Nevertheless, I was intrigued by what I heard and got this crazy idea - I could do a 3-way flagship custom IEM review and sell all my universal IEM; leaving me with a pair of customs for home listening, a pair to take out in public with me, with a spare pair in case I lose one or the other pair.
I also very much liked the ES3X with the iPhone 3G and iPhone 3GS headphone-out, where an amp is not needed at all.
The UE11Pro are very efficient like the ES3X, so just about any amp allows them to play as loud as you can stand.
With unamped iPods, the UE11Pro bass is usually less well controlled, but UE11Pro actually sounds better with the 5.5G iPod video headphone output vs the iPhone 3G and 3GS which I often prefer over my 4G Nano headphone out.
As with the ES3X, the JH13Pro sound good enough to use with the iPhone 3GS and no amp, and they also make my 5.5G iPod video sound great. All of the customs actually make the headphone out of the 5.5G ipod video useable again to me. I was also very pleased
