Fischer Amps Adapter Rings Shure SE-Series

I bought these adapters half a year ago. At first I was afraid of breaking my Shure SE215 headphones and thus was unable to push the headphones deep enough into the adapters. Because of this the isolation was poor and the headphones kept on falling out, which was infuriating at times. A few days ago I tried pushing the adapters further and was able to push them past the ring inside the adapters. Now that the headphones no longer fall out and the isolation is much better, I am very pleased with the product. If you have these adapters and are having issues with the headphones falling out, you should push the adapter so that the top of the adapter reaches the "body" of the headphone.

Would give it a full 5 stars if there would be instructions on how to "install" the adapters.
