# Fitting your EPOC X

Before fitting the headset onto your participant, you must choose if you want to have the headband at the top or the rear of their head.

To adjust the headband, hold the arm and push the headband up or down to rotate. The headband will lock into place. To readjust the headband, repeat this process. 

When you rotate the headband, update the settings in your chosen EMOTIV application so that the motion data can be interpreted correctly. 

For further information on adjusting the sensors, refer to your EMOTIV application guide.<br>
