Query: Overall sound quality sacrificed for base quality

Most inexpensive products like this have tradeoffs, and the ones here with these earbuds were obvious the instant I put them on. All of the mid- to high level tones come out very muddled and distant-sounding, but the base tones are clear and powerful. So much so that fiddling with the EQ can't improve the upper levels, and don't manage to make the low levels any worse. On the other hand, they are pretty comfortable.
