Beyerdynamic dt 770 pro 32, 80, 250 ohm all versions need 100 mW power. In this case, how is it easier to drive 32 ohm headphones than 80 or 250?

if the audio interface audio output has a constant voltage ; 32 ohm dt 770 pro, uses much more amperage ( 'i' ) than 80ohm or 250 ohm dt 770 pros. Same output but not same power. This is okay.

İf the voltage can vary :

These examples: 1) Audient id 4 MK2 headphone output : 30 ohm - 2.59VPeak, 1.827V RMS, 223mW ----- 62 ohm - 4,18 Vpeak, 2,95 V RMS, 280mW ! Voltage can vary. !

2)
''1.37 second. '' For example : Motu m2.

How 16 ohm into power more less than 32 ohm into?
