ZHERMAO 12 Pack Hexagon Acoustic Panels Beveled Edge Sound Proof Foam Panels, 14"X13"X 0.4" High Density Sound Proofing Padding for Wall, Acoustic Treatment for Studio, Home and Office (Grey Red)

Honestly I’m in a basement and I don’t think they absorb to much sound. Which is no big deal I was looking for more of accent panels to make my Govee light bars stand out and not make the wall look so boring. And these were perfect! The adhesion was fantastic. If your looking for sound absorber probably steer away but if your looking for something to put on your wall the blue looks perfect and made my room pop more!

Sticks well, but I cut the plastic in half to only use the top of the adhesive. I’m hoping it makes removal easier & I could reuse by taking the rest off next time. Plenty of stick when using only half the self adhesive backing.Cuts echo in my highly reflective home office. Great noise reduction, and elimination of echo in home office. They do not block sound, nor should anyone expect that from this cost effective product. Blue is very dark as you can see, and white is a nice bright white.

Don’t mind the Doritos in the pic but they work well look good and stick great. Put some little lights through them so I look like I paid a little more than I actually did 🤫

These are amazing! The entire back being double stick tape is great and a time saver! I’m putting them on my entire ceiling for my theater room. Being less than 1/2” thick I know it’s only absorbing the higher frequencies, ~15,000 Hz and up (guessing on frequency) but they also help reduce the reflections from the screen. Easy to cut scissors or utility knive. Shipping has been quick and after ordering 20+ packs but have only put up about 10 packs, there haven’t been any noticeable sizing discrepancies.

These are very uniform build quality and works well with command strips. much better than square foam panels.

Got these to reduce echo and noise from voices in a concrete room. We actually did acoustic measurements before and after treatment and discovered these panels only realistically absorb above 4khz. The main vocal range is around 500hz to 1khz so this was basically useless for absorbing vocal noise. In addition, this made the room sound 'dead' and not in a good way. It sounded dull and flat and lifeless with these installed.To absorb voice you need at least a 2" thick fiberglass or similar density and thickness. I will be returning at least some of these panels (in some areas we do want that high frequency absorption).Also these panels do not have any adhesive included. You will need to use double sided tape or glue or some other adhesion.

Moved downstairs into a new office space and was told that the echo in the room was noticeable on a call so I bought these shapes to add some style and hopefully dampen the echo. I applied them using your typical peel and stick command strips and they’ve been hanging and reducing echos ever since. Coworkers haven’t noticed any echo, the product is clean and without irregularities, looks nice if you like the aesthetic, and was very simple to throw on the wall if you buy yourself something that’ll stick to the cloth material. Very happy so far worth the purchase

Not Bad but not the best should be at least $15 cheaper (I mean you don’t even have adhesive strips with it and all of the panels don’t fit perfectly together) as a matter of fact if i wanted to fit them perfectly I would need to cut the edges which I should not have to do for the price (at the very least you should make sure all panels fit together like a puzzle..)there are not adhesive strips so you need to get the 3m double sided tape extra strength 30 lbs works the best and to get the most out of it you need to couple it with bass traps and other sound absorbers. Overall they are okay at best especially due to the price no way these should be almost $40. You will do a better job cutting up any left over memory foam not in use lol.

Does the job as expected. They are not very thick so I would recommend not putting them against the wall directly but against a wood base to trick sound.

Really of good quality and sizes are accurate... Happy with my purchase... They are quite big but still not enough..need a few more to complete
