GUERRI 36 Pack Sound Proof Foam Panels - 12 x 12 x 2 Inches Wedges Sound Proofing Padding for Walls and Ceiling, Fire-proof Studio Soundproofing Wall Tiles(Black)

Read a lot of reviews on numerous/similar products. This one mentioned a horrible smell that lasted days after opening the package. Mine did smell a bit when I took them out, but it went away after about 10-15m.The sound absorption for what it is and the price is pretty decent. Had a very echoey room. After putting up all 36, there is virtually no echo to be had.Most fluffed up to 2" thickness right away, but some did not. I put all of the panels in the dryer on low for about five minutes and they all puffed up to the expected thickness. Definitely recommend for someone trying to lower echo/etc by way of small panels.

Work great for green screen backgrounds and sound quality

I have ordered 2 sets so far as the first set I received were perfect. Let them sit out for 24-48 hours and they formed right up. Then I ordered another set and did the same thing but that set was bad.. how they were cut, the triangles did not poof out, got a replacement set and same story.. had to take the good ones from both sets to have a perfect set. Just beware. Yes, they smell REALLY bad at first. The scent does go away and everything is fine.

These work really well and I really like how they're a different color other than black. They really brighten up my studio.

Primero se veian asi y espere 24 hrs y algunas partes seguian comprimidas, pero las remoje en agua y quedaron hinchaditas excelentes. Las metí al cuarto donde grabaré, y no estan ni distribuidas y se quito la reverberacion y eco. En verdad muy buenas en cuanto a color diria que es como un lila rosado muy bonito.
