I have never used IEM before and now I want one because of its isolation. And I don't want to use AMP because there is no enough space for both ipod touch and a portable amp. If ipod touch cannot drive these two, I will consider IEMs with less impedance.

I have the Re0's and the iPod Touch drives it decently, if you listen to your music really loud then it won't be enough, but it will drive it to decent listening volumes. I bought a Fiio E5 to help a little and it added just enough volume for me

The RE0s from the Ipod Touch isn't loud enough for you?  That's crazy, a little over half way is normal listening volume for me, anything past that and it's quickly making you deaf.  I'm using the "3rd gen" 8gig ipod touch...

Well in a quiet environment it's plenty, but being on the road in a bus, or in a subway or something for example, it's not loud enough. Also I have the 2nd gen so maybe it's a little different?

Maybe it is because you use different tips. Thanks for your reply. I will use IEM in buses.
 
And by the way, 3rd gen 8gig ipod touch is the same as 2nd gen.
