good headphones, but not drastic improvement over lower-end models

Summary: I originally purchased these headphones as an upgrade over E2C, the selling point being that these were advertised to have "extended bass" with "tuned-port technology." However the low end difference between these and E2C is not even noticeable. The only improvement is the clarity of the higher freq. Another drawback is that these earbuds are smaller, and as such, are more difficult to stay in place.
Summary: I was hopping an impressive experience with this earphones in my MP3 player, but it wasn't. They give a superior quality in high frequencies, the sound is very clear, but in low frequencies I felt a low quality, a "litle empty bass", definitively lower than the standard earphones of my Zen Micro. With the E4G you can perceive more clearly the sound and others sound you haven't hear before. The external sounds isolating feature, uhmmm, not too good.
