If the earbuds slip out during use, the most likely cause is an ear tip size mismatch. A few quick adjustments usually solve this.

1. Try other ear tip sizes. If one earbud doesn't feel secure, try mixing sizes (e.g., medium for the left ear, large for the right).

2. Twist the earbuds to find the best position. Run the Fit Test on the soundcore app to ensure a proper fit.

3. If the above steps do not resolve your issue, please contact customer service for assistance.
