Inserting your earphones Individual AR earphones are designed specifically for either the left or right side. Make sure you find the left (L) or right (R) marking on the inside of each earphone so you know which side is which. Make sure the sleeves cover the end of the earphone stems. Finally, gently insert your earphones in each ear, just far enough that they fit securely—do not push beyond the ear canal opening! Note: Once you’ve put on your earphones, use the cord adjuster to increase or decrease the amount of slack in the cord. These earphones come with the small sleeves installed. If these don’t fit the way you want them to, try a different size—the next section tells you how to change sleeves. Choosing and changing sleeves Experiment with the different sizes in this package to find the right sleeves for you. Changing the sleeves is easy. 1. To remove the sleeve on the earphone, pull gently on one sides of the sleeve at the base of the stem until the sleeve comes off. 2. Position the replacement sleeve at a slight downward angle over the earphone stem. Gently push the sleeve up and onto the stem until it fits securely in place. 3. Push the end of the sleeve gently to make sure it covers the stem completely. Connecting to your audio device 1. Turn the volume of your audio device all the way down. 2.
