For at home I have on-ear headphones from Bose (very fine), and so the Creative EP 630 were intended more as a bridging solution for the road until I got time for money "right" in-ear earphones. So, for the good, expensive. The good for something. What I have everything trial heard of Sennheiser, AKG, Sony, etc., and nothing came in sound (and bass!) The Creative EP 630 close. At least not as close to justify a price difference of 30, 80 or even 230 euros (these Sony high-end parts for 250 Euro).
Sometime I've seen then: these things are just great. The suck. They're worth more than 18 euros. I need do nothing More expensive. And since I had this revelation, I live a lot more relaxed. :-)
