Headphones need only little power to punch your eardrums, the difference is
not significant. I measured 77 mA with zero volume, 80 mA at full blast (you
would not want to have wear that), with a low-impedance headphone (sortof the
worst case).

I recommend setting the volume to 93, this is 0dB and gives an unaltered 1:1
signal, no attenution, no amplification. Use less if you have to, but you
lose SNR (Signal to Noise Ratio).
