Bose QuietComfort Headphones | Too little bass or too much treble from product

If the sound lacks bass or has too much treble:

Try the following:

Check the equalizer settings in the Bose Music app.

Be sure the bass and treble adjustments are not set too high or too low for your preferences. For more info, see Using the Equalizer settings .

Adjust bass and treble controls on the source.

Sound quality may suffer if bass and treble controls are set to extreme levels. Try adjusting the controls to mid-range levels; this may improve sound quality. Be sure to turn off both audio enhancements and special equalizer settings found on the source

Try connecting a different audio device.

If available, connect another audio device using the same cables and connections to determine if the issue is related to the first device or its settings.

Try a different app.

If the issue only occurs with a particular app, it is likely related to the app or app settings.

Be sure the headphone openings are clean and free of debris.

Check for blockages in the headphone mesh grille and headphone opening. Excessive debris can result in low audio, poor sound quality or missing audio channels.

If connected, bypass any adapters or extension cables.

If your product connects to the device using an extension cable or adapter, disconnect the extension cable or adapter to determine if the issue is related to it.
