Thanks, but I do not have the ability to root mine. So the 75ohm adapter wont work?
[LG V30 Questions & Answers] ChazzMatt:
It should, but you confused me by asking about aux cord, which does not trigger HIM.

Guess I'll find out, just have read that it doesnt work for some others. Other than that, I'm guessing the root option is the only way to trigger HIM with an aux cord connected. Unless someone else here has had success with the adapter?

I have the triple driver 1Mores and love them...so much that I am watching the Quads for a price drop. I used them with a short ext cable to push the DAC a little into the external device mode. Great buds for the price.

Oh, also use them with Bose StayHear+ tips (2 pair for $10 shipped from Bose). I could not get a comfortable fit with the 10 tips 1More includes...but that is my problem, not with the 1More tip selection.

The 75 ohm adapter didnt work. I guess I'll try the extension cord and adapter. Not holding my breath
[LG V30 Questions & Answers] ChazzMatt:
The 75 ohm adapter ALWAYS triggers HIM (High Impedanc Mode). You're either not doing something right or you don't have a 75 ohm adapter.

Attach it to end of your headset cord and plug the headset cord (with 75 ohm adapter on the end) into your V30. You do NOT first plug it into the phone, like the external cord trick. You plug the headset cord + 75 ohm adapter into the phone, in one step.

Well shi....i ordered the 75 ohm adapter, it looks like the one others have used and from the same maker.

How can I tell if it is or not? Im on the v30 btw

I've tried plugging in the adapter, it says external device connected. I tried plugging in the aux cable into the adapter and then those into the phone, says the same thing.
[LG V30 Questions & Answers] ChazzMatt:
What happens when you plug the headset jack into the 75 ohm adapter FIRST?

Nowhere near the phone.

Headset connected to 75 ohm adapter.

Then plug the headphones with connector already attached into the phone? That's why I said in my other post.

[LG V30 Questions & Answers] Tadcooper:
I think the problem lies in the confusion. I am not using a headset, I forgot to remind you (my fault) that I'm trying to use it for home and car audio.
[LG V30 Questions & Answers] ChazzMatt:
hmmm..... OK, sorry. I answer so many questions I didn't remember your details. When I went back to my post from days ago it just seemed to be a normal headset question.

What is the type of cable are yor connecting to the adapter on the other side, if not headphones then? Some sort of car stereo cable? I guess the point is, still try to connect whatever cable + adapter in one move. Don't put the adapter into the phone first. After that, I have no other ideas.
[LG V30 Questions & Answers] Tadcooper:
Ok, thanks. I use a standard auxiliary cable. I plug the aux cable into the adapter, then both together into the phone. I even tried having the aux connected to the preamp, then plugged the aux into the adapter then both into the phone. Still no luck.

I'll try the extension cord trick but i doubt it will work.
[LG V30 Questions & Answers] bilbo60:
What carrier are you on?

If you read back in this thread you'll see I could never get that to work.
[LG V30 Questions & Answers] dacksmax:
Verizon, why would that matter though? And you mean the extension cord with adapter trick?
[LG V30 Questions & Answers] bilbo60:
I'm on Verizon also. It seems to work a little differently, not sure why, but those who got it to work aren't on Verizon.
[LG V30 Questions & Answers] dacksmax:
Do you have a link to the post where they got it to work with the aux cord?
[LG V30 Questions & Answers] psawjack:
Any particular reason why you want HIM if you are connecting to an AUX in wither car or home? Are you having low gain issues?
[LG V30 Questions & Answers] dacksmax:
Because thats why I bought the phone. I wasmt aware it was only avaliable for headphones. And I wpuld likr to compare HIM off and on.
[LG V30 Questions & Answers] psawjack:
Quality of audio should be the same, HIM for higher gain with high impedance HPs.

In this thread try posts# 167, 178, 213, 218, 243, 244, 245.

You do realize your still using the DAC with just an auxiliary cable?
[LG V30 Questions & Answers] Tadcooper:
Ok, thanks. I'm gathering that is just won't work without a root hack.
[LG V30 Questions & Answers] Dans07SGT:
Just to maybe clear things up a bit when you are using the adapter. The male end of the adapter *has* to point towards the phone to trigger HIM. If your cable doesn't have a female end, you can't plug in the adapter to trigger HIM then remove it to enjoy the boosted performance.

