96 Pack BLACK Acoustic Foam Panel Wedge Studio Soundproofing Wall Tiles 12" X 12" X 1" (96BLACK/RED)

I paired them with soundproof foam boards and it kept out my neighbors annoying little girl who screamed all day long. Which is loud if you live in a mobile home. They are effective I used duct tape to tape them to the boards.

We used these to make a sound dampened practice booth in our garage for my daughter. She is in her masters program and an opera singer. She needed a place to sing at full and not bother the neighbors. The panel made a perfect dampended space and dramatically cut the noise outside the booth.

It works just as anticipated. Good value. Expect to soak about half in water, but after they dry, they are as good as new.

Be warned this is not Sound Proofing at all, but these squares have removed all the echo and saved me from having to buy an extremely expensive microphone attachment.Best price I could find.

The media could not be loaded.  For the price it works as intended. My volume on stream sounds much better with no echo. Worth the purchase if you asked me.

They came packaged air tight and once you open the packaging and let the air in they expand. They were a bit difficult as far as getting them to stay on the walls. If you are in a rental your options are limited to what doesn't cause damage when removing. I used Loctite mounting putty and they still fell off after a month or so. Also some of them didn't expand to the full 1" depth. Not sure I would purchase again. There are way better options out there now.

Great

Awful adhesion! Have tried two different kind of tapes and they still won’t stick to the wall. Waste of money. So disappointed since I can’t even return them now. One star because the sizing is good.
