I realize most people don't listen in mono unless it's an accident.  Such as;  listening to a mix in a different room or listening from a distance. 

or listening through a phone's in-built speaker
 
my teenage kids' most common method i reckon
 

LynnI have my main monitors in the center of my room, so one trick I use is to stand behind them and listen in stereo.  This helps to pick out parts that don't sound quite the same when listening direct, as well as hearing volume levels between parts.

i would surely never bother mixing a song with the intent of someone listening on phones!
hehh
you can't make any serious decisions listening on a playback system like that,
so why focus on it?

i don't know anyone that listens to music in mono.

Some “audiophiles” regard headphones as the “purest” and only truly acceptable way to listen to recorded music. They often seem to be under the impression that’s how mixes and mastering are done.....

It's funny, but people of different ages listen on different monitors.  I perceive that older people listen on speakers, while younger people listen on ear buds more often.
