I have owned my ES 10 about 2 month
For the Scratch we can do anything, i carrying with the original Pouch and the cable it self i put in a little Pouch , that the Jack not scratch the Headphone
and i put very carefully in Hypo Travel Hard Case.
I am agree the ES 10 sound better with Amp, for Portable Amp i use Stepdance 1.
Sound Character :
Bass : very Big volume Bass and Tight for Travel Headphone
Mid : Sweet sounding Mid
High : is open but still neet bright Amp to get more open like with my Stepdance 1
Source : Iphone 4 with WAV File Music
LOD : Silver SCSAG Cable to mini Jack
Note : You can directly hear from your Ipod or Iphone too, but with NOITE your music File MUST WAV, to have good
Sound from your Iphone . The Volume is CLOSE to MAX can sound very good too.
