Is this to protect the cable, headphones, or amp? Most headphones with detachable cables don’t detach very easily. It’s more likely that the Schiit stack comes flying off the desk rather than detaching at the ear cups. I wonder if you could buy a headphone cables designed to break away? The Sennheiser IE800 actually had that feature where it could disconnect right below the Y-split.
All the above.
And yes you can, Meze’s 99 series comes out pretty easily.
