Hi, is it possible to divert the audio outpt on my 2017 accord touring to a 3.5mm audio jack instead of the car's speakers?

 

sure, it's possible. but you should not drive headphones directly. You can run the front output to a LOC then into a headphone amplifier.

If you had 300ohm headphones, then maybe you could drive them directly.

In most states it is illegal to drive with headphones.
