You can broadcast your media so friends and family can listen with you. To join, your listeners need Auracast™ (LE Audio) compatible headphones, earbuds, or hearing aids.
While you are broadcasting, you control the master volume and playback directly from your phone. Individual listeners can adjust their own volume on their respective Auracast device.

If you have Auracast™-compatible headphones, earbuds, or hearing aids, you can connect with another person's phone and listen along with them:
Select the broadcast name and, if required, enter the password.
You’ll hear the broadcast. You can adjust the volume on your device without affecting the broadcast’s volume for others.
