There is too much bass in my headphones

Many portable audio devices have a bass-boost switch to electronically alter audio signals sent to the headphone jack. Your headphones have patented technology that reproduces a full range of sound, so there's no need to use a bass-boost feature or other tone controls. For the best audio performance, disable bass boost on your portable audio device. Leaving bass boost on may result in exaggerated bass and potential distortion.
