LG V20 Sound Quality
Sep 25, 2017 at 7:31 PM Post #2,926 of 4,139
I will, for sure. I don't think that V20 is a steal, there are just way too many small compromises in term of pure smartphone experience (waterproofing, battery life, size, camera, LG boot loop issues that could creep up out of nowhere...). But, take into account audio and it quickly not only becomes a good deal but an only option (ok, next to HTC 10 and about 3 times more expensive V30).
I am with you when it comes to trusting life style audio brands, however, B&O does make some nice products if value is of no concern. What I am trying to say is, they have the knowledge and I can't really see them ruining the hardware of V20.
Even after saying this, I will definitely aim for the non-branded V20.

I came from a Samsung S5 to the LG v20...so in every way the smartphone features and capabilities are just so much more usable and better in the LG V20 (except waterpoofing which isnt important to me). But this is not about the phone, but rather the audio features. I do not trust LG in regards to audio, but rather ESS. I really doubt LG had anything to do with the sound of the v20 Quad-DAC other than provide the necessary hooks in Android, and provide for the basic pin power lines needed to the chip. When the hi-fi DAC toggle is thrown, you are just listening to ESS, which happens to be implemented exclusively in the LG parts for now. My gut feel is that since the 9218 provides for custom filters (the v30 actually implements them via many choices), the B&O tweaking probably just implements more euphonic filtering choices. They are not modifying the IC. Also, prepackaging B&O headphones and sticking on emblems.

I'm sure this has been mentioned at some point in this huge thread, but anyone have any experience outputting directly to a headphone amp from the jack with any success? Is it worthwhile in anyway? From what I gather if you plug in an aux. cable it should default to some type of line-out setting, correct?

I don't really plan to use it with an amp, but it would be nice to know that if I did it would actually be an upgrade over just outputting from the jack.
Makes no sense using headphone out of V20 into an amp. Use the USB C out of V20 into a DAC/amp like Hugo, mojo, etc. and get great sound comparable to better DAPs.

Headphone out of the V20 into my various amps sound pretty good with the different audio apps that I'm using. All depends what mood I'm in when choosing a player app. Just like when choosing an amp, IEM or HP. I mostly roll with Neutron and REEQ at the same time with the V20.

Here we go, I have a pair of new headphones with low impedance (22), and they sound poorer than all I ever tried, there is no bass control, The cans are better with everything else but the v20
Why they did not think to put a power controller?

Got V20 without B&O logo. After a short session, it sounded very good (only tried low impedance). Some describe it as cold in the treble, I'd say it's even slightly harsh, but it doesn't damage the experience at all. I only noticed it with some mp3 songs, perhaps it's just very sensitive to compression (but I can only imagine that anything below 320kbps is not gonna play nicely).
Tried it with stock player and play music which sounded better, foobar also didn't damage the sound (I guess it uses the dac properly, could be wrong as I didn't directly compare).
Is there a final decision about which player does stuff the best? I don't want to experiment too much in these early stages, want to enjoy it the best way possible.

E: Spent some more time with V20. I love it. Surprised to learn about android problems with resampling, however, USB Audio Player Pro fixes this in a glorious way, up to the point where I can almost 100% guess whether dac is on using low impedance headphones. The thing is, Snapdragon dac is also a very powerful dac if implemented properly, and this is why it's very similar to quad dac when used with low impedance stuff. Too bad that it's mostly absolutely miss used with so many phones.
Looking forward to Android Oreo which has the potential to finally fix android's resampling garbage and then UAPP won't be a must.

