Wearing your headset
See figure 3 on page 2 
The ear cushion is fitted onto the end of your headset’s earpiece speaker and 
placed onto your ear when using your headset.
Your H780 headset is supplied with multiple ear cushions. Your headset’s 
performance is greatly dependent upon achieving a good fit on your ear. 
Therefore, we recommend trying all the supplied ear cushions with your 
headset.
You can wear your H780 headset on your left or right ear. The headset comes 
ready for the right ear.
