To reduce spring tension in the headset, hold each eartube at the bend near the eartips and 
gradually pull apart until fully extended (180 degrees).

 

To increase spring tension, grasp the headset with one hand where the metal eartubes 
enter the plastic tubing, and squeeze until the plastic tubing on one eartube touches the other. 
Repeat as necessary.
