Caution - bus users

I went into town today on the bus pass special, a journey where no one is of an age where they need to pay. One elderly gentleman sitting in front of me took out his phone and very carefully inserted his wireless earbuds. He began to scroll through his music collection and after a few minutes he selected a song. He then proceeded to play that track, and several others, at full volume to the rest of the bus. I was tempted to explain, and help him set up, the wireless part but I suspect I'd have needed a longer bus journey.
