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.
1. Micro-SD card slots - Is it UHS-1 (100mbps)or UHS-2(150mbps)?
2. Quick Charge/Adaptive Fast Charging - Looks like it's still QC- 2.0 since stock charger is having same rating as the one in S6 edge or 3.0 (so far only 6 phones are supported) or 4.0 (announced by qualcomm officially today) ?
3. Have any one tried type-c headphones - any improvements over 3.5mm if it works.
4. There are rumors that Camera sensor uses Sony IMX333 capable of 1000fps.
4. As far as I know the only Sony sensor capable of 1000FPS is IMX400 and it's 19MP. It has extra memory build inside sensor and ours doesn't, so no.
3. I'm not sure what kind of improvement can one expect from headphones connected to USB C, so please enlighten me, just don't quote some BS Apple's advert.

3.5 mm headphones can introduce noise which usb type c would not. Also if the headphones have a built in dac better then the one in the phone they could easily sound better. I personally enjoy the tuned by akgs but made by Samsungs though.

maybe if you had cheap headphones plugged into a cheap computer on a cheap old circuit in an old house or something
plugging it into the phone, 99% of the time there will be no noise

I only said it was possible. Haven't had that issue but again if the headphones had a built in dac that would make a difference.

I am not sure, but I thought I readed that there was a DAC, which was even improved so it could process 32bit audio? Don't pin me on this, but from what I can say, the music sounds in comparison of my old S6:
1: Way better, clearer.
2: More loudness.

The only way I can think of the noise being introduced on 3.5mm jack is induction on the analog wire connection which should be fixed with shielded wire. Now, are you trying to compare some cheap analog headphones that don't even have shielded wire, with digital headphones with build in expensive DAC?

Okay but even if it has a built in dac it could be better. I never had usb headphones at all. I don't plan on buying any either because I like to be able to keep the usb port open. I doubt there is any reason I would actually come up with that would make it seem like a worthwile purchase for me.
USB headphones are possible with the Galaxy S8. I have used my fairly inexpensive PC USB headset with the Galaxy S8 using the included USB C to USB A adapter, and it works flawlessly. The only use I have found for this is that I can leave the headset plugged into the port on the bottom of the GearVR that way once the phone is in the headset it's simultaneously connected to the headphones and without the lag that Bluetooth headphones may introduce.
On 4 - they use imx400 only in Korean version with 6gb ram, but the 960fps(not 1000) is not avaible for Samsung, its Sony's trick
About QC, i have s6 edge and my roommate have s7 edge, the s8 is charging faster even with bigger battery, idk if its 3.0 or 4.0 or whatever, but its faster than the s6 and s7
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.
I will be receiving my LG G6 asia version next week. In order to take advantage of the Quad DAC, may I know earphones or head phones I should get ??
I had similar problem. I've started \ found those threads. Maybe it will help you.

Just forget all that DAC nonsense. Its still not clear if the High Impedance mode just makes the phone louder or triggers all DAC Channels. And its not sure how the DAC works. But one thing, i dislike the Quad DAC, it doesn't sound atmospheric and nice to me. Its very analytic and boring for normal people. If you plug in Earphones with "normal" bass, you will be dissapointed completely, the DAC cancels out every bit of Deep bass. I bought a USB DAC (Zorloo Zuperdac) and i prefer it a thousand times to the Quad DAC. And its also louder.

Has anyone tried to compare the audio quality of OP6 via headphones jack with that of OP6T via the dongle? Just trying to find out if OnePlus uses another DAC chip in Type C port or the one in SD845.

The Type C dongle is passive the DAC is in the phone and not the dongle whihch is dissapointing and the quality is around the same as OP6 better off trying to source a 1st gen Google dongle or find a brand that makes a good one.

Exactly. The audio quality out of the dongle is so disappointing. It makes my FiiO F9 Pro soundstage sound narrower that it's supposed to. That's why I'm currently deciding whether if I should buy a FiiO Q1 MK II. But I never tried any of these amps before, I don't know if there would be a substantial improvement over the dongle

If there is a DAC in the phone, does plugging in a cable like this (which as a DAC built-in) tell the phone to send a non-processed signal straight out to the cable (so that the cable can do the d/a conversion)???

Is there a way to confirm which DAC it's using? I'm not doubting it's passing audio from phone to your headphones but is the D/A conversion still being done on the phone and sending an analog signal thru your active cord OR it the cord actively doing the D/A conversion? Is there a way to tell?

I read it in a Reddit thread where it was mentioned that if you're using a dongle with a built-in DAC, it will use the DAC in the dongle instead of the one in the phone. I'd assume it's the same for other DAC as well. https://www.reddit.com/r/oneplus/comments/9uu3jy/oneplus_6t_has_an_analog_dac_inside_the_usbc_port/
Edit: After testing for many times (I hope the port life won't reduce after those tests), I can conclude that the phone is using the external DAC. Noticeable difference in the soundstage
Then theoretically op6t with fiio k1 should work, right? I have a pair of Sennheiser HD 598
I don't use any external DAC. I stream in the car, and I use V4A for audio processing, and it sounds incredible.
Get yourself one of these https://www.nexum-design.com/aqua - couldn't recommend them enough. I have one and it is absolutely the best 'dongle' you can get. Battery does take a hit because of the integrated amp, but well worth it...
