The system comes with 3 different microphones, which is very handy. They fit as originals and Im very pleased with them. I have size 11 feet and they fit so true to form it looks like the white outline was drawn around my own foot from the toes to the heel. They are extremely warm, perfect for cold weather. You can drill if you want to or else there is a tape hook which you can use. Styling is sharp, with a subtle silver shine to the front of the foot. They do an awesome job cleaning Sound quality and battery life are great, as is the ability to use while plugged in and charging. The shelves are sturdy and hold 20 spice jars. This is needed as I just got my first real entertainment center and am getting a vinyl tower delivered tomorrow.
