If you're not particular about using an equalizer, you're better off with the Pistons 2. But for under $10, the 3580 remains king along with the Monoprice 8320. I'm thankful for the 3580. It taught me how to equalize. When I first got my 3580, I honestly thought it was just above average. But when I started to play around with the equalizer, I was dumbfounded at what you could do. Hence, I include a pair's receptiveness to EQing when judging them. Admittedly though, not many earphones are receptive to EQing, so for me the 3580 is special in a way because could easily "bend" it to fit most tastes.
