Bluetooth connected but music will not play

Hi

The following steps may help:

If you have not yet done so, then update your iPhone and Apple Watch to the latest software, starting with your iPhone:

• Update the iOS on your iPhone, iPad, or iPod touch - Apple Support
• Update your Apple Watch - Apple Support

Unpair your compatible* headphones from your iPhone or from any other device that they may already be paired with.

Restart your Apple Watch:

• Restart your Apple Watch - Apple Support

Try moving your Apple Watch and headphones to a different location, further away from any other active Bluetooth devices:

• Potential sources of Wi-Fi and Bluetooth interference - Apple Support

Enable and disable Airplane Mode on your Apple Watch:

• Put Apple Watch in Airplane Mode

Re-pair your headphones with your Apple Watch:

• Use Bluetooth accessories with Apple Watch - Apple Support

* Compatibility

Most - but not all - Bluetooth headphones that use the A2DP Bluetooth profile can be used with Apple Watch for listening to music from it:

• Listen to music on your Apple Watch - Apple Support
• Use Bluetooth accessories with Apple Watch - Apple Support

Apple does not publish a list of compatible headphones.

Headphones that are least likely to be compatible are those that also offer additional built-in functions such as fitness tracking, a heart rate monitor and/or a built-in media player.

For any such headphones, I suggest that you check with the manufacturer regarding compatibility.