Source: The aux cable for my car and one of my headphones uses a male to male cable and it doesn't work with them. ;)
[LG V30 Questions & Answers] demonknight:
Long term v20 guy using the phone as the audio unit on the car as well :)

What you need to do is to get an aux extension cable first. Plug in the impedance adapter into the extension cable and then plug in the extension cable with the impedance adapter inserted. Phone will trigger high impedance mode.

Now remove the impedance adapter and plug in your car's aux cable into the extension cable which is still inserted in your phone.

Voila HIM on.

Word of advice. It's not really worth it as you get the full effect of the DAC otherwise itself.

I just bought some soundmagic e50c 50ohm headphones to see if it made a difference over the ones that came in the box

Wow ... mind blown ... life changing ... no joke ... I listen to music all day at work as I am a postman ... the 50ohm headphones just bought this phone alive

LG should really provide high impedance headsets in the box , the difference is night and day between the included earbuds

It might be one of the best 50 pounds I’ve ever spent , if anyone is looking for a set of in ear headphones that trigger the amp at 50ohms I highly recommend these little bad boys
[LG V30 Questions & Answers] dacksmax:
Sorry for late reply, just git the aux extension. What you said didnt work for me, im on the v30. Fyi I have 75 ohm adapter

[LG V30 Questions & Answers] buxz777:
Hi mate sorry for the delayed reply .....

I get through a lot of headphones , I usually tend to go for something bass heavy with 12mm drivers or the new dual driver types but all my headphones are around 16ohm , they still sound great with the inbuilt dac but I wanted to hear the amp and have headroom to go louder if I wanted/needed .

For example I’ve been a lover of Sony in ears , kz in ear and over ear , sennhesier cx300s , bose and the most I’ve spent is about 120 pounds .... I don’t like to spend to much because I’ll often fall asleep wearing them , wear them at work carrying Mail bags across the wires , they are basically abused so jo pint in spending 100s on something that gets used like that , however I do want the best bang for my buck and I do like high quality music which is why I bought the v30

I mainly listen to drum and bass , hip hop , jazz , reggae so I do like my bass but I don’t like my music muddy

The soundmagics are quality headphones , they aren’t bass heavy but they aren’t lacking in bass either . They are very clear with tight thumping bass , I guess how the artists intended the bass rather than exaggerating it like some headphones do . They are advertised as studio type headphones so I guess they are a quite flat sound signature with slight bumps at each end of the spectrum

I am really enjoying listening to them on the v30 , I use them at about 60-65 on the volume of the v30 and they are very loud , very clear , the bass hits , the highs sing , I really really like them and obviously the v30 plays a big part in that with the dac and amp to power them well , some reviews say they are lacking but I presume they are using them on standard phones that would have trouble with the 50ohm

The wire is top quality , the ear buds are small and light but built well , the controls work fine on the v30 and my friends said the mic is perfect

When you switch the dac on and off in the settings the difference is night and day , they come alive , seriously LG should have put these in the box with the phone to show how much difference it makes

Buy them from amazon , find the right tips , plug them into your ears so you get a good seal and play your favourite high quality music file .... i don’t think you’ll send them back mate lol ... if you don’t like them amazon will definitely take them back and refund you , it’s got to be worth a go

I was tempted by the e80c but they are 80 pounds and the way I use the headphones it’s at the top,of the budget , I can nearly buy 2 pairs of the e50c for the price of one e80c and to be honest the e50c and this phone is the best portable set up I’ve had in a long long time , I also figured the e50c would be better to use on other devices to the lower impedance rating compared to the e80c

[LG V30 Questions & Answers] buxz777:
Hi mate they are 32ohm headphones , so they won’t trigger the high impedance mode or the amplifier , I am sure they will still sound great with the LG v30 dac though ✌️
[LG V30 Questions & Answers] dacksmax:

[LG V30 Questions & Answers] NotATreoFan:
75ohm - the one linked before that does not fit with cases.
[LG V30 Questions & Answers] Tadcooper:
I have that one too. Do you use that for headphones or auxiliary cord attachment? Ie, to hook up to car audio. If so, did you use the trick stated earlier? I couldnt get it to work. LG V30.
[LG V30 Questions & Answers] NotATreoFan:
Headphones. I use Android Auto over BT when in the car.
[LG V30 Questions & Answers] demonknight:
Could you please list out the steps you did? :)
[LG V30 Questions & Answers] dacksmax:
Exactly what you stated in your post. Used the extension cord above, plugged the adapter into that, then the extension cord, with adapter connected into the phone.

