Query: Weak bass, highs ok but not impressive - not worth money paid.

I paid $15, relatively low in terms of Hi-Fi earbuds. If Coby can sell "Super Bass" models on Amazon at around $5 or $6 which perform quite well, I don't see why this earbud should have been such a weak performer. These earbuds are some of the most poorly performing I have seen (at the price). Bass output is way down from that of the actual recorded music I am listening to.
