24 Pack Wedges Acoustic Foam 30x30x2.5cm Black Sound Proof Panels Fire-resistant Soundproof foam High Density Sound Panels for Recording Studio and Office...

One side of the foam is smashed and doesn't does fluff up. Zero noise cancelling effect and it needs separate adhesive too.

Bad quality

There’s nothing special about the look of these acoustic panels. The magic is in the thickness. Each of the six panels are two inches thick and 12”x12” has always been my go-to when sound treating my space. They provide great sound reduction with their pyramid design. The 3D-look is really cool, too. Peel off the protective backing to reveal a good quality adhesive back. I usually add some staples but I don’t think it’s entirely necessary. Also zero smell. Which is a plus when installing in a small space like a recording booth. The black color goes with any decor and adds a bit of intrigue.

Better than most for vocal and decent price when I got them, Imma invest in a bigger pack next time, the folds in the middle should break up some unwanted reverb, mite want to start here like myself then add panels and traps later

Absolutely happy about these foam for my studio. I had previously bought the pyramid type for a booth and needed to get more for the walls. I really like the style of these and when their direction is alternated it looks super cool on the wall. They arrived vacuum sealed, so I left them out for a day to get back their form, although they started to form back almost right away. One thing I did notice was that they had a very strong chemical smell, I had to open the window for air and turned my fan on and it disparate after a while. I had used double sided tape to hang them and later on when I came back into the room they were all on the floor. However I think that tape isn’t the best quality. I will find an alternative. Really great quality foam and easy to use.

This is the BETTER quality acoustic foam out of all the options found on the site. The asking price is well worth it when you realize these are genuinely the full thickness of 2", and even better, the foam itself is extremely thick but very porous, with the pyramid shapes leading into an additional 3/4-1" of foam. Those things combined makes it far more useful than the thinner, and usually cheaper, options. When it comes to audio, until you reach that audiophile level of diminishing returns, you OFTEN get what you pay for and these are no different. Quality sound treatment, looks professional especially in a studio black and modern style room, and genuinely couldn't be easier to install with the adhesive, which so far, has held everything on very well.

I was having some echo issues with an odd corner in our rec-room and the TV surround sound system. These panels solved the problem and greatly improved the theatre sound in the room. They look decent, and with the self-stick backside, they were easy to apply. These are acoustic tiles and helped to reduce the echoes. If you are looking for complete soundproofing, these are not the right product for that situation. I'm very satisfied with the quality and resulting sound with the ease of application.
