Thanks for measuring these.
It killed my curiosity a bit as the 5% 2nd harmonic distortion at 4kHz is a bit much, this seems to be a driver problem (or enclosure ?)
Maybe I am wrong and modding brings out the best in them.
The peak around 7kHz seems to be reducible (quite easily I might add) but wonder if that were done mechanically (felt of sorts) if that would reduce the adjacent band as well.
The whole 'treble' area seems to be verging on 'trouble' judging from the CSD.
Maybe it isn't as bad in reality though.
As shipping these things from the USA costs more than the whole headphone itself I will skip this one (unless it becomes available in Europe) but am told they are not going to sell these in Europe.
