How to connect my Bose wireless headphones to my iPad?

In your Bose headphones press and hold the power button to set the headphones in pairing mode you should see a led turning on red/ blue then get your iPad closer go to settings/bluetooth if you se the headphones tap over then to pair that’s all

Ozzie's information is correct if your headphone support Bluetooth as I believe all current and recent Bose headphones do. But if you have an older set, yours may not. Confirm the specifications of your headphones with Bose.
