HungKaiAcoustic Foam Sound Panels Wedges Soundproof Sound Insulation Absorbing, 2x12x12in (Pack of 12)

Applied a few of these to two sections of the walls in my streaming room, just to reduce the echo a bit. They do the job well and are very lightweight, and can be supported with two small pieces of 3M double-sided tape at the back. For the best outcome, unpack and let the panels sit out overnight to expand, then separate each one and carefully separate each individual square on each panel, as a lot of them are going to be stuck flat. Once you've done this, leave the panel for another day overnight and they'll be good to hang up.

This product has improved my music room experience. It reduced the unwanted echoes and rebounding sounds.My music/theater room is now my favorite place to hangout everyday.It's actually has a mini bar, home theater and a music room as well. My friends come almost every weekend as the experience is really superb and relaxes from work stress...I encourage the other enthusiasts to install these foams on your walls to enjoy and escalate your experience.By the way, I used a glue gun to fix on the walls as the double adhesive tapes does not hold well. The glue gun does not damage the walls also if you plan to remove in the future. Foams are also usable.

Purchased the item for our company machine shop. The first impression was very disappointing. But performance made us very happy.

I bought for my gaming room but I didn't like it. Didn't fit well together.

The look is good but the size of each square is not even accurate nd sum r bad shaped nd came in a bad packaging

Lacks density but I bought so many of these they might do the trick.

It’s ok not bad it’s would been better if it was a bit thicker however not bad for the price.

Don't use this for trying to soundproof your wall , don't waste your money