It just shows "an external device is connected". This is on the v30.
[LG V30 Questions & Answers] bilbo60:
Which carrier are you with?
[LG V30 Questions & Answers] dacksmax:
Verizon. The carrier model would be the issue?
[LG V30 Questions & Answers] bilbo60:

[LG V30 Questions & Answers] dacksmax:
Meh, I should just sell this one and get the unlocked US998
[LG V30 Questions & Answers] demonknight:
1) Connect male end of Impedance adapter into the aux extension cable female end

2) Connect male end of aux extension cable into phone

3) Phone should now show HIM

4) Remove only the impedance adapter leaving the aux extension cable plugged in. [Phone should remain in HIM]

5) Now connect the aux cable into the extension cable.

Was that how you did it?
[LG V30 Questions & Answers] bilbo60:
That's how I did it.
[LG V30 Questions & Answers] dacksmax:
Yup, it may be a verizon vs996 issue.
[LG V30 Questions & Answers] NotATreoFan:
I don't know what changed on my H932, but this no longer works for me. Plug in the cable + adapter, get HIM. Unplug the adapter, phone detects it was removed and reverts to AUX mode.

I'm not going to worry anymore, jumping back to the Note8 tonight. Too many software glitches and deleted messages for me to keep fighting the V30.
[LG V30 Questions & Answers] demonknight:
Ah ok. So LG fixed that loophole? Thou shalt not use HIM with thy Low Impedance Device! Thou had, not anymore.
[LG V30 Questions & Answers] ChazzMatt:
Unless you have bootloader unlock and root. We have two stock-based ROMs now with either

HIM enabled all the time

(H930/H930G) or

the option to do that (US998)

-- as well as a

standalone mod for rooted devices

if you don't want to install a tweaked, debloated stock-based ROM. (The ROMs incorporate that mod by [MENTION=4652765]Whiskeyomega[/MENTION].)
[LG V30 Questions & Answers] Rawcode:
What is the purpose to use High impedance as default setting on a non (enough) high impedance headphone?
[LG V30 Questions & Answers] ChazzMatt:
Many have said it provides a bigger sound stage. However, you would only want to use the minimal ohms to trigger that mode, as excessive ohms makes other sound profile changes too that your headphones can't handle well. In defense of LG, they claim the quad DAC will adapt to the earphones plugged in, but still this HIM seems to provide BETTER sound. The best case scenario would be like premium Triple Driver 32 ohms headphones which don't quite trigger HIM on their own -- but can with a little help from an adapter.

Down in the dev section there's a mod for rooted phones that turns that feature on ALL the time so you don't need 50+ ohms to trigger it.

Also, at least two of the custom ROMs we have for the H930/H930G and US998 incorporate that mod to always have HIM on.
[LG V30 Questions & Answers] sagor1:
Will it decreases battery?

I also wanted to use it for sound stage.

My earphone ohm is also lower.

Btw i am using lg g6.
[LG V30 Questions & Answers] Wolfsbane58:
This has been a topic of much conversation at some hi fidelity/headphone/music sites. Some of them have asked LG for some feedback on this, and apparently the perception of that increase volume/airiness/presence when you force the high impedance mode on non high impedance iem/headphones will vary depending on the type and construction of the headphones and its component transducers. Generally, (and the LG engineers have been notified by these users that there is an apparent issue with planar headphones), when you force a high impedance mode with non high impedance iem/headphones, you are forcing power to individual transducers at a different rate than originally designed. This is more so with hybrid transducer configuration systems. The result is that you get some bloat/unevenness at certain frequencies. Planar headphone issue is a bit different as they are supposed to be high efficiency and give the V30 some issues automatically detecting and providing proper power. But anything else, the LG engineers do not recommend defeating the intended engineered feature of the V30 amp. And yes, battery life will be affected when you power headphones with a higher impedance requirement.

