Here's a tip) Library update can't read revised tag in X3. It only can read first-saved tag.... So, if you revised your mp3 tag, which saved in sd card already, you must take out the sd card. And do the lib update. Next, put it again and do the lib update once more.

If you say so, I think my X3 was not perfectly tuned before. Because I disagreed with this opinion; 'X3 is warm'. My X3 was very sharp and cold. In Aviator 2.0, my X3's bass was not strong. Rather, it was bass-less. However, now, I can agree with X3's sound is warm. I think firmware 1.23 revised...

to James. I have a question. Is there some sound tuning in firmware 1.23? I can feel more bass than fore firmware version. If it is, I think you must instruct at firmware download page. Thank you for reading and I expect your answer.

I think that bass was increased approximately two steps in EQ . I'm not sure, however, in my ears, it is.

to x3 users. Did you check new firmware 1.23? I think bass is stronger than older version. You can download from fiio's official homepage.

I really want 'scroll bar' and 'jumping function' to the next scroll in track list.... Can it be revised?

Does someone has Fidelio X1 and Fiio X3 both? I will appreciate if you explain the sound. I'm really curious about these X-brothers' sound

If there is no sibilance in x3.... I use aurvana live now, and I think Aurvana causes sibilance.... Or my song exaggerated vocal, may be. I'm sorry for the confusion

I use x3 now. If x3's sibilant is reduced, it will be better. Can it be tuned?

Hi James I use X3 now and its sound is very good. However, there are some inconvenient points. I am poor at english, so I hope your generosity. 1. Jump to the next scroll page in track list. 2.Choose back button's function- former page or upper root 3. In folder browser, support gapless/...
