UMIACOUSTICS4 PCS Acoustic Panels, 2“ Thick 23.6" x 11.8" Fiberglass Sound Proof Wall Panels, Self-adhesive Sound Absorbing Panels for Studios, Office, Home Theater. Deep Black

Make a massive difference, i have them places around a motor running in my shop, I see a 3db drop in the middle of the room.

These are well built and help absorb noise. Easy to mount stickers but I preferred to add picture hangers in case I want to move them around.

Really good, but do not use the adhesive to affix these to your walls. You'll want to attach some or another frame hanger.

I think these are awesome. As someone who is upgrading from the cheapo foam panels for my music studio, these are much better. The fabric feels great, size is good (wish they were a tad larger-but this size gives you better customization abilities). I have not tested how this changes the sound reflections in the studio just yet, so I can’t speak to its functionality at this time.Overall, I’d say these are a fair price for the quality I’m seeing so far. They also just look great on the walls (especially if you get creative with staggered placement). Could they be a tad cheaper? Yeah, but not by much. Will likely be buying more of these or any of their other products.

The panels work well and are pretty good quality but the adhesive is quite bad. I stuck 5 of the panels on the wall, all side by side, and within a few days they all fell. After about 10 hours after putting them up, the first panel fell onto one of my monitors breaking it. 2 days later, the other 4 fell at almost the same time. I would still recommend getting these, but just make sure you have another way to mount them to the wall instead of relying purely on the adhesion tape. Also the panels appear to have no mount on the back to screw them in.

I have a small 11.5x7.5 recording space. Untreated, this room's echo and reverb made it unusable for vocal recordi9ng. Treating my space with 4 packs of these made a world of difference. My my vocals sound clean, dry and professional, no unwanted reverb. As my spaces get larger, I will gladly order more of these. For the cost, they can't be beat.

I'm at a loss of words. I am extremely impressed by the quality. Great packaging also.

these suck. they pulled the paint off the wall and the adhesive guard got caught on the adhesive strips too. would never buy again
