Hi been playing around with the v20 for the past week. I realised that there is two modes on the dac feature.
1) High impedance device
2) Normal device
( I have attached pics)
Everytime i plug in my head phones, i can only enter normal device mode. There was 2 times i got v20 to recognise high impedance device mode. Once was when i reboot the phone, second was when i uninstall poweramp and reinstalled it. Anyone else have this problem?
There is very minamal difference between dac off and normal device mode. (Volume levels a bit higher). There is a huge difference between high impedance device mode and normal device mode.
I have the following headphones all which should be entering high impedance device mode.
1) UE 18PRO
2) JH LAYLA
3) JH ROXANNE
4) SHURE SE846
Any one know how to fix this?
There is also "An external audio device is connected" mode...which is in between Normal and High Impedance.
It seems that a headphone over 40 ohms will trigger the high impedance mode.
To trigger the "External" mode with a headphone less than 40 ohms...either use a headphone adapter or by plugging in the headphone chord to the V20's headphone jack before attaching it to the headphones.
I agree this is a big issue, IN FACT, the B&O play H3's for the promo have arrived and I can confirm this issue with those headphones too. Only one in maybe 10 tries does the phone actually recognize these as hifi headphones!? Lets get this ball rolling, either we need a software update or LG is gonna have to suck up some serious $$$ loss because i'm not letting it go.

All of your devices are low impedance devices. A high impedance device would be a Senn 800, Stax. that kind of thing

You are conflating three different things.
HiFi mode (turning on/off of the ES9218 DAC) does not equal louder (high gain mode)
HiFi mode does not mean that the ES9218 DAC is being used to its maximum capability (big problem!!!!)
HiFi mode is not turned on/off based upon the type of device plugged into the 3.5mm jack.
The B&O IEMs are decent. They are low impedance thus they should not engage high-gain mode, but like any device, they will engage the ES9218 DAC by default.
My Marshall mode is recognized as high impedance device. It seems only those 40ohms and above are recognized as high

I get High impedance mode with the B&O but it takes many tries. Not sure if this is an issue with the V20. The sound is a lot better when in High mode vs Normal with the quad dac on.
I was wondering why the B&O were triggering the High mode cause I looked at the specs and they're 18 ohm headphones
This is my B&O headphones, did a reboot and on the second unplug/plug I got high mode
The DAC on the v20 is a joke. The V10 worked much better. I'm glad I went back to my Note 7.

You're so funny! not.
You can go in the mixer path file on phone and make it recognize low ohm headphones as high. All you guys are doing is pumping more voltage and volume to a device that doesn't need it. Would you push 500 hundred watts of power to a little tiny bt speaker and put the volume on 1? You guys should do some dac research. You're missing the point. And headphones don't have to have a lot of resistance to be good, my shure se846-cl's are only 9 ohms and they do some serious work. I can't even make em clip or sound bad barely they just pump out high spl's.

LOLOL! Seriously? I am sure the V10 is a pretty good audio device but I have had the V10 before the V20 and IMHO, the V20 is a far superior DAP than the V10. I am also comparing this to my FIIO and Xduo DAPS and the V20 blows them away. This bad boy can handle anything you throw at it.

Just got the Hi Fi DAC and at ridiculously low price of £50/$66 to boot!
Sounds awesome and the module itself is using the flagship ES9028 SABRE DAC and 9602 Headphone Amp: http://www.esstech.com/index.php/en/news/newsroom/ess-technology-comes-out-play-lg-g5
even the upcoming V20 is supposed to have the next level DAC down (ES9018)? correct me if i am wrong!
The sound is MUCH louder than the built in sound via headphone and the sound stage is brighter and more balanced, even on standard resolution tracks with spotify (i have a free year sub on Microsoft Groove and it sounds great on there too).
love the fact that it can operate as an external DAC and quite literally has saved me so much money. I was going to purchase a 32bit/192 Hi Fi grade DAC from Cambridge Audio to Drive my Cambridge Audio Amp and speaker setup at home. HiFi Stero grade DACS tend to use a Sabre or Wolfson DAC. I've saved myself over £500!!
This sounds amazing when hooked onto a laptop.
Was at a party and people were connecting their phones (mostly iPhones) to an external speaker via the headphone jack. this module was MUCH louder than all the rest and drove the speakers better with clearer sound quality.
Only negatives i have found so far are that the module can sometimes be shaky which causes it turn off and resync on the odd occasion. It runs quite warm when used and it does drain battery noticeably more than if i just used the on board sound. I always carry a fully charged spare battery anyway so not that fussed.
Thought id just share my thoughts so far and open a thread where other users can comment on their experiences.

