24 Acoustic Panels Wedge Sound Absorbing Acoustic Treatment Tiles 25x25x5cm Studio Noise Cancellation 26kg/m3 High Density Acoustical Walls Dampening Foam Fire Retardant 1134 WHITE

Work very well, most reasonable option on Amazon currently

The product’s quality is excellent. It’s perfect for acoustic purposes, but not mainly for sound proofing. The delivery was faster than I expected. 👍

It looks sharp and attractive. Also works very well at absorbing sound. The delivery was also quick. I used water on them and they puffed up quickly ( had to wait 24 hours to dry).

Looks good. Not sure yet if its effective in soundproofing the room. Includes double sided tape that isn't that effective. Panels keep on falling

The photos look fine of course. The reality is different. The tiles turned a custard yellow in just few days. Aiming to reduce the noise in our bedroom we now wake up the last two nights from tiles falling off the wall. If ever you decide to buy, do take black. And do yourself a huge favor: get proper double sided glue strip from 3M not from some unknown Chinese.

Some pieces were yellow

Used product to reduce feedback loop. Placed foam on concrete wall with speakers facing the foam. Works for the most part. Would be even better if I were in a position to cover all the walls and ceilings with foam and floors with carpet.

Really happy w the product, came well packed and expanded properly in less than a day . Just follow the instructions.
