Acoustic Panels 12-Pack Soundproof Wall Panels 12''X12''X0.4'' Sound Panels High Density Sound Dampening Panels - [Denim Blue Square]

These tiles were firm and 99% as described. They were closer to 11.5/11.75 inches vs 12 inches. I haven’t listened to any music yet to see if they make a difference. I used 3M Velcro to adhere them to the wall. Install was easy. They look decent enough.

The one big draw back is that this may be the only company that comes with no glue in the tiles! Same price than the others that are made with the same quality and come with glues backs. Having tiles with glue backs will save you lots of time and extra money buying glue. Don't waste your money on this ones with no glue!

Better for looks than sound dampening, IMO. I think they’re just too thin to be really useful for that. It’s better than nothing and much more cost effective than the large foam or installing a fluted wall. So I’m a fan.

Some panels thickness is not uniform and can be seen while the spot lights ON, Daytime its not that aggravating and seems okish ! Its pricy from the quality stand point and maybe once these give up eye more eye soar will be taking them down and try some better tiles or other stuff. The sound absorbing capacity or reducing echo is almost negligible and would not grade it against anything claimed on Sound matter. The look is decent. Earlier had plain beige finished dry wall this just covered it as layer and some visitors mentioned it appealing but maybe just to impress and negotiate for good talks. All in all check the thickness before application and I learned this lesson so passing it.. dont go for claimed things blindly before investing so much of time money and energy

Very thick, look nice, seem to absorb sound. Difficult to cut.