Anyone know how to fool the v20 into thinking it's in high impedance mode while listening to headphones?
? click the hifi dac button?
Sent from my LG V20 US996
you can try a splitter y cable. usually used for plugging two headphones into one port. You may need to try different brands.
I guess I'm confused. I thought the hifi dac button only had one option and didn't change based on higher impedance?
Sent from my LG V20 US996
Going into settings where you can turn it on and off, it will say external or high impedance ..depending on what you plugged in. I asked this before..and to quote someone else, you may be able to fool it by using splitters or extenders, but you may damage your head phones in the process
Just watching the htc u11 coverage and the noise cancelling type c headphones. Would it increase the experience on devices like the axon 7 when we've still got a headphone jack ?

shouldn't it be the same? I don't think there would be a difference besides the noise cancelling. Maybe those headphones get the power for that stuff from the USB but some noise cancelling 3.5mm with battery should be the same...?
Otherwise the only way I can think of to test if they're better or worse is by modding them so that the noise cancel is off, and test with USB-C then put them a 3.5 jack and test them too.
But you won't be able to charge, for what it's worth
Please correct me if I'm wrong, I probably am anyways
The audio wouldn't use the device's amp and dac and so the audio could be better on phones with really bad dacs and amps but on phones like the Axon 7 and LG v20 then the audio would most likely be worse.
You get an audio that is the same and more objective across devices because the headphones uses its own dac and amp, so the headphones can be better tuned by the manufacturer because your player no longer matter. Also, the power supply from type-c enables active noise cancelling without battery such as JBL reflect aware c, HTC usonic of U11, Xiaomi active noise cancelling earphones.
However, senny is probably correct as usb-c earphones may not use high end dac and amp.
Dac's are only connected to 3,5mm jack, stereo speakers and probably to microphone (to be confirmed) so there will be no Dolby features with type c headphones.
There one advantage - if you have active noice cancelation they can be powered via USB type c the same time you keep using it.

Dolby seems to work with BT speakers (tested this myself), so it might affect usb-c headphone. Mins toy it's just the equalizer that worked not the HiFi mode

With the excellent DAC/AMP and audio capabilities of the Axon 7, I don't really see the benefit of USB-C headphone. And as I'm nor sure if the USB-C headphones would bypass the built in DAC/AMP it may be worse, I don't know. Either way I don't really see an advantage. Of course you loose the ability to listen to music while charging.
If Audeze comes out with a USB-C version of their Cipher cable that has a built in DAC/AMP tuned for their specific headphones (EL-8, Sine, iSine), then that might actually be worth getting. But as of yet the Cipher cables is Apple Lightning port only and their headphone are expensive audiophile grade headphones.

Why? Usually the headphones that are included for free now aren't very good sounding.Who going to pay a fortune for headphones that sound as bad as the standard offerings?
If USB-C becomes they way things go for headphone audio, which remains to be seen, you'll have a range of choices of various price point. Only those that want truely steller audio will spend a "fortune", just as it is now.

