How can I transfer music to my Amazfit T-Rex 3?

You can transfer MP3 music files to your watch by opening the Zepp app and navigating to Profile, then selecting the Amazfit T-Rex 3 and the Music page. To complete the transfer, your phone must connect to the watch's temporary Wi-Fi hotspot. Once the files are moved, you can listen to local music by pairing Bluetooth headphones directly to the watch.
