Sound quality - DAC ??

I am considering switching from the SGS2 to the X. The sound quality while listening to MP3's on the S2 was average at best even with tampering with all the settings etc.
What is the quality of the sound like on the X ? Anyone know what DAC is inside ? I have a set of Shure E535's and want to make best use of them. If the quality is the same as the SGS2 i think i will use the bit i have saved and buy a Cowan Z2 and keep the SGS2.
Thanks for any advice

I'm interested in this myself. I've already ordered the phone though, as I need a new one.
I'm hoping I finally can put away my mp3-player, but I guess it will still be some years until a phone reach Cowon sound quality. :--/

The original Samsung Galaxy S and any other device with a Wolfson DAC came close, with Supercurios Voodoo app. Best sound on a mobile device! But SamsUng dropped the Wolfson for a Yahama DAC on the SGS2! Wonder what DAC the HOX has!

i'm no mod, but i already made a thread about this.

i don't think a phone is ever going to include good audio. the amount of people that actually use expensive headphones and lossless files are too small for the companies to care. i sold my Cowon D3 because they messed up trying to use Android 2.2 with insufficient hardware. i'm looking at the S9, J3, or X7 now. i'll use the beats audio eq bs until i have the spare 250-280.

My good ol' Sony Ericsson w950 had a fantastic sound quality!

As a user of an iPhone with high end multidriver in ear monitors (Westone UM3x and Shure SE420) sound quality ranks very high in my list.
Thus i would appreciate if some owner of multidriver iems could chime in with an opinion on the headphone out sound quality. With all effects turned off. If the audio hardware is any good (low output impedance, low distorsion and low crosstalk) the sound should be very good (Just as it is off the iPhone headphone out) and no need of audio tweaking would be necessary.

On every iPhone/iPod I've tried since their inception the DAC hasn't been the talking point, and flaked out when the eq is modified, even with a decent pair (sennys/shures) of 'phones.
I think buying a phone to replace a (good/non-ipod) portable player is a bad idea.
It's also entirely subjective; you could have a Cowon S9 and top-end in-ear sound-cancelling headphones, but if you're listening to 192kbps CBR mp3s you may as well be using your phone and a pair of £20 Porta-Pros - in most situations the source is the bottleneck, then the headphones, then the DAC. (IMO, of course)

I just asked for an opinion from a high end iem user about the HTC One X headphone out. Honestly I don't need your view on portable audio. But thanks for enlightening me.
Parameters like the impedance output impedance are nothing but subjective. iPhones output impedance is lower than 2 so they will always get a linear signal to your multidriver iem where a high z source like the galaxy S2 will get a pretty skewed signal that will ruin the frequency response of the iems.
Sound and electricty are sciences even if some people find it hard to believe and prefer esoteric approaches to the matter (That's specially true amongst Cowon fans

There is way more to those 3 factors for sound quality, plenty of things have those but don't sound good.
Anyways for most multidriver IEMs to make the most out of the IEM you will want some sort of amperage, even my Cowon C2 isn't powerful enough to make some IEMs shine (power doesn't always need to equal volume, but power to drive with authority)
My Soundaudio Rocco-P however, at the same volume, blows the Cowon out of the water, and there was a time you could of gotten it only for $1 + shipping on head-fi
But the SGS > SGS2 that is IMO but neither hold a candle to the C2 or the Rocco.
To the OP the cowon is a fine DAC but if you just need music playback (and if you need FLAC) there might be better options in your budget
I'm still looking for portable setup that doesn't involve carrying a brick around that will power my modded Fostex T50RP

First of all, many ipods and the iphones sound great, their EQ sucks but their SQ is quite good, really good if you pass the headphone out, and use the line out into an amp via a LOD.
They are not the end all of players though.
Porta pros are amazing IMO, they are one of my fav headphones under $100

Any update on DAC? Audio Quality?

