If your headphones will not connect your Bose app, try the following suggestions:
Turn the headphones off then back on again
Close the Bose app on your device and swipe it away to fully close it. Then reopen the app and try to connect again
If your headphones are charging, remove the charging cable. The headphones will not connect to the app while charging