Eh, I don't know. If you refering to a high quality DAC/AMP like whats in the Axon 7 maybe not cheap but not a fortune either. But most phones have a mediocre audio out put in comparison. I sometimes use headphones with an $15 external Mpow Bluetooth receiver that delivers more power then my other phones (Nexus 6P & LG G5). There's always the USB-C to 3.5mm adapter that the few phones that don't offer a headphone jack come with. Of course lets not forget most devices still bring a headphone jack, and hopefully it will stay that way for a while.
At any rate as far as the original question posed in this thread, a USB-C headphones will not really being anything to the table as far as the Axon 7 is concerned as it has one of the top headphone jacks currently available.
Until someone offers a very high quality USB-C pair of headphones that can outperform the A7's built in solution it's not needed. Even if and when something like that becomes available it only for you average user, but those who really really care about their audio and are willing to pay for every last bit of it.
I just don't see it costing a fortune, unless you want REALLY REALYY good audio, pretty much as is the case today.
So I just got my HTC U11 today and spent a few hours setting it up. I finally got around to trying out the phone's audio capabilities.
USonic - they sound good for out of the box earphones, but they're definitely not as good as my V-Moda Forza's. I could tell immediately. I doubt I'll use this.
DAC adapter - I'm conflicted. I'm still trying to decide whether or not the adapter sounds as good as my HTC 10. My initial impression is that it's not as good. The 10 has a cleaner, fuller soundstage. I'm really bummed about the BoomSound Dolby and tuning mode not being present on the U11. I've never really listened to the 10 without that mode on, so maybe that's the reason. The U11 doesn't sound bad though.
What do you guys think?

Pretty much this, most people will love it but I think anyone who had a HTC 10, an Axon 7, S7 Edge (Exynos, volume modded) will notice a bit of a step down. More so the AMP is weak rather than the DAC being bad (although Juan at PocketNow numbers show the DAC to be worse than the HTC 10, Axon 7, S7 Edge, iPhone 7).
I'm contemplating getting a Fiio K1
I just compared the sound quality between my 10 (without BoomSound on) and the U11, and they do sound quite similar.
This leads me to my disappointment -- why did they remove the BoomSound frequency tuning from the U11? It's nice that they have it for the USonic earphones, but why would you need to create multiple audio profiles for those earphones, if there's literally only one pair of earphones that can take advantage of that feature.
I'll have my thoughts later today using a dt770 as my comparison between the 10 and 11. They normally require more power than my HD600. I don't use high impedance/low sensitivity HPs with phones anyway but I figured I'd test.

Wondering this as well, you can't edit the audio profiles anyway so what is the point in having more than one profile
I've been happy about the audio quality so far. The problem I have is that we only get 1 of the DAC to 3.5mm adapter cables included. Now in order to use my music at home, in car, and at work I now have to carry the cable around with me. It is not ideal to have to carry around an adapter. Getting the included earphones is cool (sound okay) but would rather received a total of 4 adapter cables.
I went to order 4 more and found out that they are in pre-order status. I'll just have to wait until they come in. Once I have an adapter everywhere then I won't be so pissy about it. Really wish they would have kept the 3.5mm, then phone would be considered my best phone ever.

There really was no need to remove it, only to use a worse DAC/AMP in the adaptor.

Great audio output
The HTC U11 did splendidly in the first part of our audio test. When hooked to an active external amplifier it delivered very loud and perfectly accurate output.
When headphones come into play the volume remains nicely high and the only reading to take a hit is stereo crosstalk. It's a moderate amount of damage there and will all the other aspects of the performance remaining excellent, it's a great showing overall.

My own personal experience, I found my DT770 to sound great but was 2 notches of volume below the 10. The 10 at volume 13/15 was the U11 at 15/15. I definitely can hear the crosstalk difference GSM has measured. Heard that before I saw the measurements. Overall, I can definitely live with this. Just hope I don't put myself in situations where I need to charge and listen.
My first impressions are that I'm not particularly impressed by the Usonic earphones - but then I don't usually use the earbuds that come with a phone.
Given the reviews here, I was a bit surprised to find the sound from the U11 adapter sounds better on first hearing than I was getting from the HTC 10, but then I haven't yet done a proper A-B comparison - it could be I was playing it a bit louder, or 'new device' enthusiasm...
As I said it already the 3.5mm adapter lacks Boomsound and this make a big difference with HTC 10, HTC can implement it in the FW of the adapter but we need to let them know we want it.

