You should have no problems with paralleling 2 headphones on the
audio output of the K3, with no need for any external mixer.
I would not risk it. The K3 headphone amplifier is only rated for
105 mW at 16 Ohms. Both power dissipation (heat) and distortion
rise significantly as the load impedance drops and the output power
increase.
I had this problem when installing a FTM-10 in my Mazda Miata. I
placed the speakers in series so as not to overload the audio
amplifiers. The output level is somewhat marginal when traveling
at freeway speeds with the top down, but so is conversation with
a passenger.
