It is especially noticeable if one listens to "modern" vs older CDs vs the radio. I suppose Producers now feel compelled to exercise subwoofers and thump the audience, or compensate for crappy earbuds in the target audience, or maybe that's just what people want because even radio commercials are complicit -- it's difficult to listen to someone talk with "thump/thump/thump" drumbeats in the background. Often, I simply turn it off.
In my car, I have the bass response dialed back by about 50%, and even dip the mid-range by about 15% to get what sounds to my ears like a flat response.
I have mild hearing loss from the 250 to 1k range, so my ears are already attenuating the signal -- I can only imagine how "bass heavy" it must sound to someone with normal hearing!
