Greetings francesco_disco,
Thanks for visiting the Apple Support Communities! It seems you're curious if you can use an audio-input device in the headphone jack on your 2017 MacBook Air.
The 3.5 mm audio jack doesn't support audio-input on the MacBook Air: Identify the ports on your Mac - Apple Support
"Audio
Use Audio-Out — 
or 
— with headphones, speakers, and other audio-output devices that connect using an audio cable that has a 3.5 mm (1/8 inch) audio jack. On 14-inch and 16-inch MacBook Pro models with Apple silicon, you can connect high-impedance headphones to the 3.5mm audio jack.

with a microphone or other audio-input device that connects using an audio cable that has a 3.5 mm (1/8 inch) audio jack."
Kind regards.
