TONOR 4-Pack Bilayer Acoustic Panels Large Self-adhesive, 47.24” * 23.62” * 0.72” Adhesive Wall Panel, Large Soundproof Tiles for Echo Absorbtion, Acoustical Barrier of Polyester Fiber, Black

Excellent, hard fibre weave and not the normal squishy foam squares. Looks good and was easy to install (Stanley knife needed for trimming). I will be ordering more in the future

Great product well made very sturdy it is quite thin but they are very robust did exactly what I wanted to.. Reduced the echo in my home theatre and the glue on the back is unbelievable so strong once it sticks you won't be able to reapply.

I’m glad I purchased these, although I know they won’t soundproof neighbours DIY noise ( his hangs wallpaper with a drill and hammer I’m sure ) but I’m hoping the slight bass I can hear from their tv might be muted a bit. They were delivered promptly and very well packaged. I stuck mine to the wall with wide heavy duty Velcro tape 5 squares one in each counter and one in the centre, I was apprehensive about sticking them directly to the wall incase I need to remove them if I move. As the wall I wanted to put them on was about 6cm taller than the panels I finished it off with led lights in a fitment along the top, and am really pleased with how it’s turned out. I started from the light switch as so had to cut I for the light switch and rather than cut a hole in the middle of a panel I could just cut 3 sides, and was easier to line it up, cutting was fine with a very sharp Stanley knife, I brought the light switch forward so to be flush with the panel by using 2 extension plates for the switch & popped a finger plate to avoid finger marks on the panel. They look good and make the room look bigger, I have another pack coming tomorrow to put around the 65 inch tv on the opposite wall, neighbours have made no mention of heating my TV but with issues with the other neighbours it’s made me aware that mine may inconvenience them and the panels look good so I may as well fit them. FYI I’m 66 & disabled so believe me they are easy to install and I didn’t need any help with them.

Really good quality, easy to fit. Get a good knife/scalpel and metal ruler to cut them

I am really happy with this. Easy to put up and looks good. Great value. I bought it to improve the looks of a boring white wall so I wasn’t worried about the acoustics but as an added bonus the tv definitely sounds better. Highly recommended.

Certainly isn’t white. It’s grey. Would send it back if it wasn’t for the fact it’s… you know… stuck to the wall. It also does NOTHING in terms of soundproofing. Please see attached video - this is through a party wall. Update: I have changed the review to a 3* review because the company reached out and resolved the issue for me. The colour and effectiveness are not to my expectation for the price, but their customer service is impressive.

Used this product as a wall protector for dartboard, brilliant for this and easy to use and cut. Dartboard fitted to it fine and nice and solid. Would definitely recommend these sheets and also looks really good up.

Excellent sound dampener. I fitted these in my new log cabin/home office and could not believe how much they helped to eradicate the hollow echo from my voice when on calls. It took a few attempts to locate the best place to put them, but now they are in place they are working very well. Also very classy/upmarket aesthetic, quite a few Teams callers have complimented the professional look.

Purchased for our large front entrance to help with sound barrier and reduce the echo in our house. Works great!

Super efectivos para reducir 5decibeles . Valen la pena cuando es algo minimo

Couvert toute une pièce avec ces panneaux pour une meilleure isolation acoustique, le résultat est conforme à ce que j'espérais.

I added some of these to my audio room to treat first reflection points. The effect is noticeable. No out-gassy smells from the panels. Glue is VERY sticky. They are not removable without ruining the panel or wall surface, or both. Can be used on a ceiling without worrying about it coming off. Packaging was excellent, panels arrived in perfect condition.

Looks nice and It will work for my application. Only 4 stars as white is not so white, more like light gray
