4 Pack Curved Bass Traps Corner Acoustic Foam, Large Size 16.5" X 6.3" X 12" Sound Absorbing Corner Bass Traps for Studio and Home Theater Low Frequency

Huge difference in quality and sound in my at home studio! For me, these acoustic panels work amazingly and have made a huge change. The adhesive dots make for easy installation. Be sure to firmly press/hold the dots on the foam for a few seconds (5-10) before attempting to peal off the yellow sticker. This I found makes it easier for getting the yellow part off. The thickness of the panels is quite uniform throughout and minimal deformations (edges) if any. Great value for quality and quantity! I will definitely buy more in the future! 10/10 recommend

These acoustic foam panels are great. They are very durable compared to what I’ve used, very thick for the price, and I can’t say much for sound quality yet. I haven’t been able to test them in my booth. The only downside is that you have to wait a very long time for them to dry. I soaked them in a bath tub and then put them in the dryer and they were not dry. I did also buy 48 of them. But they are still sitting infront of a fan. They hold on to moisture very well. I would suggest letting them just sit out in the open for 48 hours instead of soaking them. Not the easiest to install because there isn’t many points of contact. But the adhesive it comes with works great. Overall. Great product. Looks good but comes with the price of not being able to stick as well as other foam panels.

First thing's first, I really like these sound dampening panels. They cancel out a lot of echo and deaden the room really well. I also appreciate that unlike egg crate or other repeated pattern, this are a nice differing pattern when mounted 90 degrees from one another each other panel. The two rooms I've installed these have a much better sound, without any echo or noticeable sound waves bouncing off the walls, even in a really clean recording. I have purchased many batches of these over the past month. They are terrific. I found them easy to mount with the supplied stickers. I was doing it wrong for the first 5 or so, trying to pull the backer off of the dot "free hand", before I stuck one to the foam. Terrible idea. If you peel & stick in place, push pretty hard, the adhesive won't let the dots separate from the foam. Then it is a lot easier to bend the foam (and sticker on it), remove the cover and go. The only problem is that some batches come where they won't separate themselves from the adhesive that keeps them compressed. Another user posted a video having the same problem. I put pictures here to show you, when it happens, it is always on one side as they try to expand. They won't get unstuck no matter how long you wait. The first time I saw this, I meticulously went piece by piece trying to separate the adhesive, which then disappears, trying not to tear the foam. It never made them look as good as the batches I got w/o the stuck ones. MOST that I bought, including entire packages worth, were perfect and after very little time unwrap, were in usable shape. In the latest batch, there were a couple bunches with the adhesion again. I thought I'd try my heat gun. I noticed that the foam itself expands even further, like leaving them unwrapped longer would do. The heat gun didn't do much for the adhesive, though. I had read another user mention a steamer (thanks whomever you are), and I have one so I tried it. It was WAY more productive that pulling them apart by hand, which never looked like the other good ones. The steamer made many of them exactly the same size & look as the "normal" pnes. On some difficult edges, it didn't make them perfect, but significantly better. Without this final occasional step, I'd give five stars. If you get this problem, try steam or maybe even a very hot bath/soak as the maker suggests. I just didn't want to wait another day or so for them to dry. I'm always impatient on projects like these. Best of luck to you. These things are great!

Product does not do as promised. It’s generic foam that does ZERO to reduce noise. The adhesive is a little on the crappy side as well. Installing was Ok but for the amount of money I spent these DO NOT WORK. Definitely not worth the money . Build quality is ok.

I see many pictures posted here of the sound panels not fully restored to their original size due to the vacuum packing. The instructions say to soak the panels in water, but do not follow those instructions!! It will take days for those panels to dry. Instead put the panels into your clothes dryer at VERY low heat (not air dry) for around 15 minutes. You will find that this takes care of nearly all of the compression. what little may remain can be rubbed with your fingers and restored fully. I didn’t even bother using the ‘resting period’ subsequent purchase; straight from the box to the dryer and viola!Limit your dryer to max of six at a time.

If someone has a board or a wall they are attaching these to, they will work great. They do cut the sound down, and they are a good value for the money. They just aren't suitable for what I need to attach them to. I only have a wall divider, and they don't stick to the canvas on them at all..

Saw another review here saying to throw them in the dryer for ~5 minutes. They puffed up pretty nicely. 'Even threw in a dryer sheet to make them smell fresh. I expected them to be a bit denser, but they're kinda soft. At least they're pretty thick. I just moved into a new house and needed it for my dedicated studio room. The room door is a bit hollow and this did help take the noise level outside a couple decibels. I'm going to put some in the corners until I can build my own bass traps. I'd definitely recommend these if you're on a budget.

These bass traps are very nice and robust and come with a ton of double sided sticky dots, which I really appreciate. This was used in combination with 2 inch foam panels to surround it, which helped keep it on the wall. I would imagine if you used it alone, it will have trouble staying in the corners. It is definitely trapping bass when I'm listening to music and standing near it.
