I can tell you know that after a couple days of use the comfort has increased and I can wear them multiple hours (that's all that is safe for my ears) and the bass has smoothed out and I can hear the highs and mid sections more clearly.
It even says from vmoda themselves "burn in=the fit IS the sound, like new shoes, your headphones will sound their best after the ear cushions, headband, and drivers naturally adjust"
These are one of the only headphones I've heard improvement from only 48 hours of burn in. Anyways I really like them. Mom says they look cyborg. Lol.
Congrats for the buy!
