How come it seems that the sound quality is no good?

Buds Pro sound quality is tuned based on a large number of user experiences, and the sound quality is at the top level in the industry. However, there may be differences in the user experience of sound quality for different users. We recommend that you download the Nothing X App. Open the Equaliser page in the app to select preset sound effects. Alternatively, you can use Custom to adjust the sound according to your personal preferences.
