RESET NETWORK SETTINGS

Should you experience connection dropouts that cannot be resolved by a soft reset or by deleting the headphones from the device's Bluetooth memory, you can try a more drastic approach and reset your network settings:
Go to Settings --> General --> Reset --> Reset Network Settings.
This is the third option, where you will avoid resetting all settings and deleting all content and settings! Be careful here :-)
By choosing "Reset Network Settings", you keep your data intact, while your Bluetooth/Wireless connections will revert to their default settings.
