You don’t need any of the expensive solutions you might have read around. You just need a cheap splitter cable (”cavo sdoppiatore”) that costs about a couple bucks.

This way you can plug a regular mic into one female jack and a regular headphone in the other.
Bonus OMG-I-AM-LATE-FOR-TOMORROW’S-DEMO: Just use the mic of a bluetooth headset. (un auricolare bluetooth)