Personally waiting for GSM Arena to do their audio test. Below from The Verge's review:
AUDIO
Audio quality on the One X is superb across the board. The earpiece offers clear, loud calls, and the rear-mounted loudspeaker does as well — for whatever reason, HTC's managed to make this placement of the loudspeaker work far better than Samsung did with the Galaxy Nexus, which produces exceptionally quiet, easy-to-muffle sound. Callers reported that I was easy to hear even in significant background noise and wind, a good sign that this phone's dual-mic noise canceling system is really well tuned.
The 3.5mm headphone jack outputs clean, noise-free music — clean enough that I was easily able to pick out the depressingly low bitrate of Rdio's tracks. Of course, the One X carries the Beats Audio branding, as most HTC devices are now expected to (HTC owns 51 percent of Beats, after all). I find it ironic that the One series' tagline is "Amazing Camera, Authentic Sound" when Beats' audio processing is anything but authentic — in fact, if anything, it intentionally diverges from the artist's intentions. Every time I hear music with Beats enabled, it just sounds like bass boost to me, which is a trick we've seen in various forms in portable audio products for at least 30 years.
I'm not saying some users don't appreciate Beats — it definitely makes music more "exciting" sounding — but if you're looking for "authentic" music reproduction, Beats definitely isn't the answer. Personally, I'll be leaving it turned off. And fortunately, it's easily toggled either from Settings or from the notification tray while music is playing. It should also be noted that Sense 4.0 (and Sense 3.6 as found on HTC's Android 4.0 upgrades for older devices) makes Beats processing compatible with any audio app, which is a big improvement; previously, it only worked with HTC's baked-in apps.

Now that a few people are receiving their One X's can anyone answer my question please

Yeah its just music playback i want if i have to get another device. What do you think of the Cowon J3 ??

I agree nikzDHD about waiting for the GSM Arena review. I read the Verge review earlier and it sounds good though i would prefer a more detailed review on the subject.

Honestly, I wouldn't trust the verge's gsmarena's or most other techsite's for their "audio quality" reviews.
just FYI. having fancy bar charts, graphs etc isn't the end all, having someone be able to compare it to another device, with tons of experience, using high end audio gear is MUCH more important.
Unfortunately phones usually don't get tested in audiophile type things and you are better at looking at audiophile forums and seeing if experienced members have used them.
I'm just saying for SQ, cowon isn't the best there is, but their EQ system is one of the best, but EQ can't replace energy, soundstage, or detail reproduction, all it does is emphasize certain regions of the sound changing the "sound signature" like I said my RoCoo P is superior to the Cowon but is far cheaper, but the UI sucks, and it's missing features, but I use it almost every day when I need to walk somewhere.
I suggest reading here: http://www.head-fi.org/f/15/portable-source-gear then after reading through there potentially asking your question there, but please do list your headphones, source type, type of music, and if you *need* eq or not.
It all depends on your budget and how large of a device you want to carry. I can recommend things like the ibasso DX100 or hifiman HM-801 which are basically almost as good as you can get in a portable audio player, but they cost more than a new phone, and they are very bulky.

um.. no disrespect/no intended banter to the above poster
but we simply just want to find out if the audio quality is sufficient for use of mp3s
in comparison to say the S2, which everyone knows has disappointing sound quality . Yes we all know the S1 had a good DAC etc, this thread is more so about the phones sound quality and not about how much of an audiophile we are etc.
I need to know as if it's good enough, I don't have to bring my Cowon J3 with me everyday to work as well : )

I can't recommend the sansa clip enough. Cheap, good battery, flac support and even better with a portable amp! One of the best sounding players I've had.

What is "sufficient"? What is "good enough"? It varies for different people.
If you want to know if it plays music, yes it'll play mp3s. If it's good enough to you or not, I can't say.
I can tell you this, in terms of SQ I'd rank what I've used as this SGS2 << SGS1 < rockboxed Sansa Clip/fuse (first gen) < Rockboxed earlier ipod < Cowon players < RoCoo P
This is of course FLAC, if we add mp3 playback I'd say the iphone/ipod touch fits in better than the SGS1 but can = sansa clip/fuse
These are also only what I'd consider portable DAPs.
The OP wanted to know if they should keep the SGS2 and get a J3 or get a one X instead and was focused on audio quality.
I just happened to say I think he could get better than the J3 for better SQ for the money. I'm just trying to help the OP.

Most people just want to carry one device, I've also got a rockboxed Sansa Clip its small enough to take anywhere and sound quality is very good. Again to OP Sansa Clip is the cheapest way of getting some good sound but good sound is only good if you pair it up with a good set of headphones to take advantage of it.
If only Supercurio lived in the UK I would of let him borrow my phone his analysis is very good.

