How to pair Bluetooth headphones with your Apple WatchTo listen to audio from your Apple Watch, you'll have to pair it with a Bluetooth headset.

If you want to listen to your music (or any other audio) you've synced with Apple Watch, or Apple Music streaming on Series 3 watches, you'll need to pair your watch with some wireless headphones.
