Thank you guys I have try the 1.9.5 with rockbox, it's great, can create own EQ with specify band however when I tried to save the eq, after typing the name, what do I press? Anyway since this issue and also the trouble of navigating with unknown icons, I revert back to doc v3, by far is doc v3...

Sorry but Im an idiot, I am still using doc v3 and fw 1.2.9 (Is this right? Or I need to update official fw to 1.5.0), do I need to change anything as of 2023 Sep? Do I need this rockbox thingy? I just want it to sound as good as possible, I know it is subjective, but this current setup works...

  I will be trying out  2) FLAC-only + irr ON + CPU 312kHz --- closer, more intimate and clearer imaging with little more separation in width. First.   Thank you for your answer! It relief me a lot hahahaha..

What is HP Cable? The usb cable? I was switching it on and off without any cable.   I assume by your reply this is normal but why 1.6 does not have this ticking sound? Hmm..   Just a little concern as I am not sure if I am doing everything correctly lol.

  Erm, with refer to page 961, I am manage to get into the new setting menu. I guess I am successfully flashed the fw.   The question now would be, what is with the ticking sound when booting up and shutting down? It comes directly from the player, not the IEM.

Hi all,   I had recently bought a new DX50 and match with a TDK IE800 for myself as a belated bday present. :) It both works amazingly.   As I was browsing through the this thread, I came across SU 1.3.3 and so, I browse all the pages and finally found the link to it. I do it normally...
