For those of you who are interested, I used RMAA and my M-Audio Firewire 410 audio interface to record and analyze the following:
 
- Samsung Nexus S with Voodoo Sound
- HTC One X LTE with sound processing off
- HTC One X LTE with Beats audio on (headphone set to Other)
 
I used supercurio's new app that plays a RMAA test signal to do this. Also, I repeated each test twice to verify that my results were accurate.
 
Note that on the One X, the output level doesn't go beyond -10dB when volume is at maximum, so I adjusted the Nexus S to -10 dB, even though it can go higher.
 
I have no idea if my methodology is sound, but I'd say the frequency response speaks for itself.

Here are new results obtained with a Native Instruments Komplete Audio 6 USB audio interface that I purchased. They are more in line with what we should expect, and very close to the results obtained for the One S by GMSArena. Don't ask me why the difference, but since my M-Audio Firewire audio interface died shortly after the last measurements, I'll assume there was a problem with it.

This new diagram is completely different from the previous one and much more in sync with the one shown at GSMArena indeed.. so could it be that people are imagining the One X to be bad when it should be around average?

 

[knights]

gsmarena means of measurement is flawed in the first place.

Question: Could the sound of the HTC One X change (read: improve) drastically through use of a portable amp?

One X vs Galaxy S III:
 
Just an update for those who might be debating between the North American versions of One X LTE and the Galaxy S III LTE, both of which use the same Snapdragon S4 CPU and are different from their international counterparts.
 
I just received a new S III today and ran it through the same RMAA test. Basically, results are the same as the One X, except that the frequency response does not exhibit the "ripples" that wee see on the One X. However, because their amplitude is so low, these aren't audible anyway and IMHO the difference is irrelevant.
 
In terms of sound quality, they are nearly identical. After a short session of A/B comparisons , here's what I can make out:
 
- Volume levels are higher on the S III, which might be of benefit to some of you.
 
- However, hiss is also noticeably louder on the Galaxy S III. While the hiss is audible but not terribly bothersome to me on the One X, it is frankly obtrusive on the Galaxy S III. This is only with IEMs and during quiet passages, with larger less-sensitive cans, I don't hear hiss with either.
 
- Overall, the One X sounds a little cleaner.
 
In the end, to me, the hiss with IEMs is a deal-breaker as far as the S3 is concerned. For those in North America who are stuck with S4 versions of these phones, I believe the HTC One X is superior as a DAP if you use sensitive IEMs (again, this is irrelevant to the international versions).

Im wondering the exactlly the same thing... Just got my international One X yesterday and ordered a Fiio E11 too.
 
Im now reading about the sub-par DAC and wondering if I hook up the amp if that would still provide that extra SQ Im after?
 
I have also just seen that people are using an external DAC with a USB - minUSB converter on the Galaxy SIII... Would it be possible to do this on the One X?
 
Will be using a pair of ATH WS55s btw

 

[DoomForce]

So.. noone knows if the audio quality of the HTC One X can be improved some way?

 

[crabnebula]

If we had control over analog gain on the headphone jack like Voodoo Sound provides on the Galaxy S series, that would be very helpful. I know some devices had this added into their kernel by developers (eg, Nook Color), but I have no idea if it can be done with this phone.

 

[Chefano]

Im really interested in the AT&T version, does anybody know how it compares (SQ)  against Iphone 4 (I have an Iphone 4 32GB, but its so damaged and Im tired of the tinny screen).
 
Thanks!

You guys rightly confused me now...
 
I'm in the UK and I'm thinking about getting the HTC One X next month, and now I'm getting this Galaxy S3 Vs. One X debate.
 
In terms of looks usability the HTC wins for me but now, I'm I don't know what to think about the sounds quality.
 
I currently use my HTC Desire for cycling and DAP so, help?

Just curious about why you want the One X over the superior S3?
 
(for reference I've owned both and spend part of my time reviewing mobile devices, presently own an international S3 and US-variant, and used a One X as my daily driver for about 8 weeks before that)

So, what does have the best SQ? 
The AT&T One X or the S3 International.

 

[Vladimir_F1]

SGS3 waaaaayy better than One X. 

Actually One X sounds like a 10 $ phone.
 
I've listened to both of them. 'Beats Audio' is marketing trick.

I can't compare to the AT&T One X directly, only the International S3 and the US S3 (which has the same DAC as the US One X). For my money the International S3 sports better SQ than it's US variant brethren. Besides that it also supports USB audio, will have even better SQ yet once Voodoo Sound (finally!) arrives, and all-round is a much, much better device.

 

[JohnerH]

For some reason in my mind I thought in terms of hardware the One X was better equiped.
 
I'll have to revisit my choice once I'm up for a new phone next month.
