Query: Incredibly awful sound quality

My standards for sound quality aren't that high, but the sound through these headphones is so unbelievably horrible that I can't use them. The sound is extremely quiet, tinny, and has no bass. The sound is equally bad through all of my music devices, and changing equalizer settings does nothing. These may be cheap and relatively comfortable, but I wish I'd spent a few more dollars to get something better. I'll go back to my less comfortable iPod earbuds.
