Bass and Treble Adjustments Have Little or No Effect?

Possible Cause:

The current EQ preset may limit or override the effect of custom gain adjustments.

Solutions:
1. Open the Ultimea app and switch to Custom EQ mode.
2. Use the 10-band equalizer to fine-tune the sound to your preference.
3. Alternatively, select a preset EQ mode and then adjust the bass, midrange, or treble gain, if supported by that mode.
