One of the best fitness trackers available in the Apple Watch. Even if you aren’t interested in the health-related capabilities, this wearable is capable of much more. If your iPhone’s battery runs out, for example, you can still listen to Spotify or Apple Music on your Apple Watch. This makes the watch an ideal partner for going for a jog without having to take your phone with you.
You may use it to track your outdoor workout and listen to music while you’re out and about. You’re probably thinking to yourself, “How do I attach my earphones to this tiny screen?” The technique is the same whether you want to pair small Bluetooth earphones or a huge speaker to your Apple Watch. Here are the steps to turning your Apple Watch into your own personal DJ.
How to pair Bluetooth earbuds to the Apple Watch
Turn on the pairing mode on your headphones or earbuds. The exact procedure varies according to the model, but in general, you must press and hold the power button for six to ten seconds until the status light begins to flash. For more information, consult the user guide that came with your headphones.
Open the Settings app on your Apple Watch by pressing the Digital Crown.

Tap “Bluetooth.”

When the headphones appear in the list of devices on the Bluetooth tab, tap them. If you don’t see them, make sure your headphones are in Pairing mode and that Bluetooth is turned on on the Apple Watch’s bottom screen (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.
When my iPhone is running low on battery and I’m on the go, I always use this feature. This allows me to save the battery on my phone for things that the Apple Watch can’t handle. It’s also worth noting that if you have AirPods, pairing them with your iPhone immediately connects them to your Apple Watch. As a result, this method can only be used to pair non-Apple Bluetooth earphones with the Apple Watch. It’s also useful if you want to leave your iPhone at home because your Apple Watch can manage both music and fitness tracking without requiring you to carry your phone around in your pocket.
