- Multi-Device Connectivity: The specifications do not explicitly mention support for connecting to two devices simultaneously (multi-point connectivity). If you need to switch between devices, disconnect from the current device before connecting to a new one.
- Ergonomic Fit: The earbuds are designed for comfort. Experiment with different ear tip sizes (if provided, though not explicitly listed in package contents, it's a common accessory) to find the best fit for stable wear and optimal sound.
