With Custom Equaliser (EQ), you can use sliders to adjust five different frequency bands and save your preferred settings. You can also pick one of the presets, like 'Heavy bass' for a starting point. These settings do not apply to phone call audio.
Important: If you're using Google Pixel Buds, you will only see Bass Boost. If you are using Pixel Buds A-Series, you can customise your bass.
