Yes, sure, volume and eq, are almost the same, thanks.
I insist, i expected a HUGE difference between a Samsung phone and a X3 player...
Now i think that my Samsung with a E10 or E 18 will be much pristine than this X3...., or i'm crazy..??
If you're looking for HUGE differences you've choosed the wrong hobby
Fwiw I got a new phone yesterday (Z3 Compact)and on request is did A/B comparison between it and my old M7 but choosed to put the X3 in the mix as well. It's all in the Z3 thread but the short short version is that I found the X3 clearly superior two those pretty well regarded (soundwise) phones.
I tested primarily with the Fidelio X2 and the ATH-CKR10 which are both easy to drive but pretty revealing.
Maybe you've just set your expectations to high.......
