For those who are wondering about the tuning, here are the measurements:
Default tuning is typically Grado with the midrange honk around 2khz - but these do have a bit better bass extension than some of the other models.
With Geekria Pads:
In general, the tuning isn’t for me, but they do remind me of the Sennheiser HD800s in some respects - like the shifted upper mid to lower treble kind of balance. They also have a decent soundstage on them. So, not my kind of thing but I can understand why someone might like this. Those who are treble sensitive should probably look elsewhere though.
