They sound completely different than AKG 70x. 70x is a very flat,linear sound with a treble shelf that boosts the treble levels, much like HD800. They have a vastly wide soundstage and are immaculately detailed, but they can also sound thin and harsh due to the treble shelf and overall lack of bass impact (though they have great bass extension.) Also they're harder to drive than a lot of people presume.
HE-400 is a lusher, fuller headphone with tons of bass presence and extension. Its soundstage is extremely closed in compared to K702 but it makes up for it in instrument separation. It has an unusual signature in that it has a prominent bass, neutral mids (or recessed with pleather pads), but a spiked up low treble that makes it both dark and bright at the same time.
They don't have very much in common at all and are almost opposites.
