ArrowzoomNew 12 Pack of (25 X 25 X 5cm) Pyramid Acoustic Foam Studio Absorbing Tiles Pads Wall Panels Black 1034

Products arrived quickly and well packed. The package is vacuum sealed so the products look smaller at first, but lay each tile out for 24hrs and they “grow” into their form. They are foam so are really light, therefore easy to put on the wall without the need for any tools...just some good quality adhesive strips. They work well in my “home office” to reduce the echo on video calls, so well worth it.You will need more than 1 pack if you want more sound dampening but this will depend on your personal needs.All in all, very happy with the product!

So these are not huge by the way. You have to soak them up in water then let th dry before you fix them on a wall. Although I did not cover the entire wall with them but it didn't seem they did anything at all to keep down or isolate any sound.

For all people saying it doesn't prevent sound for leaving my room, doesn't block sound, etc.. please do inform yourselves about the purpose of these foams, don't be ignorant and give 1 star reviews for something that this product it is not supposed to do. For me they work, they look nice and they are decently priced.

Exactly 6 pieces are not in a perfect shape even after keeping it for more than 24 hours to recover and take the normal shape

I spread 24 pieces around my room (3x3m), it reduced the echo a little bit.But i think I should cover the room with it?? No thanks

The acoustic foam arrives in a flat air compressed package but it will only take more or less 24 hours for the foam to fully regain its shape. It's well manufactured and will surely last for a while. It's also easy to install virtually anywhere you wanted it to as long as you use the proper mounting tapes.The price reflects its quality and I am reasonably satisfied.

The delivery was fast, however I bought 2 packs and the sound impact was minimal at best, it is also a pain to stick these up as double sided tape keeps causing them to fall off the wall. I’d recommend just getting a door stopper instead.

if anyone buying this one just do this: when you open the product you will see that foams are too thin because of tight packing, before you tape it to wall wash it with warm water not too warm, than put it aside for 2 or 3 hour under a/c, after that you will notice it become much bigger and foam will get it shape, so just wash it before putting on your home or studio wall + I used Torix 3 Meter Magic sided tape it works perfect for my home wall. Thanks

I'd ordered a larger number of acoustic pads before, and they all formed-out perfectly plump and square without the use of water - just 48-72 hours of open air decompression. The edges were straight, corners crisp, and the material easy to work with. I use these panels as to reduce mid/high frequency glare/bounceback at my sound desk - premounted on coroplast backings for easier moving/mounting. This last order of 12 black came perfectly packed and fast - as expected - but the panels themselves didn't decompress nearly as well as the original batch. I ended up using the water method, and patience, and the end result was plump panels - fairly straight edges - but the corners were mis-shaped and somewhat skewed, therefore making seamless installation highly problematic and tedious (needed drops of Gorilla Glue to mend each corner together so they'd look "all intact".Aaron (Seller/Rep) was quick to ask exactly what was happening with this latest purchase given that my first order came out great. I'd originally given these pads a 3 star rating as to compensate for the former 5 star rating I'd given my first order a couple months ago; because this most recent order was indeed "inconsistent" to my prior "foam purchase expectations". Aaron was very helpful and we've resolved the issue - all I can say is yes, these may "just be foam", but the Seller went above and beyond what I'd consider to be "customer satisfaction & follow-up" that I can state for sure - with confidence - buying from Arrowzoom is a solid experience with professional end-buyer satisfaction their No.1 goal.I'll be back for more foam when the need arises.Thank you Aaron & Arrowzoom!!

The foam is fine, it’s not heavy-duty & it’s fairly thin but for the price you can’t ask for much more. Don’t be alarmed about the packaging, when you pull them out they will be flatter to start - run them under a shower until they’re soaked in, wring them out & lay them out to dry somewhere (I laid them flat on top of some garbage bags on my spare-room bed, & flipped them after 24 hrs, then waited another 24 as they were still a bit damp) After 48 they’ll be ready to go. (Blow-dry them if you want to put them up the same day)Don’t rely on the 3M peel-&-stick squares that come with it, as they are absolutely useless, & even if they were effective there are not nearly enough of them to accommodate each square. So once you make your order, head out & grab a roll of strong double-sided tape & have it waiting for when your foam arrives (or grab it while your squares are drying). Then line your dry foam squares with it, & stick away.They will dampen the reverb in your studio/room & take away some of the wetness for better sound quality going in, but they won’t keep sound from “leaving” your studio as they’re not heavy-duty (for instance if you have a partner/kids sleeping a couple rooms over etc) for that you’ll want to look into heavier foam, door-sealant tape etc.Overall you’re getting what you pay for - decently-priced for decent quality.

Our house is a bit bare (less soft surfaces) and sound travels easily with the layout. We purchased a pack to try.1. When you take it out of the package, you will need to lay them out and allow them to reform and expand. For us, it took 2-3 days (which is fine!) They should spring back into shape, this may take longer depending on what you receive.2. We didn't glue/stick/mount them onto any surface. We hid them behind canvas pieces and mounted TV's. We found this did a pretty good job at absorbing sound.Do we recommend this? YES!We are planning on purchasing more to add around the house, especially in rooms (while not used often) may need more sound protection when used. We found it was easy to 'hide' them around the house.Tips for hiding: behind canvas' work really well, behind TV's, hard surface furniture with a gap underneath, between curtain panels.

Heads up for anyone who's trying to muffle the sound a bit in a medium-sized bedroom, 12 squares of 25cm2 aren't enough to change the echo nor the muffling in my room. Now for the benefit of the doubt, that's my fault for not getting more. I purchased these to 1)experiment a bit with acoustic foam, and 2) make my room quieter while trying to do school work from home.My room is not quieter, and I have too few pieces to experiment with, AND 3 of my pieces didn't fully decompress to the size they were supposed to even after following all the instructions to the letter. 4 stars because most of my negative criticisms are more my fault than the companies. Still, you gotta fix that decompression problem because a quarter of my panelling isn't even at your standards.

This is my second set of 12.Please follow instructions before leaving a review. They expand a lot even after only a couple hours.I'm using it to get rid of some echo in my PC Room, has done a decent job so far, will update with pictures once its all 24 are up.Really easy to install, I've been using Command Poster strips to hang them up I've had the first 12 up for almost a month without any of them falling.