I have a Sansa clip+ lying in a box that i haven't used in a long time and just rockboxed it. Teamed with my Shure E535's and a few flac albums this little guy sounds heads and shoulders above my SGS2. Actually shocked how such a small player can sound so good. Going to get a portable amp and this will save me a few quids. Many thanks for the replies

nice! Yeah a rockboxed clip+ is definately the way to go for small awesome sound. They are also basically impossible to beat at the price you can get a clip+ and fuze for
if you want my help, let me know how much you want to spend on an amp and i'll point you in the right direction
But basically in terms of portable (and affordable amps) ibasso, jds labs and fiio (if you get their higher end stuff)
Good luck with your search, hopefully you can find a good amp that pairs well with the 535's

Audio tweaks when root is achieved.

So, I'm a little underwhelmed by the DAC on this phone. It's mainly the volume. My Note 2 with DAC tuning and V4A sounds much better and is much louder.
Assuming we get root, will we be able to tweak the audio down to the DAC level in terms of oversampling, tuning, etc? Would we just be stuck with V4A and other software based optimizations?
Ideally, I'd like a louder headphone jack that doesn't suffer from as much distortion when turned up. My main issue is that it just isn't loud enough for me.
I'm using Klipsch S4's and ATH-M50s. I do plan on adding a pair of RHA IEM's or another pair of full size cans.
I know that people are using external amplifiers successfully with the phone, but I'd rather not carry one around if I could squeeze more power out of the DAC post-root.
Thanks!

I think it would depend on whether its done at the kernel level or at the chip layer (either from a soft processor or actually part of the HDL code fabric). Then again I no know nothing about audio DACs so it might make sense for them to expose those level of hooks to the kernal or even software/rom layer since they're often times needing to be tuned to a speaker's performance for achieving a desired sound (hopefully).
If this fails maybe it might be worth adding a outside box DAC from Fiio (those are good, I have the same headphones, ATH-M50s, and they do improve the sound even with v4a especially if you're seeking higher audio volumnes) or maybe even an USB Audio DAC (I would suspect these are even better than analog <> DAC <> analog ones) which will newly be supported natively by Android L and maybe already by Samsung phones.
http://www.androidpolice.com/2014/0...-android-now-natively-supports-usb-audio-out/
Hope that might help, unfortunately I doubt we'll see the level of tuning capability that you're seeking. I don't really know much about qualcomm's audio DAC selection but those with exynos phones I know have those really nice premium ones. It's all up to the hardware's capability and for all we know qualcomm's DAC has some crappy sampling rates which will never be able to be improved on if you're looking for good audio directly out of the jack.

Thank you, definitely helps. The audio output on this phone did get some good numbers according to GSMarena. I'm hoping that it means further tuning is possible. I believe the HTC One has a crazy 2w audio jack that's both loud and clear and also utilizes the same DAC. Hopefully that's a good sign for the possibility of tuning on this phone.
I was considering a Fiio box. I just hate having to carry that thing around or keep it clipped somewhere. The native USB audio out in Android L sounds promising though. I'd assume that a smaller USB sized box would leave a little less of a footprint.
I think Samsung actually ended up losing a lawsuit due to hearing loss. I suspect that it may be a reason why the audio output on the Note 4 is intentionally crippled. Hopefully I'm right and hopefully it's reversible.
I miss the Wolfson DAC on my Note 2. That thing sounded incredible. I'm tempted to sell this and seek the Exynos version just for the audio output.
When you use your m50s directly from the audio jack and through v4a, are the volume and distortion levels and better when cranking it up?
Oh, I also think that a file exists on the phone that limits the decibel output on the headphone jack. It can be altered to a level of 63 vs the 56(ish) that it's currently set at. I remember doing this on my Note 2 and it helped with high volume distortion quite a bit.
Root, we need you root.

[Q] Behringer UCA202 DAC - sounds horrible compared to headphone jack/bluetooth

So I found a Behringer UCA202 DAC online for really cheap and thought why not try it just for fun. Everything I've read says having one can help a bit and I figured at the least it would sound the same, but I plugged it into my Nexus 5 via OTG then plugged the AUX cord to my Jeep into the DAC and all bass and pretty much any other level of detail is gone from my music whether it's from Pandora, YouTube HD, or FLAC audio files. Audio sound quality is equal to listening to music over old mono bluetooth, you hear it fine but any highs and lows are removed. Has anyone else used this DAC that could give some suggestions?
Otherwise it's just as I assumed, DACs are pointless on good quality phones and that's why I can't find any DAC threads with the Nexus 5 involved.

