Amazing soundproofing
I recently installed the Soundproof Wall Panels in my home office, and they’ve made a noticeable difference in reducing noise. The panels are easy to cut to size if needed, and the installation was straightforward. The sound quality in the room has improved significantly, and I no longer hear as much outside noise or echo. Plus, the sleek black design blends well with my décor. These panels are a great investment for anyone looking to improve sound quality in their space.

Good quality panels
These are solid sound panels with a nice strong adhesive on the back for easy installation. I do think that, for the price, it should come with more panels. That said, good panels aren’t cheap and these are a good size. Perfect size for what I needed them for!

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.

Okay for privacy, not a sound wall
Color: Gray, Size: 72" wide, 66" Tall
Ordered this for a home office, it is easy to put the panels together, one man job. They look nice, stand up well, and gave privacy and seperation. You can tack a white board to them. These panels have absolutely no sound reducing properties that I can ascertain, so if you are ordering them as 'accoustic" type panels you will probably be disappointed. For making a cubicle they perform well.
