1 full wall, however keeping these things hanging are a challenge the stickers they give are "terrible" and thats an understatement, they send you like 200 of these utterly useless stickers, I tried literally putting up an entire row and it wouldnt stick with even residual gel left over and then without music on yet, they are that bad...so currently still looking for a way to properly stick these things on the walls, the product works great but the adhesive is just terrible, 3M has come a long ways but lets be real the technology has not gotten that great lol you can tell where they saved money at, other than that I gave it 4 stars as once I do this entire computer room, living room and work room along with part of my kitchen, on a side note it also helps as an insulator if used in windows behind mirror tint around the house which allows my Air Conditioner to take more breaks ive noticed, also temperatures on average have dropped in the general area after doing it by 8F average, its not a gamechanger but just keep it in mind when hanging them q=>

Purchased the 24 pack, came with plenty of 3M adhesive tape. I've only had them for a few weeks, but so far they do the job (reducing echo from the walls) and I'll be buying another pack in the near future to complete the room. Good product.

Not a good value. These do very little to dampen noise. It was like I did nothing. False advertisement for sound dampening. The mounting stickers stick okay but are horrible to use. The backing takes tremendous effort to remove. Looks nice after installation but that is all it does. Changes to look of the wall or door but does nothing to dampen sounds. With all the gaps sealed around the door and fully covered, the sound that comes through is clear and understandable whether someone is talking on the other side or a tv playing at level 10 out of 100 setting. Not worth buying or using. Find something else.

So far so good. It came well packaged. So well that I was nervous it wouldn't expand back out. Photo one is out of the bag and photo 2 is after roughly 40 minutes. A few aren't expanding as much as I'd hoped but I'm giving it a day or so before I actually place them up on the wall. Photo 3 is how it was wrapped for reference. Fingers crossed they'll work and I won't need to hear my husband yelling at his game!

The packaging kind of ruins some of the foam. The smell is unbearable. My wife says my room smells like fish now. I think its more of a powerful chemical smell. Why?!?! Disgusting!
