it stays put on the ear but bothers the inside of my ear and caused a slight abrasion. It is easy to take on and off of my headphones, and without it, the mount is barely noticeable. This is the only way I know of to see inside your own ear. Originally rated 2 STARS because chargeplay clutch charging mechanism arrived defective and would not charge my Samsung Galaxy Note 10+ for more than 1-2% before shutting down. The cork makes it mold to your foot and it?s incredibly comfortable. I was worried about my high arch, they fit perfect. The metal of the screws is very soft I had to use different screws to anchor in the hook. Its definitely things to RETURN! It went together easy with hand tools and turned out pretty square for what it is. Appear same as original hd800s headpads.
