Yes. Anything that interferes with your ability to pay attention to keeping the tonnes of metal you’re driving on the road, is dangerous. It’s a distraction and stops you from being able to hear audio cues like sirens, crossing signals, etc. Horns are also not entirely “fuck you” buttons but to warn other drivers of potential hazards, through sound. Use your cars sound system. Buy a shitty dongle if you have to; but headphones of any variety is a bad idea for driving. It’s also illegal in some jurisdictions.
