These pads do the job they're intended for - they soak up surplus vibrations from any monitor or speaker they're placed under. I bought these pads to use with a pair of KRK RoKits and they are entirely suitable - the perfect size and depth for these monitors.
I like that the pad comes in two separate pieces, which means our monitors or speakers can get tilted and adjusted as you please. The two parts can be used together or separately, depending on your requirements, which is a cool feature.
The quality of the foam that the pads are made from is good, the pads are very thick and strong. They absorb vibrations and sound very well, which was important to me living in close proximity to some non-music lovers!
The only negative I could find with these pads is that the label printed with the thomann brand name came off each pad within days of their arrival. After several attempts to stick these labels back onto the pads they just wouldn't stick! Perhaps the brand name should be printed on each pad, or the sticker left out altogether.
The pads are a good colour and will blend into any studio setting. They are subtle and don't take away from the monitors that they're designed to serve.
All in all these are good, inexpensive pads and I would recommend them.
