The Ferrari 4005 uses the Realtek ALC250 Audio Codec.

The Realtek ALC250 integrates a 50mW/20Ohm headset audio amplifier into the CODEC. Single chip with high S/N ratio (100 dB)

I don't what ohms are and impendence rating do. Does anybody know what rating [ohms, dB] headphones I should use to get the Loudest Volume Possible from the Ferrari 4005 headphone jack?

I know these ratings play a role in volume but I don't know how.

Currently I am using so Philips Noise Cancelling Headphones rated at:

Frequency range: 40 - 20,000Hz
Impedance: 45 ohms
Sensitivity: 102dB
