For our complete illustrated fitment guide, refer to the User Manual. Here are a few key steps to remember when putting on your headset: 1. Inspect the ear seals (the pads that rest against your head) for damage before use. 2. While wearing, make sure that the ear seals rest against your skull without sitting on any part of your ear. 3. The microphone should be no more than 1/8″ from your mouth. 4. Adjust the headband or soft strap for a comfortable, gentle fit across the crown of your head. It’s normal to feel a bit of pressure when you wear the headset properly. The seal protects you from dangerous noise levels.
