Acoustic Plank Panels, Sound Absorption Wall Tiles, Slate Grey Color, Sound deadening, diffusing and Insulation Art Treatment with Beveled Edges, 8 Pack Mixed Sizes

These have been hanging on my wall for months with double sided tape. They are fairly light, and are adequate quality. They are kind of pricey for what/how many you get, and I will need to get at least one more set to get the level of sound damping I want. If you just need to kill the echo in a room these will do the job, but if used with a home theater or stereo you will likely need several sets

Nice looking acoustic panels that compliment the decor in my home office. They helped dampen the echo in my office where there are a lot of hard surfaces.

These sound panels are great. The perfect size to arrange in an artistic way. Super light weight and easy to hang on the wall. Definitely recommend.

Just what we were looking for

They work great 👍🏿

These look fantastic on the walls but unfortunately my pet cat is deathly afraid of them. She won't come out to the living room when these are up, and gazes at them with a 1000 yard stare from a distance. I had to take them down. Not really the product's fault, so I'm rating 5 stars, but man, what a bummer.

The panels are light enough that canned spray adhesive held them securely to a wall while remaining removable, making installation easy and leaving me the flexibility of moving them around.They also reduced resonance off walls in my room well.
