Here are some steps you can try:
- Ensure your iPhone's software is up to date. Sometimes, software updates fix compatibility issues. Go to Settings > General > Software Update to check for updates.
- Sometimes, Bluetooth devices don't show up if their battery level is too low. Ensure your JBL headphones are charged adequately before attempting to pair.
- Reset the headphones by turning them off, then hold the power button for 10-15 seconds until you see an LED blink or hear a sound indicating a reset. Then try to pair again.
- Confirm that your JBL Tune 760NC headphones are indeed compatible with the iPhone 15 Pro Max. Check the JBL website or manual for compatibility information.
- Some Bluetooth devices have different methods for pairing. Check the JBL Tune 760NC manual for any specific pairing instructions and try different methods if available.
- If none of the above steps work, it might be beneficial to contact JBL's customer support. They might have specific troubleshooting steps or be aware of any known issues.
Remember to ensure your JBL headphones are in pairing mode when attempting to connect them to your iPhone. The exact steps to enter pairing mode might differ, so consulting the JBL Tune 760NC manual can be helpful.
