Before you can do that, though, you’ll need to connect your watch to Bluetooth headphones or earbuds.
Check out the products mentioned in this article:
1. Put your headphones or earbuds in pairing mode. The specific method varies depending upon what model you own, but generally you simply need to press and hold the power button for six to ten seconds until the status light starts flashing. Refer to your headphones user guide for details.
2. On your Apple Watch, press the Digital Crown and start the Settings app.
3. Tap “Bluetooth.”
4. In the list of devices on the Bluetooth page, tap the headphones when they appear. If you don’t see them, make sure your headphones are still in Pairing mode, and make sure Bluetooth is turned on at the bottom of the screen on the Apple Watch (swipe the button to the right if needed).
The headphones should pair automatically and you’ll be ready to listen to audio through your Apple Watch.
