It will function, but I suspect that it won't be optimal sonically, and conceivably also in terms of the peak volume levels that can be reached cleanly (which may be an especially significant consideration for well recorded minimally compressed classical symphonic music).
The relevant specs on the headphones are:
Impedance: 50 ohms
SPL: 112 db (1 kHz, 1 Vrms)
Those are fine. However, the specs on the C162 headphone output are:
"Phones: 100 ohms" (it's not clear if that means output impedance, or recommended load impedance, or minimum recommended load impedance).
"Phones: 190 mv into 8 ohms" (it's not clear why they are specifying output into 8 ohms if the output impedance or recommended load impedance is 100 ohms or greater).
Regardless of how the 100 ohm figure is interpreted, it suggests that driving 50 ohm headphones with the C162 will not be optimal sonically. Although the degree of compromise MIGHT be small, depending on how the impedance of the phones and the output impedance of the preamp's headphone output vary as a function of frequency.
