I got a pair of e3000 from Amazon. It sounds pretty nice and perfect fit for the price. I did some research and found e3000 was designed to present more bass than e2000 and e2000 has more clear highs than e3000.
Al3mbicI have both E3000, and E2000...While they don't differ too much in sound signature, you might notice that E2000 has more mid bass impact, which may feel as more bass overall, depending on your music preference. E3000 on the other has less impact, but extends deeper into sub-bass. So in my opinion, E3000 has better quality bass, and E2000 feels as more quantity.
