There are two types of dual-device connections for our soundcore C40i earbuds. Understanding these options will help you make the most of your listening experience across multiple devices.
Type 1 (for other earbuds):
With both your phone and computer connected to the earbuds, the earbuds will play audio from whichever device starts playback first without letting the second device cut in. For example, if your computer starts playing music first, the earbuds will continue to play from the computer even if your phone starts playing audio later.
Type 2 (for soundcore C40i):
With both your phone and computer connected to the earbuds, the earbuds will play audio from the device that starts playback last. For example, if your computer starts playing music first and then your phone starts playing audio, the earbuds will switch to the phone and pause the computer's audio.
Note: Due to compatibility issues, notification sounds may be mistaken as audio and can override the playback.
