I stuck an audio book on (what I listen to most in terms of pure hours) in a demo with the standard sound system and like most lofi systems, at default settings, male voices become really bassy (especially bad on Radio 4 in a morning!) and so you have to tune out the bass. Then when you put music on it sounds lame so you have to dial it back in again ... but keep it quiet
Like everything else though - it's horse's for courses and one man's "sounds shit" is another man's "wow that's nice". Which is cool because it's an optional extra
