Anyways, coming to the point, it is not a good idea to listen to music from head phones, ear buds or any other in ear devices while riding. This does not allow you to listen to the traffic, horn from other vehicles etc. and may pose a risk to your life. Listening to music from external speakers would be ok but does make one look like a chapri. Nowadays there are many options available like bluetooth enabled speakers etc. Even scooters like ola are equipped with speakers to listen to music while riding.
Hope this helps.
Cheers
