New Level Blue Column Acoustic Wedge Studio Foam Corner Block Finish Corner Wall in Studios or Home Theater (8 Pack)

This is NOT acoustic foam, this is just a junk piece of very light foam that does strictly nothing.As a test I put one ear next to a very serious foam panel and the other in front of a speaker. Then I placed the foam in front of that ear to see how much of the sound it was taking off. I then compared it to one sheet of paper and the foam was slightly better. Then I compared it to 2 sheets of paper together and it was the same.In other words, this form is an illusion. The only use I can see for it is if you have clients coming in your studio and want to make it look acoustically treated just to appear more professional.

These are working great for my use in my home studio. I have plenty of other wall treatments and acoustic panels to tune my room and use these in several corners to keep high frequency build-up from affecting my listening and recording spaces.They are a little small, so you might want to add another wider version of the same thing if you really want to deaden your room acoustics, or add other wall treatments in conjunction with these.For my flat acoustic panels I build frames but for these corner panels I attach directly to the wall. The only issue I have is finding a useful adhesive; I do not want them permanently attached but I also don't want to keep re-attaching them every week. NOT the fault of the corner wedges! Just trying to find a good adhesive.Anyway, these are a great value; they are not high-end but do the job very well for the price.

I bought these along with some of the bass traps for sound management in my home theater. Very happy with the quality and the results so far. The color, burgundy is a nice match and blends well. I saw numerous reviews complaining out trying mounting with glue or double sided tape without good results. They just went up so I won’t know long term yet but I bought a box of 2” T pins (used in crafts and clothing design) and tacked the pieces to the wall. Hid them in the cracks and you can barely see them!

These definitely have a smell to them. I had to let the product air out for several days due to the smell. They do not have any sort of adhesive. I chose to use command poster strips. Unfortunately you have to place multiple strips to keep them from moving. They reduce sound effectively. They were used as my bedroom echoed horribly which made the sound louder. They also reduce noise from the kitchenette on the other side of the wall. They are effective, however having their own adhesive backing would be a major improvement.

These are an inexpensive option to help enhance your sound conditioning. The type of foam they are made from is less capable of absorbing than it is of deflecting. For the deep bass sounds you typically get bouncing out of your corners this might be enough for you. They do help to break up the sound signatures so they aren't being focused back to a center point, but in the end they aren't very effective at absorbing sound. If you use these you shouldn't count on them as a primary sound conditioning solution. They should be used in conjunction with some other sound absorption method.

I do narrations for my youtube videos in my bedroom and the echo has always been a problem. This product doesn't completely eliminate the issue, but it does reduce the echo quite a lot. I've placed 4 of them in each top corner of the room. For the price to performance ratio, I couldn't be happier with the result.Pro tip: I've used command strips to install the foams. They work great without the worries of peeling the paint when you have to remove them.

Difficult to get staying stuck to my walls but from what I can tell they work fine.these stick a little easier than the bass trap ones
