I still question the generalization about "Chinese people."  For one thing, maybe I am a Chinese person - who finds it useful to have a clock.   Actually, true.
 
I didn't say anywhere that anyone should buy a DAP based on a clock.  I just added that it that it could use a clock and a scroll bar to make it more useful.  For some reason, people have fixated on the clock comment.
 
In any case, I think i will stop now.

 
 
what would you suggest then? maybe I should generalize on a broader scale, or on the contrary - make it more specific? come on dude, how do you think I could express the idea without that generalizing element that seems to be so unsettling to you?
 
 
back to the topic:
 
could everyone be so kind as to do the following regarding the hissing issue:
state if you hear or not hear hiss, what phones you are using and at what gain level and what volume is the dap set at. for example:

person A: I can hear hiss at low gain with my Ety er4 at volume 236. I can not detect any hiss on medium and high gains on MAX volume levels)
person B: I can not hear any hiss with any of my phones on any gain and volume levels
person C: I can hear distinctive hiss on low gain at 200 with ety er4.
 
this would help us a bit to see if there is difference among the units with the same phones. of course it doesn't consider variables like persons ability to detect hiss, the state of earphones etc but would still be something tangible.

I hear hiss at low gain with my JH163A FP at all volumes, amount of hiss does not change respective to the volume. I hear a bit less hiss in mid and high gain.

@sensui123 - personally, if I pay for a product I expect it work.
 
I don't feel that after experiencing the long string of various features not working on my first run through, its overly harsh to compare the operating system to the level of bugs that a beta system has. If you buy a product - it should work ! end of
 
I would have been more than happy to help them iron out bugs through feedback if they asked or made it clear the system wasn't finalised.
 
Having said that, they have been brilliant at releasing 2 x firmware updates in a [week?] I really appreciate that.
 
I bought the Cowon x7 when it first came out - I had 4 separate units in a row that bricked. Cowon didn't seem to care - I think it was something like 6-8 months later when a firmware update came out. I don't know if that fixed it as I didn't want to hold onto a unit for what [would have been] 6 months to wait for a firmware update
 
Anyway- good job iBasso at the flow of rapid firmwares updates but maybe next time...be honest / communicate

Received my DX50 via DHL earlier today. I'm pleasantly surprised to find a full charge on the device. As for the sound (15 minutes in), the jury is still out! I'm coming from a Studio-V 3rd Anv Ed, so I'm not really sure what to think yet, but at least there is NO hiss and the UI is performing functionally atm with V1.1.5.

The reactions you received had everything to do with your "Dumb" comment directed at iBasso. Nothing more, nothing less.

  yeah, that's what I hear also, inherent hiss without anything playing.  AKA typical of sensitive IEMs on amps with certain noise floors.  It's nothing that distracts me while listening to music, but I can tell it's there when nothing's playing.

 
Do you hear hiss using the Line-Out to any of your amps? That would more than likely answer your question. 

 
I haven't experienced any hiss with any of the IEMs I've tried: W4R, H-200, 1p2, SE5, RE-400

So far I haven't heard any hiss from mine, but I'll give it a thorough check with my bunch of iems tomorrow

No hiss there when I tried with O2, Pico Power, and Pico Slim amps thus far.  I am going to assume this is normal as the TG334 is just too sensitive I guess.

Im not having ANY hiss issues, I havent heard any hiss at all. (although an mp3 will not be seen on my own dx50 - Im only playing 24/96 and some flac 16/44 lossless) .Im sorry to say you may well have a faulty unit? It would be easier if we could physically compare!  Also Im listening through Grado gr10's which are super sensitive.
 Sometimes with a very high quality unit / headphones a lot more is revealed than one may be used to. but it doesnt sound good - you shouldn't be noticing anything but blissful music...so i would return it
hope that helps?

 
 

  you should be able to hear hissing when the music is paused, not when playing, because every music can have some hiss in it. just listen to some old recordings of jazz or whatever it may be for that matter...
 
 
Hope mine doesn't have any hiss on the max listening volume I can endure to listen. if it is so, it's good.
 
also, be sure t update the firmware - the hiss might be caused by some bug in certain cases....

 
 

Do you hear the hiss when there are no music playing? If you do, I get that too. I'm not convinced a change of player will help so I'm looking for other DX50s in my area to try before requesting for an exchange.

 
This thread is moving entirely too fast.  I go do some work and its 4 pages in.  Anyways, I know that some records may have some hiss but that is not the case. I hear the his when the unit is on, but no music is playing.  As for the hiss when music is playing, I feel like its still there.  It just seems like I have the gain too high using another player or amp or whatever.  Its not to the point where its unbearable but it is a little bit annoying after coming from my desktop setup's black background. 
 
that said it is less than the Studio V which sounded great but the hiss was just too much.
 
@tak, please update us if you get a hold of another DX50 and the hiss is not there. Thanks

  Now pause the music and listen to it (I know, weird) can you detect any hiss? usually human ears are unable to detect hiss when playing music, so you need to pause it to hear any hiss that it has.

 

[Sorensiim]

Even weirder: Load a file with nothing but silence. Some players will mute the output when the music is paused, thus concealing any hiss. Playing a silent file will reveal this.

Sorry, but how did the DX50 not work?  As I mentioned, it played/scanned almost all of my music just fine and the only files it had trouble with were some with funky characters in filename/tag (and appeared to do so for everyone else I can see except a few that had funky tags/other issues).   Sure it had some features missing in terms of sorting and playback that are being added right now.  The whole update thing using the coaxial/lock to navigate is overblown as you can just reboot the player and try updating again and it'd automatically go through the update itself (I tried this myself).   I'm not sure what your idea of a beta OS is as I'm quite experienced with that developing OS environments in my programming days but the release firmware is a far stretch to be called as such.  You are right, you pay for a product expecting it to work but I don't see where they weren't honest and stated everything was flawless and 100% in their UI.  They delivered what they promised IMO, but I guess everyone has different standards.
