I really like the original HE-400 with the white drivers prior to it being returned and made brighter. I'm really curious as to how the HE-400i differs sonically from the current version.
Lighter = win. Seriously, the new Audez'e models are even heavier than before, so it's nice that Fang is at least trying to make things more ergonomic.
That being said, those new headbands.... yeeesh. They remind me of the plastic headband on the first KingSound e-stat headphone. The black gimbals are totally mismatched against the wood. They look like they'd be prone to breaking rather easily.
Also seriously Fang, ditch those connectors already and adopt mini XLRs!
