Can't discuss the drivers? Avoid.
With the exact same specs for impedance and sensitivity, the HE4XX surely has the same or very similar drivers as the HE400i. The difference in implementation seems to be that the 4XX have a major roll-off in sub-bass and a slight emphasis in bass compared to the much flatter bass response of the 400i. Couple that less desirable FR with a less comfortable headband and what has got to be (if past Massdrop exclusives are any indication) lower build quality in a company known for uneven build quality, and the $170 price tag (compared to $250 for the 400i) doesn't look like much of a deal at all. I would suggest people look at the T50RP instead. Cheaper stock, much more of a known quantity, and more mod-able than any other headphone out there. Or just go the for the 400i, it's worth the premium just for the better headband and the beautiful purpley finish, if you ask me.