Glad it worked for you :)







Glad it worked for you :)







The best solution is to go to android settings and change android sampling rate to "variable rate". This way you could play both Redbook and Hi-res files at their default sampling rate.
I just tested this and it clearly works (sampling rate is on the bottom of the track)


So I did confirm with adb that often files are played bitperfectly with the UAPP. But after sitting with it for a while testing many files I have found it is not true often enough :frowning2:

I was listening to Tidal, and I was hearing the high frequency noise/hash that really distracts from the fidelity. Also a complete lack of smoothness. It sounded like Tidal. Turning on adb I see the output is going through the mixer again. That explains it!!! 48K.. I shut app, exit it..flush OS....restart ......it starts playing again at 44.1!!! It sounds good again of course. VERY frustrating. I then decided to do many many tests on internal files... and network files. All of them play natively perhaps 50% of the time.... it is like a craps-shoot --- you never know what you are going to get. I then find that I can force it to fail everytime if any other app outputs or even initializes sound ...like youtube, other multimedia apps or android OS system sounds. Basically.......as long as the environment is multitasking.... the mIxer can get inserted in the path and whatever media player is playing will use 48Khz. I then talked to developer and UAPP is using audiotrack. So the behavior of the v20 with any music player using audiotrack will be indeterminate, like UAPP. I still think UAPP handles network files and playback better than any of the others I have tried (still excellent)....but it doesnt provide any magic around the android Mixer when calling AudioTrack APIs. I wish it did of course.

Some of this really makes sense in a broad way, as the LG V20 can sound so amazingly good sometimes...and sometimes hash, shrill and thin. A big part of this is just simply luck and if the android mixer is intercepting the sound, resampling ......or if it is handed DIRECT to the V20 ESS DAC.....which happens in a android environment when nothing else has played for a while and just the player starts with a native file resolution. I have seen 44.1, 88.2, 96, 192 Khz all play natively and sound fantastic though UAPP local and network based FLAC. Nothing sounds as bad as 44.1 played as 48khz though.

I hope somebody can fix this problem ...and stop having the LG V20 ESS9218 so hobbled and disabled by Android 7.

The best hope we can have is that in several months time Android O will fix all these resampling issues and we can just get back to musical bliss.

I have had my fair share of issues with UAPP too, namely, pops and variations in SQ when outputting to an external dac.

I've had a few hours to play around with mine now and I share the sentiment that while the sound is very good overall (def. audiophile grade) some songs can sound overly sterile and cold (vocals especially). I've tested all of the modes, although not extensively. Seems like that's just the nature of the ESS dac's being used which I haven't had much experience with prior to today. They somehow manage to make music sound sterile but engaging at the same time lol. I'm sure I'll get used to it though

I have been using v20 for a month now and as soon as i got my hands on it, i installed viper4android, Poweramp Alpha 703 build and Rootlinux's High Impedance mod and MAN OH MAN the quality and the output that this device throws is MARVELOUS ..... am using my FIIO F9 earphones with Balanced Cable and FIIO L26 2.5 to 3.5 mm converter cable ....

Holy crap!!! You nailed it!! I noticed this too but didn't understand What was going on. So is there a fic for tidal? Should I start the uapp first then play other files?

me too, but trying to fix the upscaling issue. Install uapp, you will notice a difference.

Why didn't the idiots at lg sort all this out? it really pisses me off. No blaming Android, because they can fix the settings with root access like we do. Lazy Basterds! They know people are using Tidal Hifi for flac!!!

When I play anything though Tidal....I have never seen anything but 48Khz streams sent through to the v20 by the OS. I have never been able to find a time when it played native 44.1 streams. At least with UAPP, 44.1 streams occur maybe half the time. So much better chance of better fidelity through UAPP. Not a fix, but something in the meantime. I have sent comments to Tidal about how to bypass Android mixer.. and improve fidelity --- no reply from them :frowning2:

I have root, will try to figure it out. I wonder which file will handle this? Can you post the Adb results you're seeing to determine whether apps are using android mixer or not?

The problem is likely in the flinger/mixer routines that are part of the libraries used for sound. The mixer does whatever it wants really..based on source sample rate...what else is going on ...and some complex decisions that likely factor in barometric pressure and ambient temperature (LoL). Upsampling and downsampling are not done well. bottom line -- lots of ripple and noise.

When played correctly and sounding right the adb ouput with the following command is as such:

adb shell dumpsys media.audio_flinger
