- 在两个设备上保持 OnePlayer 都处于打开状态，并且不要熄屏
- 可以在手机端边听歌边传输，可以使传输更稳定
- 确保手表电池电量充足
- 如果不着急，音频传输可以在后台进行，但传输完成时机不可控，完全由系统决定

MP3, M4A, AAC, M4B, WAV, AIF, AIFF, AU, CAF, FLAC
⚠️ Some high-bitrate FLAC format files are not playable on the watch.
Audio transfers should start within a minute, if they don't progress then do the following:
- Keep OnePlayer open on both devices and do not turn off the screen
- You can listen to music while transmitting on your mobile phone, which can make the transmission more stable.
- Ensure the watch battery isn't low
- If you are not in a hurry, the audio transfer can be done in the background, but the timing of the transfer completion is uncontrollable and is entirely determined by the system
Place the watch and iPhone on charge to speed up transfers.
