12 Pack Self-Adhesive Sound Proof Foam Panels for Walls 2" X 12" X 11"， Fast Expand Acoustic Panels with High Density, Soundproof Wall Panels for Studio and Home Noise Reduction Black

If these are what you're in the market for they are great, exactly as described. Customer service was great too.

This product works as intended, but it should have perforations to customize the length to match your speaker footprint. Cutting it yourself, no matter how careful you are to try and cut straight, will turn out looking terrible.

I recently set up a dedicated vinyl listening system with larger powered speakers and needed something to isolate them from the table and these worked great. They are comprised of 2 pieces so you can customize the orientation for flat mounting or angled mounting. They do exactly what they are intended to do and eliminate vibration from the surface. Great product and great price.

These foam pads are better than nothing to help decouple your monitors from whatever they're placed on, but are not the best choice if you want to place your speakers on their sides. Note the dimensions on these, to ensure your speakers won't overhang on the sides or back. (A little bit is probably OK sound-isolation wise, but not if you want them to "look" right.) Time will tell how long the foam lasts before compressing from the weight of your speakers and/or disintegrating from age. All in all, not too bad a deal.

These speaker pads are perfect for both proper aiming of computer speakers as well as isolating vibration between the speakers and hard desk surfaces. The specific cut of foam piece allows different speaker placement angles. The foam is firm enough that they easily hold the speakers in place at the desired angle, and yet also comfortably reduce any resonance from contact with the desk. The instructions included weren't for the foam pieces, so not sure what happened there, but it's not rocket science, so easy enough for anyone to figure out how to assemble the two pieces.

First off, the order didn’t even come with enough stickies to complete the set of foams that they sent. Rather, there is a message printed on the back of the wrapping that says “if you need extra stickies please email us.” I emailed a week ago and never received a response. Secondly, these things don’t even stick to the wall. After two days of being on the wall, they are already starting to fall off. Cheaply made product, would not recommend.

only half were any good.

Overall: Recommended! Nice isolation pads work just fine. The foam could be durable but maybe that's about the same for all of the foam : ) Cheers!
