I purchased these since everything was included and the price was very inexpensive. The 9" ones I used for vinegar, oil, non-stick spray cans etc in an under counter cupboard. Soon as I put them on, noise around me was canceled out, wow, this is so cool. Overall, I am pleased with these slippers. unfortunately due to personal issues im over the allotted time for a return and refund but il call tomorrow and see what is said, everything crossed That being said the mic is the best quality of all I?ve tried. However, he loves these. It is clean, rial and clear with no static. A little bit harder than other CROCS, but hopefully will grow softer when worn more. mes attentes face au produit sont comblées.
