May have found a partial solution for anyone not getting enough power to some headphones.
Happened to plug in a 3.5mm extender since a couple pair of my headphones' connectors are too wide or shallow to make good contact through the otterbox. Plus I thought leaving the extender connected while I swapped headphones might save some wear n tear on the V10's jack:

Plugged in the extender first by itself and the dac switched on but went into aux mode:
Then I plugged the headphones into the extender but the V10 stayed in aux mode.
Tried it anyway and good news is aux mode's output power is somewhere between normal and high. Was able to get more volume to the headphones but not sure if the sound signature is affected.
Not sure how different this "method" is compared to using an impedance adapter (adapter likely the better choice) but those who already have a regular extender (even a 3.5mm extension cable might work) can try it for themselves.
Also, if you plug the headphones to the extender first then connect to the phone, the V10 detects the headphones as designed. I did this using my mk3s but when changing headphones at the extender end (I left the extender plugged into the phone) the dac stayed on and in high impedance mode (my PM-3s sounded incredible with it). Even when I turned the dac off with the extender still plugged in it remained on high when I switched it back on.
EDIT: I also confirmed that high impedance mode is NOT compatible with cable buttons. ANY headphone directly connected to the V10 with an in-line mic/remote cable will cause it to default to normal power. I confirmed this with the mk3, hd598, and portapro vs. ktc version. The mk3 and hd598 are barely usable at normal due to low volume and all (even the portapros) have more dynamic range in high power.
CONFIRMED. Have a male - male 3.5mm for an AUX input in my car. If you connect via headphone -⤑ Female-Male 3.5mm-⤑ V10. It will stay in AUX high gain mode. Cheers
