These are excellent and my HiFi Man Edition X V2 headphones fit inside perfectly. Considering Hifi Man doesn't make a case for the Edition X's this is awesome.
Very good protection, you can't push the case in anywhere besides the zipper unless you apply a lot of force.
Ether C does shake a lot in the case, and the padding feels nice, but it's not plush. So it's good to store headphones, but not for travelling.
Can double as a headphone stand.
It should have a better fit for the Ether (so it doesn't shake around), as well as more padding on the inside.
