【Notes for Bluetooth earphone users】
When using Bluetooth earphones or certain external audio devices, the minimum volume step and adjustment range may vary depending on the device specifications.
Even if you adjust the volume in 1% increments within the app, the connected device may not support such fine adjustments and may follow the same step size as the iPhone system volume.
This behavior is due to the characteristics of Bluetooth technology. Thank you for your understanding.
