PneumaticPlus 4 Pack of Anti Vibration Pads 3" x 3" x 7/8" Rubber/Cork Vibration Isolation Pads

After contacting the producer he has been very helpful and he sent us back the product for free.

f you're a vinyl collector, you know that foot traffic or speaker feedback can ruin a listening session. I used these 3" x 3" pads to isolate my turntable, and the difference is night and day. The cork-and-rubber sandwich construction absorbs low-frequency vibrations that standard feet just can't handle. It completely eliminated the "needle skip" I was getting when walking near the setup. It’s an industrial solution that works better than high-end audio isolators triple the price. If you want a dead-silent background for your records, start here.

I am using these to quiten an external drive with a bunch of HDDs in it. These do help the sound from traveling through the floor as loudly but not as much as expected. I am not 100% convinced they were worth the cost.

Having bought this product to isolate from the floor, a couch which has a 100Watts (rms) bass shaker bolted to the frame and I am very satisfied of the end result. The sound vibrations aren't transmitted to the walls and surroundings anymore since I fitted every couch support with this product thus doing exactly what I expected. Therefore, I cannot speak for other purposes but for those looking to isolate audio equipment, subwoofers, speakers, bass shakers... look no further. Great price/performance ratio for audio acoustic isolation purposes

Actually removed the vibration noise from my 3D printer~

Realised product very small shortly after I ordered, but was already too late even if the delivery was scheduled in a couple of weeks. Cancelled but order arrived anyway and practically impossible to return, so check properly before you buy! I didn't have a chance to try if they actually work because too small so useless addition to my garage.
