Would've been nice to know the wall tiles don't come with adhesive but the shipping was extremely fast and they work great. Not the perfect solution to noise but helps to muffle loud sounds you dont want everyone to hear.

I bought this pack of 24 pyramidal acoustic panels of 12 x 12 x 2 inches to improve the acoustics of my home studio, and the truth is that they exceeded my expectations.From the first moment, I noticed a significant reduction in echoes and reverbs inside the room. The pyramidal shape helps to disperse the sound waves evenly, which improves both the quality of the recordings and the overall listening experience.The panels are of high density, which translates into more effective sound absorption compared to other thinner or less compact models. In addition, the fact that they are fire resistant gives me much more peace of mind when using them in closed spaces with electrical equipment.Another point to highlight is how easy they are to install. With a good adhesive (not included), the panels are easily fixed on both walls and ceilings. The black finish gives a professional and modern touch to the space.

It works well but there’s no adhesive, it would be nice to have product description to inform customers.

I'm a music producer and have worked in studios for 20+ years so I know acoustic panels.Let's get one thing out of the way: these are beyond cheap. Half of them didn't inflate, yet just enough did that I can't force them back into the box so I can't even return them for a refund. They do not have adhesive and are not easy to mount.All acoustic foam I've ever used are made of thick material and you can immediately hear a difference after installation. Most panels of this size are designed for absorbing and diffusing sound in the mid and high frequency ranges. After testing using a microphone, there isn't much of any difference without without the panels.I only bought these to use in an AirBnb for a month and even so I'm disappointed. These are completely useless and un-returnable.

Have not noticed a difference in sound. Keep falling off the walls.

I have panels from bed level up but wanted a less expensive option for wall behind to floor. These work. Used double sided tape on some panels and just a flat head screw in center on others for comparison. All packed tightly together. Would recommend both.

GREAT
