Query: What bass?

I do not understand how they have the nerve to put anything about "good bass" in the technical and product descriptions for this item. I got these to replace my Koss Sparkplug earphones, and what a disappointment! My old Sparkplugs have pretty darn good bass response, but they are kind of a hassle to get into the ear. When I first put in these Koss KEB24 earbuds I was *ecstatic* over how well they fit into my ears and how easy they are to put in. I thought: man, with such a good fit these are sure bound to sound great! Wrong. Once I tried listening to some bass-heavy mp3s--big letdown! If you want good bass--stay away! Even with the lousy fit the Sparkplugs had much better bass. I'm new to this type of earbud so I'll have to keep searching for something better.