Yes it has a DAC but it's not meant as a stand alone DAC. It's an interface or soundcard. Does your phone have enough juice to even operate the thing? Also for a device that sells for less than 30 bucks what exactly where you expecting? Get a real DAC. You will notice a huge difference. Until then do some more research on what you have and see if your meeting it's power requirements.
This is actually a pretty good review of the unit with lots of technical info.

While I can't see power being an issue I suppose I'll test with my Nexus 7 and laptop. I know it's a cheap DAC but I've read many reviews using this DAC with tablets and phones for car audio, along with the nwavguy in-depth review and testing showing how it's not a multi-hundred dollar unit but still does amazingly well. My issue is it doesn't even sound decent. It sounds like I'm playing rap/hip-hop through an old Nokia on speaker phone, you can hear it clearly but there's no depth.

So I tossed this DAC in a closet after I got bored of trying to make it work right and forgot about it for a year or so till earlier today when I found it while cleaning. My Nexus 5 has been retired and serves no purpose other than a security camera now. I now have a Samsung Galaxy S5 and an RCA Maven Pro tablet. The RCA Maven Pro is an 11.1inch 2-in-1 Android tablet with detachable keyboard for around $120. You'd assume it's horrible thanks to the brand and price but they managed to cut corners in all the right places it seems. Downsides are no GPS, 1GB of RAM, terrible cameras, and a horrible speaker. Other than that it has faithfully replaced my $1200 laptop with zero issues other than adjusting to ditching Windows.
Now back on track when I listen to music I'm either using an aux cord plugged into my work truck or bluetooth when using headphones or in my new car. When doing a side by side comparison bluetooth, to no surprise, shows no difference between my Maven and S5. However when using an aux cord the RCA doesn't put out as much bass and highs are... I guess not as clear? I think audiophiles are insane most of the time so it's hard for me to describe when I do notice a difference. Anyways I plugged the UCA202 into the RCA's USB port (no OTG here, it has a full size USB port) and plugged my Sony MDR-XB950BT headphones in to it with an aux cord (these headphones are 100% passive when wired, no bass boost or other enhancements) and sound quality is just as great as my S5, all bass and highs are restored. Just to further the test I plugged it into my S5 and did the same test with the same results. These are the same FLAC song files from the same network location that my Nexus 5 was playing a year ago.
The whole time the issue was something in my Nexus 5. What it was I don't know and sorry you guys I don't plan on investigating, I just wanted to inform everyone that the Behringer UCA202 is in fact a quality budget DAC since this thread is a top Google result for "Behringer UCA202 Android". If you have a cheap device that you want the audio to be on par with the high end phones this will do it, and for my original purpose of at the same time giving a bit of amplification for a weak head unit without distortion it does that decently too. To finish this off I am NOT an audiophile. Just a human with human hearing that likes songs with bass on car head units that weren't always designed for it (I glued a 80mm CPU fan to the back of the HU in my Jeep ) So take my finer details however you'd like.

the DAC works great for my Nexus 7 2013 model.

maybe otg cable is sh1tty

DAC quality? (headphone audio)

Guys What is your opinion about the headphone audio quality from op3? I know audio is subjective and it depends upon your listening equipment too but nonetheless share your opinion.
P.S - I know it's not better than HTC 10 but comparison with HTC 10 would be a good reference.

I'll be getting one too, so I'll report about it. Unfortunately there aren't many, if any USB-C Portable DAC, if you wanted to use one to boost audio quality/performance.

I'm also wondering the same thing and it's basically what's holding me from buying the phone.

It uses NXP Audio Amplifier. I had the review unit and did a teardown with one of my friends. The sound quality is Good via the headphone jack but it feels quite flat. You can fix this by Using V4A Or other EQs. It uses a Dirac HD Sound too.

As said, it uses the standard snapdragon 820 audio circuit and 24bit 192 kHz built in dac. As in the S7, audio is unexceptional (exynos version has wolfson derived Dac and is better but is said to still not be up to outboard Dac/amplifier quality).
Apps like viper and power amp will not help to increase sound quality. They may make things sound different but the limitations are hardware based. If anything, they put more strain on resources. Sure, if the pretty multi coloured lights appeal, use them. Otherwise you're better off with Google standard music player or something like black player.
If audio is of utmost importance go HTC/LG or outboard dac such as dragon fly.

