Headphone breathing anxiety?

Basically when I have my headphones on I like to have the volume around 60-75% full. When I have my headphones I fear that I'm breathing too loudly and that people will hear me breathing loud and be like "why's this guy breathing so loud?". by the way this is on public transport. Anyone else feel the same way and can offer a solution? Apart from just not listening to music.
