Headphones on a bike are illegal in my province. So I once bought a bluetooth speaker for my bike. I don't really like imposing my music to anyone and tried to keep it at a minimum level but stills didn't like it. So now I use bone conduction headphones. Unfortunately they are also in a grey area where they could also be illegal.

In short, if you want to listen to music on a bike here, your only legal option is a speaker. Anything else is unsafe and could traumatize a poor car driver that hits a cyclist that didn't hear them coming (according to the police here).

Otherwise get a car and blast the music with the windows open like a normal safe person. or close the windows and don't hear anything around, but this is much safer than having headphones while cycling, obviously.

Same with walking or jogging with headphones. Are you out of your mind? Some poor car driver could hit reckless runners jumping in front of their car because they couldn't hear it coming.

No, society wants everyone not in a car to keep quiet and don't ruin their silence, with all the soothing car noises, so it's safer this way. No headphones on a bike, it's not safe! You need to hear that car blasting music that's coming at you.

There’s some shithead in my area that lugs around one of those large JBL party-size looking Bluetooth speakers and has a habit of sitting at the bus stop across the street from my apartment and blasting his shitty rap music for the whole fucking neighborhood to suffer. Always super awesome to finish a long night shift, crawl into bed, and be woken up to that shit a few hours later.

Get the cheap corded earbuds and wrap em around a rock for aerodynamics.

My favourite is people blasting shitty music from the speakers on their Harley's, fucking double trouble
