For those of you with the quad dac, there is an interesting property I found out about how you can force the high impedance mode.
I discovered this trick on an Arctis 5 gaming headset by accident, but I found that it works with any device that has a physical volume control knob on it. Any device that let's you control the volume on a hardware level will work with this. So I guess I never really thought about how those devices work to lower the volume and now I know. They do it by increasing the resistance of the headphone as you turn the volume down. By increasing the resistance, they decrease the overall volume on a hardware level. By lowering the volume on the hardware side and upping the resistance you can trick the LG G6 into thinking you have plugged in a high impedance set. Now if you just raise the hardware volume the G6 will remain in high impedance mode. Interestingly, if you lower the hardware volume all the way, it thinks you have plugged in a line input. I am assuming something like this would work too.

how can i use this info to put my m50x into high impedance mode? right now, i just unplug the aux from the headphone and put it into external device mode before plugging the part that connects to the headphone back in

I've noticed that when I connect the phone to my car through the 3.5mm jack, the volume output is considerably lower than other phones or media players I have. Any fix for it?
I've studied the big thread about Volume Boost of headphones...
Is there anything around about non-headphones volume boost. My V10 is not very loud compared to my Note 4 with Viper ...
Thanks!
I haven't looked into the physical components, really, but if the dedicated ESS DAC with the amp act as any other dedicated components I'm familiar with, then you would have to physically change the wiring route to the speakers. Right now it's headphone only because the amp is directly connected to the output jack. The first issue is software-based, but the second (with the speakers) relates to hardware.
Again, I haven't really checked, so someone correct me if I'm wrong.
Is there a way to increase the maximum headphones volume ?
Yes buy another headphone i am already on samsung one and soud is awesome
i use Denon AH-C50MA and sound is great
What's you headphones impedance? Mine piston 2's are loud even 3 volume bars @ 16ohm
Well i don't care about my earphones impedance as my previous smartphone (S3) could easily drive these with louder sound.
I think i will probably give a try with Viper4Android.
I also find the Honor 7 volume levels too low. The phone speaker as well as the headset.
Call volume is low as well but you can fix that by setting it into speaker mode.
The low headset volume annoys me the most. (I use HQ headset)
I found the service mode menu and had hoped i could increase headset volume levels there.

Sadly, there is no option. I tried some apps from the playstore but they didnt do anything.
I'm currently (officially) participating in the Android 6 Beta so am not rooted or anything.
Is there a way i can increase the level already?
Or maybe once I have the final Android 6, can i root/unlock the phone and increase the volume in another manner? I want to stay on the original roms, dont want to flash something else on my phone.
Anyone else finding this annoying as well and has a fix?
I am running 80ohm sennheiser dt880 and the volume is high enough for me so every mobile headphone with 32ohm should be easily powered to painful volume . Not sure which media you play, but if you need higher volume i suggest a mobile dac as headphone amplifier
On the V10 in order to have the DAC in permanent high impedance mode you simply modified the Mixer-Path.xml. I look for that file in the V20 system dump and couldn't find it. I was wondering if one or some of the great minds here at xda could search the system dump to locate the V20 Mixer-Path.xml or find a file that if modified would provide the same results when we get root. Thanks on advanced.

i don't seem to have an issue with high impedance headphones, i have a pair of Sony xba-h1 that have a ridiculous (for earbuds) 40 ohm impedance and they work wonderfuly. is there a reason you're trying to force it into high impedance mode?

Yes I want to use the full power of the amp on my low impedance rha ma750. I don't have to crank the volume as high and the sound is richer and crisper. [emoji2]

Would it be safe to use the high impedance mode for headphones which are not high impedance? My Bose headphones trigger the mode naturally but I wonder for my other headphones.

Until you find a software workaround, plug a splitter into the phone first. Then plug your device of choice into the other end of the splitter. This tricks the DAC into going into high-impedance mode.

Lot of factors go in to that. The risk is up to the people who try it.

That is aux mode not high impedance mode. You have normal (low) impedance, then aux mode (mid) impedance then high impedance ( max power). I'm shooting for maximum power. [emoji2]

Bump for this. Id love to see a high impedence mod. If someone could point me in the general direction to start looking on how to create some sort of mod, id love to try and see if i could mess around with it. Not sure how similar LG Nougat vs Samsung Marshmallow is...
There's a good amount of risk in doing that. You're forcing higher voltages normally reserved for drivers with higher resistance. Lower the driver resistance and your current draw on the opamps can hurt the device or fry your low impedance drivers if the gauge wire to the drivers isn't large enough. I don't really see the point in this mod. Any quality DAC is going to be able to drive low impedance hard enough. If your buds aren't loud enough, get better headphones. Just my. $0.02
I force mine into high impedance mode by using an inline sliding volume control, set to minimum when I plug in. It puts 470 ohms in series with my inefficient headphones. Slide it back to full volume after plugging in and I have 1.8V rms high impedance mode.
I too would like a software fix for this.

