Well, in that case we're going to have a problem, if Oratory measures the regular Nighthawk only with the hybrid pads.
The results simply won't be applicable to the Nighthawk Carbon.
And we all know how much different pads can affect the FR.
The serious method would be to measure a headphone (Nighthawk or Nighthawk Carbon, doesn't matter as they are identical) with the three sets of pads : hybrid, all-leather and velour. Then we would have results that would work for everybody.
@jaco61 , I guess you have no way of providing alternate sets of pads to Oratory ?
