W/20 hours the sound is bad, close and dark, too much bass.
You will have to wait til 50 hours for a better performance.

I am interested in your headphones.  Sounds like you haven't had them for long?  They must be in pretty near new condition?

Best,

If you haven't already made a decision on the sealed headphones, perhaps check the datasheets on innerfidelity.com, attenuation does vary a lot.
