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.

A Goodyear welt is stitched to the upper and a strip of canvas (known as gemming) which is cemented to the insole of a shoe as an attach-point for the sole.he upper part of the shoe is shaped over the last and fastened on by sewing a leather, linen or synthetic strip (also known as the welt) to the inner and upper sole. As well as using a welt, a thread is used to hold the material firmly together. The welt forms a cavity which is then filled with a cork material.
