They arrived vacuum packed with instructions to either soak them and leave to dry or leave them to air for 24-48 hours and they would take shape.I did the latter and for the most part the tiles did. And by that I mean most of the tile took its shape but on all of them, the bottom 2cm remained flat.Thankfully what I needed them for was to be inside a cupboard to soak up some of the noise from a computer fan. And for that job the fact 2cm strip was flat didn't affect me. But I would not be happy if the intended use was visible to people.In addition, I tried using 3M spray adhesive on the rear to stick them to the cupboard door and wall but they'd just fall off after a few hours. It seems no matter how much I sprayed them, they didn't stick. In the end I used velcro strips I had handy which seemed to do the job.In fairness, the tiles do seem to have absorbed the noise pretty well so that's good. As I said, visually it's a little annoying and the tiles aren't very thick. So I doubt they would absorb a lot of sound.

the tiles would not stick to my double sided tape. They have not helped in reducing noise from upstairs stereo system, still able to hear music from stereo .

I can say that these work. Because 2 years ago I bought these products for sound insulation. I was not satisfied at all and threw it all away. Then I bought it again and again I am not satisfied. Finally, I covered my wall with this brand that I was satisfied with. But I forgot the door. The door of my room is very thin so a lot of noise disperses into the house. It is noisy especially at night when I am playing games and talking to my friends. In order not to disturb anyone, the decorative, inexpensive and definitive solution is to use these sponges.I think 3-4 days ago I covered my door wonderfully with these 12 pieces. I applied the vertical + side + upright + side combination to be decorative. I would also recommend using crosswise, it looks cool.There is a gap of 1-2CM under my door, there are gaps of half CM on the edges of the door. So I coated these sponges over those gaps. No problem, my door opens and closes wonderfully. Because these sponges are soft and useful. I tested the sound going in. I turned on music with 30% on my 2+1 Sound System. I recorded this music by fixing the phone to the living room. Then I did the same test again after using these sponges. I can definitely say that the sound is reduced by 60-70%.Don't make mistakes like me in my pasting. In my first experience, I used very bad and cheap stickers. But the best method; It is to stick double-sided square tape to the four corners of the sponge. The square double-sided tape of the 3MM brand is 100% compatible with these sponges and is of very high quality. It is very good to clean and disassemble. It's a great solution especially if you want to wash these sponges occasionally. Because I can wash sponges in the washing machine at 20 degrees to 30 minutes.

Unpacked and left for a week to expand before using. Some panels are thicker than others and some are not square. They work but I expected better

The tiles arrive in a very tight vacuum seal, which have probably been sealed for a long time. This causes some of the tiles to not return to full size despite being left out for several days. 4/12 did not return to full size, or had been partially crimped by the vacuum seal.However, the customer service was excellent and they were quick to resolve my issues, and the replacement items despite suffering the same issue did leave me with the full set of 12 functional tiles that I had purchased.The item arrived quickly, and do come with instructions and waiting times. I would not recommend the 3m adhesive pads amazon advises you to buy, as they will just fall off the wall. Instead buy some mdf and some spray adhesive and fix them to the wall via command strips or similar.The finished product looks good, and from what I can tell have been decently successful in improving the sound quality in the room.

Ordered these foam acoustic panels before Christmas and have finally had time to install and test them in our karaoke room. Cheap, and does the trick in minimising sound travelling from one room to the next. I will be buying more to increase the effect of these sound absorbing panels. Thanks!

Brought these for my garage to minimize the sounds created in that environment. They don't look half decent with the triangle shaped and we're surprisingly easy to stick on using double sided tape. They come in a very tight small vacuum sealed pack so do need to be opened and left out for a few days to allow them to return to their original sizes.

This product was absolutely excellent,it created a snug affect to my room and also made my room more sound proof than ever!.These were also very easy to apply and was done within minutes of following the step by step manual included in the packaging,10/10 would recommend
