Skipped 6xx pages... yikes. So much activity.
I've only seen one O2 and it might have been a custom case too. But that seems pretty big. Hope I can stack things over it.
I know. But as I've mentioned it in the T50RP thread before (I don't expect you to have read this, btw, don't worry): modifying headphones is not much different from modifying speakers. Headphones are just smaller and have the ear-side cavity to consider. The rest is identical. People putting fiberglass in speakers ----> people putting fiberglass in headphone cups. No difference aside from scale, yes?
Just that orthos/planars are more sensitive to modifications on the rear side of the driver/speaker unit so some things may or may not apply. Give you a general idea.
600 pages?!!? Seriously?!?!
@Everyone who wants to read my main college essay
OBVIOUSLY it has been spiced up.
