Acoustic Foam Panels - 9.8 x 9.8 x 2 Inches Pyramid Sound Proof Foam Panels Fire Resistant Soundproof Wall Panels Studio Foam for Wall and Ceiling Acoustic Treatment (24 Pack Green)…

Work great for green screen backgrounds and sound quality

Clearly inferior to actual acoustic panels. Just another repackages Chinese garbage haha

Yes, they absorb some sound. I got them to try to drown out my son’s video game rage. But it’s harder than heck to get these to stick with anything. So even if they are up and blocking noise, they’re also falling off too. Definitely get a lot for your money though!

These tiles, once expanded, have excellent sound absorbing quality, and the color contrasts well with the rest of our music room. There was no adhesive included, so we had to buy our own.

They are not bad quality, however you can not place them unless you have double-sided tape or spray glue as stated in package. It is disappointing because this will damage my wall in the long run, the ones u get don't work AT ALL

Great color bring that great balance to the studio room. Good for a noise cancellation. That he’s is not that good but you can get the spray spray and they stick on the wall to speak on anything. Great to have for studio and still need a quiet place to record

I like the visual appeal of the green pyramid 3D acoustic design foam panels. The panels are going to provide a quieter household when I stick these on the back of the bedroom hollow doors of my kids rooms. Im hopiing it will providesome sound control and absorb the sounds a bit from a late night gamer teenager, a chatty teenager who facetimes with her friends, and the other obsessed with you tubers playing minecraft. The sound of these 3 echoing down the hall will be muffled & tolerated easier once I'm finished with my stop the noise project! Im happy that they are non toxic & flame retardant as well since I'm coating the backs of the kids doors, they really need to be.*updating with more pics & sound progress of project.
