JBER Sound Absorbing Foam Panels, 48 Pieces 2.5 x 30 x 30 cm Acoustic Insulation Wedges for Studio Soundproofing Padding Fire Resistant Acoustic Treatment Foam (Black and Red)

Not good at all for sound proofing

The 2 photos are the before and after. I can say one thing. It definitely LOOKS nice. If you want to be decorative then these are definitely worth it. However, we buy these for sound. I will say in my honest opinion, I notice a good difference between having nothing and then adding this foam. My echos are not as noticable if at all, and the natural sound my mic (blue yeti) picks up has soften even more. I like to record gaming youtube videos and play alot of horror games. So when I scream (since I'm scary) some (not alot) of echo gets picked up. So if you're big in audio you'll notice a difference but at the same time everyone's area is different. I also should add, the packaging comes in very clean. It's vacuumed packed so wait about 24 to 48 hours for the foam to take shape before placing them on the wall. I advise cutting a small slice into the packaging to let air do it's thing. As for mounting them, nothing comes with it to do so. Thankfully, I have many command strips that worked beautifully to mount these. However, make sure the strips can hold atleast 12 pounds due to when I used the smaller strips the first few foam fell off the wall. I bought 2 of the 48 pack and have about 12 each color left over. The foam is reusable but I will definitely buy more if needed. Considering how many you get in one packaging, I personally say they're worth the money. I sincerely hope my review helps your purchase!

I was honestly surprised at how effective these soundproof wall panels are. I bought them to cut down on noise between rooms, and they’ve made a massive difference. Installation was super easy—just peel and stick—and they actually look really sleek on the wall. The material feels high quality, and you can tell it’s designed to absorb sound rather than just block it. Since putting them up, I’ve noticed way less echo, and outside noise has dropped significantly. Perfect for home studios, noisy neighbors, or just creating a quieter space in general. Definitely worth the money. I’ll be buying more as I have run short on the wall that’s pictured.

Me encanta lo manejable que es y la calidad del material. Lo utilice para insonorización de mi estudio de grabación

Everything just seemed to work perfectly fine with these soundproofing panels. The adhesive worked and is continuing to work perfectly, i even have some up hang on my ceiling and they are still sticking! the also do a good job at keeping the noise and echo to a minimal level that is acceptable Overall, i have never been more happier with a purchase!
