FAQ:
Sound Quality:
- Headphone products often require a period of use to achieve better sound quality. Components like transistors, integrated circuits, and capacitors are initially unstable in electrical parameters and stabilize after a period of use.
Volume Synchronization:
- The earbuds are primarily compatible with mainstream mobile phones (iPhone, Samsung, etc.). Due to the variety of Android systems, they may not be able to adapt to all computers or Android devices. If volume cannot be synchronized, adjust it manually from your phone or computer.
Call Clarity:
- When making phone calls, turn the volume to the maximum to avoid issues in noisy environments (e.g., subways, buses), which can affect signal connection and stability.

- Warranty: 18-month limited warranty.
