These are not V-shaped by any definition. They have a bit of a hump at 1k and no hump or peak in the treble. They’re neutral/warm, but with a dip at 3-4k that moves the vocals a bit farther out than what you have in HD6x0-series Sennheisers or other vocal-centric headphones. But V-shaped these are not, they just don’t have the treble to be called V-shaped. And with the perforated pads they just get a touch more airy and smoother, closer to neutral and even further away from V-shaped.

I don’t understand why M0N is calling these V-shaped, where he’s getting all of that treble that would form the right side of the V.
