Hello, @Hi1234 . . . thank you for letting us know what is going on with your EMO. I would advise you go here regarding where your head-phones are broken and falling off.

As for falling off of the desk top, yes, his sensors are not perfect. We recommend creating a space for him that has raised borders. Here are some suggestions in this thread.
I hope that your EMO will be working as optimally as possible and that you can have a great experience with him.
Let us know how it goes!
