Query: poor sound quality

I just got the M9394G iPod earbuds as a gift, and I think the sound qualitly is awful. The two-year old earbuds that I got with my iPod originally sound better than this $40 pair. I originally thought I may have gotten a defective pair and returned them at the Apple store for a new pair but these too sounded like an old radio. Very tinny with no bass.
