So, mono audio?

Mono audio generally means having one channel of sound, whether you are using one speaker or ten to play that one channel.

You can have Stereo audio just come through one ear. It doesn't mean the amount of headphones it comes out of, it's whether the sound is a mono channel or a Stereo channel.

No, if you mix down a stereo signal to one channel it becomes mono audio. If you then send that channel to 2 headphones or speakers it's still a mono signal; ie you get the same signal in both ears.
