Which ear cushion should I use?
Your H15 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.
The ear cushion is fitted onto the end of your headset’s earpiece speaker like shown, and placed onto your ear when using your headset.
When fitting an oval-shaped ear cushion on your headset, be sure the cushion is oriented, as shown below (pointing towards the microphone).
