Too much bass or too little treble from product | Bose QuietComfort Headphones
If the sound lacks treble or has too much bass:
Try the following:
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 a different app.
If the issue only occurs with a particular app, it is likely related to the app or app settings.
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.
