Setup

Connecting the Earbuds

Locate the 3.5mm audio jack on your device (smartphone, tablet, laptop, etc.).
Insert the 3.5mm connector of the earbuds firmly into your device's audio jack.
Ensure the connection is secure for optimal audio quality.

Selecting Ear Cushions

The earbuds come with small, medium, and large ear cushions. Choose the size that provides a comfortable and secure fit, as this significantly impacts sound quality and noise isolation.

Gently remove the pre-installed ear cushions.
Select a different size and carefully push it onto the earbud nozzle until it is securely attached.
Test the fit and sound quality. A good fit will create a seal in your ear canal, enhancing bass and noise isolation.