The other thing I found interesting is the Quad DAC discussion. I was previously under the impression, based on what I read on several forums, that each pipeline comes on depending on power requirements of the iem/headphones. But the LG representative seem to indicate that the Quad DAC is activated based on a connection to a device through the 3.5 jack... nothing else. The amp section seems to be separate. Which of the Quad DAC pipe lines are actually active is based on source content requirements, but all four pipelines are active and available when the Sabre ES9218P DAC comes on.
[LG V30 Questions & Answers] daniel4653:
Is it necessary to use a 50+ Ohm earphones /headphones to get the most out of the HiFi dac? I have a pair of Xiaomi earphones that are rated at 32 ohms
[LG V30 Questions & Answers] Wolfsbane58:
The higher impedance affects the amp section. The Hi Fi Quad DAC itself does what any DAC does... take a digital signal, convert it into an analog signal that speakers can use, then send it to the amp section before it goes to the speakers. This DAC is a higher quality DAC than what you find in most other cell phones, though. You do not need a high impedance headset, unless your personal taste and preference calls for one with high impedance. Quite a few pairs of iem and cans that are below 50 ohm on various sites that are recommended.

The V30 just happens to have an amp section right now that few, if any mobile phone, can rival that can drive high impedance headphones. But base your decision on a pair of cans or iem, on a sound profile that appeals to you, regardless of its impedance. That’s the advantage that the amp on this phone gives you. And... yes. There are owners out there that are dropping a grand or two on a pair of cans. Quite a few open types. Love my music... but that’s way too much money for me.
[LG V30 Questions & Answers] starrynighthn:
Ok, so I have 2 times got HIM with NO adapter, just the phone and the LG B&O model come in the box. The sound is louder, not sure about wider range. My phone is Korean V30+ running Oreo, no root. The first time is on Nougat, if I remembered. Anyone experience this? Don't remember how I did.
[LG V30 Questions & Answers] ChazzMatt:
Here's why it's strange because you don't explain. ;) I had to do research. The B&O headphones tested by independent lab are 32 ohms. That's the missing context. How is he getting HIM with 32 ohm headphones?

https://www.0db.co.kr/xe/index.php?mid=REVIEW_0DB&ckattempt=2&document_srl=131333

Use Google Translate, and page search for "ohms".

I actually thought the B&O branded headphones were at least 50 ohms, but turns out they're not.
[LG V30 Questions & Answers] starrynighthn:
Thanks for the info. Maybe it just a bug of V30. Because the next time I plug the headphone in, it's back to normal mode. I remember someone posted the trick to get this without adapter somewhere in this V30 forum, but I cant find.
[LG V30 Questions & Answers] Valinorian:
Shame my klipsch x11 (50 ohms) doesnt get recognised as HIM.

Anyways I was so happy finding another pair of klipsch x11 for cheap after my old ones broke a year ago, loved the sound on my iphone with it..... thought with the quaddac in the lg v30it would totally blow me away.

Guess not, I love the sound signature from my klipsch headphones better with my iphone :(

[LG V30 Questions & Answers] Sony92:
Can anybody help me further? I also feel that when I use my inears, and I turn on the DAC, what's lost in sound. I mostly hear about the streaming app Tidal. When I did the dac and used the normal equalizer of Lg and it was normal, the sound did not sound like it was being output by Tidal. I then deleted the Equalizer App with the root Explorer and I already had the unadulterated sound, as it is intended by Viper. so I would like to switch the dac now, so that this amplifies the sound even more. but without the profiles of the dac. because they distort the sound again. that is really a shame.
[LG V30 Questions & Answers] BROKEN1981:
It's distorting due to the fact V4A can't work with the quad dac.

V4A will down sample while Android will up sample. V4A is processing the sound bypassing the quad dac

If you want to use the quad dac, let's be honest, that's the entire reason you bought the device, don't use that trash mod.
[LG V30 Questions & Answers] iRS_:
the quality was the same, just the volume was much higher in high impedance mode.

you can trigger it by using an impedance dongle or by editing mixer_paths_tavil.xml like in the attached picture
[LG V30 Questions & Answers] Sony92:
you'll be right. I only tried viper, because I wanted to raise a bit more clarity. Are there any good alternatives?