[DISCUSSION] Headphone Jack performance

I wanted to start a thread discussing the performance of the headphone jack. I'm a bit disappointed considering Sony's audiophile history with their walkmans and LDAC codec.
Yes, I'm nit picking about a $13XX dollar phone but for this price, I was expecting a bit more that just average performance.
For comparison I do have a LG V40 with it's quad dac and it powers my audio technicas perfectly fine with High-Impedance mode.
On the MK ii, I don't get the full sound with out an external dac coming into play.
I'd like to ask other MK ii owners if having just a headphone jack is enough to power your earbuds/iems/headphones.
Going to do a bit more in detail research within a couple of days but I think Sony just wanted to slap a headphone jack just to say it has one.
Ps- I'm no audiophile but having a full sound for the headphones I have is a must.

Thank you! This thread is very interesting.
I have reduced hearing and I badly need a smartphone with high-output. My LG V30 with it's QUAD-DAC has no problem giving me enough volume even on my favourite pair Hifiman HE-4xx.
I was hoping that Sony 1 mk2 was an alternative, but maybe not................ ?

Ps- I'm no audiophile but having a full sound for the headphones I have is a must.

You may want to make the distinction between headphone jacks that can and cannot drive high impedance headphones as a headphone jack that can't can still be good as in clear, little to no distortion with good response and sound reproduction.
In this case its more like LG's has gone out of their way to include a dac that can power high impedance headphones (which is rare in the first place, in addition to the jack being rare) so if high impedance headphones usage is a top priority, then sticking to LG would be recommended.

I have a Meizu Pro usb dac which has a good reputation. The volume of the Meizu is a bit higher, but the audio quality of the Sony is equal. You just have to increase the volume 2 or 3 notches. The Sony uses the Qualcom dac and excellent Cirrus amplifier chips. I use my Beoplay H6 over the ear headphones for listening. The volume being a bit lower is no problem for me, I still can get serious hearing damage if I want to.
The audio is detailed, excellent channel separation, noise is undetectable.

Yeah LG has done the headphone jack justice, but I was expecting a bit more out of the mark 2 for it's price point.
Like hi-res audio. I get it's mainly a photography oriented product. I mean I guess I got used to only using half of the volume steps provided by the LG phones.
I just had high expectations out of Sony in the audio department. Great camera. As for the dac mentioned above, i have a couple so I'm not too worried about getting any more of them. I have a couple of headphone I can try out besides my audio technicas.

The audio capability of the phone is lacking
Bluetooth volume is pretty poor even though it's decent quality
The 3.5mm Jack absolutely doesn't have that much power to drive much more than basic iem 8 to 16 ohm level. Can't push my 150ohm cans at all

Definitely louder than the previous phones. I'm just happy that the jack is back. I did notice a difference with bluetooth vs wired on WH1000XM4. Volume was definitely louder on bluetooth, but can really notice the difference in quality despite LDAC. But that's just me.

But it does have Hi-Res audio. Volume is a bit lower, but is also the curve of the volume control. With the LG the volume control is linear, with the Sony starts to increase real slow, until over half of the volume.

Yeah volume has to be over half way to start making decent sound. Regular buds are fine though. I have some kz iems and it's fine with those. Just higher impedance isn't for this phone.

My Beoplay H6 headphones have an impedance of 30 Ohms. They work great with the Sony. I can't compare, these are the only wired headphones I have.

The audio quality is perfect with my XBA-N3AP or WH1000XM3

Oh snap, how are the XBAs?
Currently, I'm using AKG N700nc2( using them wired )

XBA are amazing, well balanced and no extra bass like many earphones.
With an upgraded cable it's even better [emoji106]

I think using its headphone jack to push N3AP do not working perfect, the human voice is low, the sound ‘s analysis goes bad, compare to use usb-3.5 dac line. I use IE60.

Poor volume, I can still get hearing damage by the levels of volume here.

I haven't tried with a dac, I will try to compare with my XA50ES

Apologies for replying to an old threat, but what became of this? The link is now dead unfortunately. Was it an actual improvement or deleted because it was non-functional? Thanks.

Try to dm peter. I didn't have a chance to save this.

Sony Xperia 1 II most probably uses a Qualcomm audio codec. Can be their flagship Aqstic WCD9341, a dedicated audio chip. Only a proper tear-down will reveal the details. As I found out this audio chip contains a very good DAC section and can produce nearly 1 Vrms at headphone out when implemented in high performance mode.
