Applying the same logic to cell phone headsets, a normal headset (one that goes on one ear) is a mono headset with only one streaming line of audio. You have one ear, one speaker, and one line for audio. A stereo bluetooth headset will cover both ears and split the audio into a left and right channel for sound.