Agreed. I can see the logic behind HTC's decision, and I actually don't disagree with it. They dropped the headphone jack but added noise cancellation and a decent pair of earphones. This targets that iPhone userbase that only uses the awful in-box white ear buds. It's definitely better value for the money for the average user.
Perhaps they needed to compromise on sound quality, but it still sounds pretty fantastic with the adapter. It may not sound as good as the 10 (honestly though it's pretty close), but I'm not mad about it.
Which Boomsound speaker mode do you guys prefer? Music it theater mode? I feel like music more is crisper while tester is a bit longer but muddier.

I use theatre mode all the time but yes it is muddier than music mode which sacrifices volume for better audio quality
About stereo crosstalk can you ''fix'' it with V4A?
Or there are no way to enhance stereo?

I usually use theatre mode. If I'm playing through the speakers, volume is more important to me.
On another note, I'm having this horrible issue with BT audio. When playing music in google play music through BT earphones (jaybird x2) or my home speaker (LG soundbar), occasionally there's a really loud, awful screeching noise!
Anyone else have this issue?
Otherwise, BT audio is noticeably improved over the 10!

Was listening with aptX in my car for a while today and I had no issues along with noticing no difference. Same volume level when connected to an Audioengine B1 that has a 2 volt output to my Audison bit-Ten. Wish I could do a quicker back and forth test with my 10 but I'd have to sync the Bluetooth over and over.
I have to admit that I'm a little bit worried about the sound quality on the u11. One of the things that I really enjoyed on the m8 m9 and the 10 was the Dolby audio enhancement. I have been using that in combination with power amp music player for years and you'd be surprised what kind of sound quality I get out of my Sennheiser HD 558's. I can hear the bass in music the way it is meant to be heard, almost felt, I don't hear that distorted bass sound that you tend to hear on lower end devices.
This may sound stupid to some people but if the sound quality is not at least the same as what I get on my 10 then I'm going to send the phone back. I just got done trying out a $300 pair of Bluetooth headphones with my 10 and I was not impressed, they were close in some areas but for $300 I want more than close. There is a cheaper pair that I have been thinking about trying with the 11 but I'm not sure that I'm going to want to invest all of this money just to be able to say I own the new flagship, and get half decent sound out of it with headphones, especially when for all intents and purposes I'm perfectly happy with my 10.
Right before the phone ended up shipping out to me I was debating on canceling my order because once the feeling of new shiny device wore off I started the question what about the new phone actually got me excited and to be perfectly honest the answer for me is really nothing. I think edge sense could be cool but the apparent lack of support from case manufacturers has me a bit scared as well. I have never owned an all glass phone before and I don't think you could pay me enough to use this phone without any full-body protection I understand that the camera is much better but honestly I don't see a problem with the one that I have. So this could be the first year that I actually hang on to my phone.
I just paired this phone with the Fiio K1 DAC. Much better audio experience. The HTC 10 apparently was better than the K1 by about 10% so the fact that the K1 sounds so good compared to the adapter is quite telling
Guys I need your valuable opinion about the audio dac on this for NORMAL earphones like RHA s500. does it feel lot different as of compared to other phones on normal earphones or do we need High impedance headphone ?
Am in dilemma of purchase decision
Am a music lover
Getting fed better audio should benefit most decent headphones. Of course the higher quality headphones will see the most benefit and take full advantage of the V20's audio capabilities. You don't need high impedance to take advantage of the quad DACs capabilities. It just delivers more "juice" to higher impedance headphones that require more power to drive. Some specific lower impedance headphones may do better if you could manually turn on the high output mode, my Audeze iSine 10s for example, but in general it will be fine for most earphone out there.
Just tested my Axon 7 (also a with a high quality DAC/AMP on board) vs My LG G5 (standard built in audio) with some cheap but pretty good sounding earphone ($10 to $15 KZ ZST ). I can sounds cleaner and voices are a little "sweeter". It more noticeable with my more expensive gear.
If you're into audio the V20 or Axon 7 are the phones to get, but there should be other reason to select a phone as well. Unless you really really desire superior audio, I wouldn't make my buying decision based solely on that.
I can hear a difference. It clearer sounding and vocals are a bit sweater. If you not big into audio it may be a bit subtle, at least at first.
