just had my VB for a couple of days .. with 20 hrs of burn-in. the most noticable aspect of VB is its deep and controlled bass. a good amount of bass quantity with a great bass quality.   the mids and the treble is quite good for sub $100, fresh out of the box i was dissapointed by a lot of sibilants and quite harsh treble but after 20hrs of burn-in process i can notice the sibilants and hars treble reduced a bit .. so i think another 100++ hrs of burn-in should do the trick
