12 Pack Sound Proof Foam Panels with Self-Adhesive, 12 X 12 X 2 Inches Acoustic Panels, High Density Soundproof Wall Panels, Studio Acoustic Foam Panels for Office,Vocal Room, Bedroom Walls (Black)

Very easy to stick on the wall. I tried other brands & these are the only ones that stay where I put them. I'm constantly reattaching the other brands. The foam is even more dense than the others. I'm considering buying more of these to replace all the others. Sound reduction is noticeable. My neighbors still hate me, but at least they *think* I'm playing guitar quieter. Haha. 100% recommended.

These turned out to be an excellent, quality product and suited my needs perfectly. Tamed an area that had severe subwoofer reflections and made for a significant improvement in room dynamics. Can be cut to fit and have excellent adhesive properties.

Works amazing. Definitely need to get more!!

Had to return it as the glue is not strong and does not stick for long

This product was very easy to apply and install. I love the fact that they are limiting packaging by shipping these flat, great sustainabilty play there.

Bought these to put in my boys’ bedroom window- we have a chicken coop that sits right outside it and the hens have been super loud and waking them up too early. We have an old house with zero soundproofing and the windows are old single pane bubbly glass. The first night they slept an hour later than normal and I was up watching the chickens on our cameras and they were up at the crack of Dawn like always! Can’t wait to put them in our windows of our own bedroom to muffle the noise from the street. Bonus- they also help keep the room cooler!

Works perfectly.
