You calculate the needed voltage.
Then the tricky part starts if headphones have a varying resistance.
For Sundara it is easy as it is resistive.
For the M50X it is also as good as resistive so currents are easily calculated.
For headphones with wildly varying impedances calculating the current is tricky as that will vary er frequency.
There is another catch though. When the amp section is current limited then, at the moment there is not enough current the voltage also will not reach the desired value.
This is what this makes a bit more complicated because the maximum voltage is not only determined by the voltage limit but also by the impedance.
But for Sundara this is not frequency dependent.
