Fix for BOSE headphone problem
I've just learned of a useful fix for the problem of Bose headphones not connecting to an iPhone, which I'm sharing in case it can help others dealing with this issue. Since purchasing the new iPhone 13, I haven't been able to connect my Bose QuietComfort 35 II headphones to the phone until today. To fix the problem, slide the ON-OFF button on the headphones toward the Bluetooth icon and hold it there for 10 seconds. That will clear the previous Bluetooth Device List and then Bose QC35 II will appear as a discoverable device on the iPhone.