Not really. I got it in a shop in Hong Kong. If it is an analogue knob or slider then it could work.

I'm pretty damn sure that if LG believed driving the amp at 100% power, even for low impedance headphones, were a good thing, they would have done it.
My SE846 IEMs use the low power mode. They sound fantastic. You are not doing yourself any benefit by trying to trick the amp into a high power mode, especially by using some piece of crap adapter. If anything, that is going to degrade quality.

Yes, but your SE846 are sensitive. Other headphones may not be. My Sine headphones need nearly x10 the voltage to reach the same volume. Portable headphone with this low sensitively and low impedance are rare, so LG did not cater for it. But they did allow for it with high impedance headphones, which are typically less sensitive.

The high impedance mode says it activates at 50 ohms and above. Unless your headphones are above 50 ohms, and somehow not activating it, you're wasting your time.

I'm really not. They are 24 ohms and I get the power I need in high impedance mode.
I thought they were 18 ohms?

What is the mod please? I want to add it to my ROM
It's easy to force high impedance mode.
I've got a set of headphones with a detachable 1/8" jack at both ends, but you can use a splitter and an extra 1/8" double male plug cable as well.
I use the 1/8" cable and connect my v20 to another cell phone or tablet headphone jack. It immediately goes into high impedance. I unplug only the end going into the other phone and plug that end into my headphones. As long as the cable stays plugged into the v20 it stays in high impedance mode
If your headphones don't have a detachable cable, it'll still work with a splitter and a cable that has male 1/8" plugs at both ends.
Using the splitter, plug your splitter into the v20. Use the double 1/8" jack cable to connect the splitter to a phone or tablet. Once it's in high impedance mode, unplug the cable from both ends and connect your headphones to the splitter. Don't remove the splitter plug from the v20. As long as the splitter stays plugged, you'll be in high impedance mode and get more power into your headphones
Ok...what is the use of high impedance?

its just wasted a time, and change nothing on everything you hear. look, high impedance automatically triggered only if you put headphone with 50 ohm above. you know why? because regular phone or music player only could deliver impedance with range 15-30ohm. while lg v20 like any other DAP with external amplifier could support from 50-600 ohm. even with 250 ohm headphone if you put on regular phone it would only run on 30 ohm max. and same goes to your phone, even with your v20 or any DAP player which support 50ohm impedance above, if you connect to low impedance headphone it would only run on your max headphone impendance. its not something you could force to work.

Bro I agree with you. I have used 60ohms headphones and 45ohms headphones with my Lg V20. With 50hms and above, we can see "high impedance headphones connected" in settings.but nothing improved in sound quality. So doing force high impedance is unnecessary.

check your audio files first, make sure you have lossless audio like flac or dsd. for flac i recomended using song with 24bit/96khz. if you playing with stock lg music player you'll see there is "hifi" icon on the selected song. join audiophile comunity for more reference. and for headphones , well.. there are many type, some headphone have flat bass, more vocal, etc. choose one which suits you and the music you played. from what i got while browsing on auido/video community, there are 3 main requirements for best audio experience:
1. good drivers aka player like DAP/AMP or our beloved LGv20 which support impedance above 50 ohm
2. lossless audio files like flac, dsd/dsf which support hifi system
3. good headphone with high impedance that has many feature depends on your need. some people love high bass, while other prefer clear vocals, etc
lg v20 is a good drivers, its not the best but its good if you dont wanna spend another 150-250$ on music player with dedicated amplifiers.
High Impedance Workaround
I was thinking the same thing on an easy workaround, so I bought a $3 splitter, plugged in my AKG headphones which pulls up high impedance, then plugged the B&O earbuds. (that came with my V20)Then unplugged the AKG's and it remained in high impedance mode. Doing that, if you turn the volume up higher than 75%, you'll probably pop an ear drum. It gets waaay loud and clean!

Why not just use my mod and forget about extra cables?
NVM.. Just read no root. Sorry folks.

I never said it improved quality. I understand how DACs and amps work.
The reason for high impedance mode.... If you have headphones with less than the 50ohm threshold, high impedance mode increases power output from the amp. The result.... On low impedance headphones you get more power which means higher volume output.
I have a set of V-moda Crossfade LP cans that are less than 50ohm. On the regular power level, max volume of 75 still lacks a couple decibels for my preference. When I trip high impedance mode I am able to reach a higher volume level and I usually don't need to go higher than 60.

Exactly... Higher volume output. I didn't say it improved quality, as others are arguing.

Look at my last post.....
Triggering high impedance mode and then connecting low impedance headphones will give you more amp power which equals higher volumes. Does nothing about increasing quality just higher volume threshold. But only if you trigger high impedance and THEN connect LOW impedance headphones
This mod worked with a splitter in my v20. Thanks @Sid 6.7. wow listening to low impedance headphones at high power is a fun. Great workaround.
