4 PCS Acoustic Wall Panels, 2“ Thick 23.6" x 11.8" Fiberglass Recording Studio Acoustical Treatments Panels, Sound Absorbing Panels for Studios, Office, Home Theater. Beige

Easy to install & they absorb most if not all of the echo & reflection distortion, made a huge difference in my surround system & my system is high quality with a dedicated OSD nero xa 5180 . my system is performing better than ever before with these panels & other foam sound absorption 12×12 panels

These work great and look great, what more can you ask for? I got three packs of these and wow do they make a difference when listening to my stereo system. I'm very much a believer in room treatment now and these are wifey approved. Enough said.

Our clinic has barn doors which look great aesthetically but are not great for sound so we tried these out. I was skeptical they would work but I'm pleasantly surprised. Only complaint is the first few days after putting them on the wall a few would randomly fall off. Definitely recommend letting these acclimate in the room for a day or two before sticking them up. But overall very happy. We bought more for each exam room.

These not only look good, they actually work for my small studio and the adhesive is extremely strong.

They work will however the double sided tape will need some reinforcement to stay on the wall. I eventually remove the tape and use hot glue right on the surface of the panel. That work well.

For my case they do a decent job. It’s not because the product isn’t good, it’s because I place them centered for aesthetics/design. In that wall I have two desks. The results can be better if placed right in front or behind your sound source. Easy to install, let’s see how long they stay up

Great sound dampened, my townhouse has standard insulation in the walls so my tower speakers were bothering my neighbors. After easy, quick installation we've had no more complaints

I installed these panels in our office bathrooms to stop the echo. They look great but the next morning they were all on the floor. I am returning them asap.

One year later and still stuck to the wall. Helped reduce the noise around the laundry room..

After buying a new TV, it's sound comes from the whole screen. The problem is as much sound comes out the back as the front. A loudspeaker would kill all the rear sound by having absorbent material at the rear. I put these directly behind the TV, it killed dead any rear reflections. A bit expensive, but it worked.

Overpriced, and at best moderately effective.

Excellent quality panels and excellent customer service. These panels definitely help to reduce echoes and reverberation in my home theatre room. I can't say enough about their customer service. I contacted customer service as I was looking for advice on an alternate way to hang these panels. I did not want to permanently stick the panels to the wall. Upon asking, they then explained that they have brackets for these panels. They then proceeded to send me the hangers free of charge. The brackets were pretty straightforward and easy to hang. I couldn't be happier.

With 12 foot high walls and a vaulted ceiling, the sound from our cabin’s living room echoed loudly in the loft. After installing these acoustic panels, there was a noticeable difference, but still echoed. We’d probably benefit from two more sets to get the desired results. Thankfully, the panels themselves are attractive, albeit plain, and we’re looking forward to the aesthetic of mixing gray panels with the black. The panels themselves are heavier than expected, but mounted easily to the walls and the adhesive has held them firmly in place. I don’t know much about sound absorption and decibels. All I needed was a solution to reduce the echo upstairs, and these panels are the way to go.
