TroyStudio Thick Acoustic Foam Panels, 13.8 X 11.8 X 2 Inches 12 Pcs Hexagon Sound Absorbing Foam, Dense Soundproof Padding Tile, Recording Studio Foam Absorber, Decorative 3D Wall Ceiling Panel

These worked really well for my purposes, which was deadening the wall behind my studio desk. I had recently gotten into producing YouTube videos and the space I'm using left a lot to be desired in terms of acoustic performance. I am happy with the performance of these panels. They look good and are cut really well. I got them wet and dried them in the dryer, that really seemed to allow them to expand fully. I used a double-sided adhesive tape, Gorilla maybe, and that has held up well. Overall, I would recommend these and I plan to purchase more in the future.

I used these for a car install. Look cool and go together in interesting patterns. Take them out and let them decompress before installing.

Thickest foam hex I could find. But the vaccum seal seems to have destroyed the edges of 1 tile, making it aesthetically unusable.Update: I received a replacement pack and in total 5 of 18 tiles were damaged cosmetically on the corners, seemingly due to vacuum packaging.

thought it was not as thick but later realized decompression instruction is on a tiny card. After decompressing, it is as advertised

With a bunch of noisy kids in a small apartment, I'm always looking for ways to minimize the nouse that travels through the walls to bother the neighbors! These are nice and thick and the hexagon shape makes a nice design on the wall behind the tv. They make the sound clearer in the living room, so I'm gonna assume that means it's not going through the wall as much. They came super compressed, but fully expanded just by leaving them sit.

Purchased to give some texture and cancel some noise from the next room. Worked great. I’ll probably hang more but this is the beginning stages of redoing my photography room/office.

Some panels came damaged. Trying pretty hard to get just a handful of them replaced but to no avail.

Good
