Headset Adjustment and Sizing
The headset should fit comfortably over the head and ears without pinching or gapping. A comfortable fit is conducive to
effective and pleasant use.
To adjust the headband size, do the following:
1. With the headset resting securely on the top of the head, slide the ear shell up and down to center the ear cup over
the ear.
2. Swivel the ear shell left or right to position the ear cup straight on the ear.
