Removing the Ear Cups

1. Place the headphones on a table and while holding the ear cup with one hand gently and slowly insert the tip of the screwdriver between the ear cup and headphones.
2. Once inserted gently twist the screwdriver until there is a slight separation between the ear cup and the headphones. Note: Do not twist the screwdriver too much as this may damage the headphones.
3. Continue step 1 and 2 moving the screwdriver until there is gap between the cup and the headphones all the around the cup.

Installing the New ear Cups

1. Hold the ear cups tightly with one hand while holding the headphones with the other and gently pull until the cup is completely separated. Note that some headphones may have more adhesive than others so more pressure might be required to remove the ear cup. 
2. Find the replacement ear cup that matches the side removed (they are labeled L and R inside the cup). Align the letter in the cup so that it is legible with the bar at the top.
3. Gently press the ear cup into place ensure that the pins remain aligned.
4. Once there is a slight click sound press more firmly to set the ear cup into place.

To re-establish the functionality of the Advanced Swipe Controls (details in the image below), first update the My JBL Headphones app in the Google Play/App Store.
After the installation is completed, pair the earbuds to your phone/tablet through Bluetooth and open the app.
The earbuds will be detected and displayed in the app and you should see that a Firmware update is available.


Note: Advanced touch controls are deactivated by default, in the My JBL Headphones app go to Settings  once your earbuds are displayed, then select Gestures and enable Advanced Swipe Controls. You can now select each function and assign it to a specific gesture.
