@m17xr2b your review pushed me over the edge... wallet open 

I have only listened to the 3.1 on portable systems, although Heinz did mention that the 3.1 might be the better choice on some big tube setups because of its damping factor.
About high clamping force of the MYSPHERE head-bow:
m17xr2b is correct in mentioning that the subjective high clamping force will be reduced by time. It's a certain process of getting used to. Especially for those who are used to normal headphones.
But also true is, that for bigger heads the clamping force can be high.
This is why we changed the material of the metal-bow towards a flatter force displacement diagram. This enable for small heads almost the same force as normal, but for larger heads 30% less force.
All MYSPHERE's shipped since mid of April has this new metal bow part and stronger fixation of the sound-frames into the bow as well.
The older head-bows can be bent up to a certain extend. But it has to be done with care. A bending is only in the upper middle section allowed. Not at the two edges, it would cause damages there!

Hi,
Thank you @hrklg01 for this explanation since it is true that I have noticed for a too soft clamping an increased aeriality, not good for immersion.
These MySphere 3.2 really have a superior sound stage, very accurate mediums (oboe more natural than my Susvara) and a big resolution.
For me, the biggest problem is that I have a DAC + Tube amp very performing in the low frequencies range and listening to Symphonies the MySphere on those low frequencies (dark movements) saturates heavily where headphones like Abyss, LCD4 or Susvara are in heaven.
Not a question of power at all (sensibility to too much power), really a frequency saturation (below 100Hz ?).
So you're saying it's entirely the amp's fault and not the Mysphere suffering from dynamic compression due to large membrane excursions reaching their limit? On the other hand it would be understandable that a completely open design like this, with minimal baffle dimensions against phase cancellation, could get into troubles at extremely low frequencies. After all that's how one could interpret cladane's «saturation».In deed for some amps it's not easy to drive the MYSPHERE 3 at frequencies below 100Hz.
