48 Pack Self-Adhesive Acoustic Panels 1 X 12 X 12 Inches - Acoustic Foam - Studio Foam Wedges - High Density Panels - Soundproof Wedges - Black/Green

EDIT*** the seller has reach out and rectified the situation, so I am happy with the product/order.I ordered two packs of this... which was too much, but one wasn't enough. Good thing I got two, because about 15 of them *from each pack* where not up to par for quality. They were either cut very thin or never fully expanded, and others were proper thickness but had "tags" at the peaks about a half-inch tall. Sound dampening was as expected. Had to use a crap-ton of adhesive spray to get them to stick to the wall. The sticky squares that Amazon recommends you buy with them stick to the wall, but not the foam, so don't buy those. Have heard mixed reviews with velcro-like products, didn't try that method. Probably would go with a different supplier if I order this again in the future.

Yes, they are inexpensive sound dampening foam squares. Don't buy if you genuinely need mid- to professional sound dampening quality. I didn't need much, and was more interested in developing a "professional-looking" dark backdrop. They work great for creating that professional-looking environment! However, as the other reviewers tend to mention, the foam is too porous for tape of any kind to stick to it.I put these on a sheet rock type of wall. I used inexpensive duct tape (painter's tape would probably be better) just to get the panels in the best positon, then I used my heavy duty staple gun to secure them to the wall ... then went over the staples with a black sharpie (matte paint, etc. will work better). My reasoning was that the staple holes will be very tiny and easily mudded or spackled over, and that spray, spread, or caulk-like adhesive would cause a much larger, future hassle to remove ... if not remove the paint/primer and possibly the top paper layer of the sheet rock.Just thinking about the value of the room/wall(s) and the amount of future labor if I ever need to take them down.They do exactly what I need from them, and if you don't need mid- to professional-level sound dampening, these work great. You "could" hang carpet on the wall, but that's a heavy solution (as far as damage to the wall), more expensive, and not as easy to find the right color/pattern for the aesthetic if you're making videos.Hope this helps.

Ok. Let me start by saying these arent top studio quality acoustc pannels, those will set you back a lot more than these. HOWEVER, for the price and the quantity you're actually getting a good deal out of this. There's some reviews saying these didn't expand or that they came defective, and as someone who's bought this product twice, I can confirm that a handful indeed do come thinner, but out out of the 2 times ive bought this product, only the second batch I ordered had defective panels, and it was only 4 or them, I counted. As for the foam not growing to its proper size, I didnt have any issues with that. I put then in a spare room for a few days and let them sit there untouched and they expanded just fine. Addressing the thickness of the foam, I actually measured it and there are 3cm from the base of the foam to the top of the wedge, which is about 1 inch, exactly as advertised (bear in mind im excluding the defective units from this claim, as these arent even 1cm thick). The panels also arent all the same size, although most do reach 31cm each side, which is the equivalent of 12in. So to restate my point, this product has great value for the price. The thickness of the foam is as advertised (1 inch or 3cm), the panels, although very slightly varying in their dimensions, are generally 12x12in (or 31x31cm), the faulty units are few and can be counted on a single hand, and they do indeed expand (WITH TIME) to their advertised size.I want to add a section to advise those who cannot get these to stick on their walls. FIrst off, any double sided adhesive tape or command strips will not stick. These will stick to the wall just fine, but the foam is too porous and will come off extremely fast, lets say, 10-15 minutes from the time you stuck the panels to the wall. Instead, I recommend using a heavy duty constructive adhesive, such as DynaGrip (I tried several brands, and even though they mostly all work the same, I feel like this ones a tad more sturdier than its alternatives), which comes both in a squeezing tube and and a tbe that requires a pump gun or whatever theyre called. I add glue in dollops, in approx. 1x1x1cm size, 3 times on each side of the panel, ergo 4 on the corners and 4 in the spaces between the corners (so 8 dollops of adhesive) as well as the middle, Im sure you could get away with just the corners and the centre, but I found that this way the panels will not fall even if you lean your entire body on them (I tested this, and my cat also jumped on one and the panel didnt even budge, and she is one hell of a chonker). With the adhesive on the foam you can spread it with your finger or a stick or a paint knife, or anything really, and then just stick it to the wall. After that just press the panel on each of the zones in which you put glue (not for a long time, just give each zone a quick press and thats it, do it twice if you want to be cautious). The adhesive sticks on cement, wood, drywall, and even on metal. It will even work if you want to stick your panels to the roof, no problem with that, just make sure you give the roof panels a hard squeeze to make sure gravity doesnt tear it off while its drying.If youre looking to make a home studio or just fix a terribly sounding room, this is an awesome deal that wont break your bank. They actually d help the sound. REMEMEMBER, these will NOT soundproof your room, these will only treat the echo you can hear inside a room. I recommend complimenting these panels with carpets and rugs, as well as corner bass absorber blocks.Im uploading images of the panels individually, how they look hung up on a wall, what the defective units look like, the measured thickness of the foam, the adhesive I used to hand mine up, and the way I spread the adhesive for anyone that requires help with that. Also, I've already had these panels on my walls and roof for 4 weeks, still holding up perfectly.4 stars out of 5, the missing star is due to the defective units.

For starters I want to say I gave this product the benefit of the doubt until it was undeniable that this is a waste of money.Maybe for you it will be different but for me this wasn’t a good purchase at all. I bought 5 packs in total I believe each pack had about 50 something in them and I glued every.single.one in my room and there’s basically no difference I can still hear normal volume talking in my room. They did not do what they was supposed to do which is apparently soundproof the space my room is not soundproof at allMy room now just has the slightest muffle effect to it put your hand and inch or so over your mouth and talk….that’s how it sounds so again basically no difference and I spent good money on these panels most of my walls are covered in the panels I even double layered some and even triple layered my door but it makes no difference I would recommend getting panels from another merchant

Let me first say that this is super easy to set up, it performs way better than expected, they look amazing, the cost is way less than expected, they're perfect size, and they weigh nothing even when they were all together in the box.I've been told for years that sound panels make a huge difference in sound quality but didn't realize how much of a difference until now. While recording, streaming and chatting with others, it's made my microphone quality jump through the roof. Setup took a few tries to make it sound perfect but a few youtube tutorials helped me with that.Works perfect!

لم ياتى بلاصق فى الخلف

First off, would like to point out the obvious that you should not buy these as an attempt to soundproof a room, and that the panels come with clear instructions on the fact you need to leave them air out prior to putting them up.That being said, I left my set air out for about 48 hours and they rose perfectly.There’s not really much you can say about acoustic foam. It’ll dampen sound well enough, providing you know where the zones are in which sound is most likely to bounce around etc.Bonus that it’s purple & black I guess too!
