50 Pack Acoustic Panels Soundproof Studio Foam for Walls Sound Absorbing Panels Sound Insulation Panels Wedge for Home Studio Ceiling, 1" X 12" X 12", Black (50Pcs, Black&Blue)

I really like these they look amazing in my office and really transformed the place as well as providing some shelter from the loud groanings of my 3D printer humming away in the other room. Sound suppression is evident. They also add a small amount of insulative value to the room. A cheap DIA makeover for sure! There's no smell after putting them up I guess I don't smell anything from them. They've held up now for several weeks and no issues. The foam cuts nicely and looks uniform and I have no issues with its quality.

These panels are about 1x1 foot. They are not as thick as I had expected, but they are decent. There is no fasteners or mounting adhesive included. They come vacuum sealed in a few separated bags. They look great on the wall in my studio though!

My son loved these and he put them up himself. Needed large sticky squares tho so they would stay up

Me parece muy buen producto, lo coloqué en el cuarto y minimizó la acústica en más de un 50 por ciento lo recomiendo.

I got the 50 pack black and blue, and 50 pack black. These filled out nice. They are not meant for noice canceling, rather a slight reduction in noise. My main reason for buying these is to make my space something I like, and make it a little more cozy. I thought it came with something to adhere it to the wall but it did not, so i got the 3M super 77 and they hold up pretty well so far. It's a nice product for the money. Don't let them sit in the sealed bags for too long or you might have different results.
