[LG V30 Questions & Answers] johnp357:
I don't understand how a regular adapter would cause the v30 to increase volume. The one Chazz is looking at has actual impedance resistance and that makes sense. But this one does not??
[LG V30 Questions & Answers] mlknez:
Just volume and increased noise.
[LG V30 Questions & Answers] Deadeye*:
Increased noise? really where did you get that info? i'm having impression because that noise should not increase.
[LG V30 Questions & Answers] RockStar2005:
Treo,

Ok. Let me know what you think of them. I tried them before and wasn't a fan, but a lot of ppl like them. They were comfortable, but I felt the soundstage was pretty small and they seemed a bit too bassy. But everyone's different so I guess just see what happens.
[LG V30 Questions & Answers] NotATreoFan:
The adapter trick causes the phone to activate External Device mode, which increases volume and power output. I was using a set of 80ohm headphones with the V30, but for some reason both the V20 and V30 don't always detect the headphones properly and trigger HIM.

You don't want to do this trick unless you have headphones that can handle the extra output.
[LG V30 Questions & Answers] johnp357:
that's the part I'm trying to understand. what in the adapter causes that?
[LG V30 Questions & Answers] NotATreoFan:
The extension part does it. It won't work if you plug it in with the headphones already connected on the other end.
[LG V30 Questions & Answers] psawjack:
The combo of an object being inserted into the headphone port combined with an open circuit because there is no connections in the adapter listed above.

The one that Chazz has linked actually causes impedience across the circuit and thus will trigger high impedience mode.

Edit:. Full disclosure - I may not know what I'm talking about...I'm not an engineer, just play one at work[emoji6]
[LG V30 Questions & Answers] psawjack:
I pulled the trigger on ordering one of the Danu 75 ohm adapters for use with my Aeons. I like them way too much to just stop using them due to the impedance thing with the DAC.

Hopefully it will work out. I'll keep everyone updated.
[LG V30 Questions & Answers] ra990:
Really wish that they'd made the impedance modes user selectable. I've got headphones that are low impedance but require a lot of power (planar magnetics) and it's a chore to have to use dongles and other things to trick the phone to doing what I want. I know the V20 had some patches (that required root) to always have the phone be in high impedance mode. Is there anything like that for the V30 yet?
[LG V30 Questions & Answers] Buckwheat6:
Hi all,

I have been following along with this awesome thread, patiently waiting for the unlocked V30 to be released next week. Upon reading about the adapter trick, I'm very surprised to see that not one person mentioned any fear of using one of these adapters that weren't of the L-shaped variety (as most headphones are these days.) I would never, EVER even THINK of using a straight line adapter into the headphone jack of a $800-$900 device for fear of yanking it the wrong way and permanently damaging the headphone jack. (I can't tell you how many Sony Walkmans I ruined in my youth LOL!) Just a thought.

Also, I can't even find any L-shaped adapters......
[LG V30 Questions & Answers] ChazzMatt:
Try Google. ;)

https://www.google.com/search?ei=mb...1.1.64.psy-ab..0.2.162...0i13k1.0.17MqJ-NUuB4
[LG V30 Questions & Answers] Buckwheat6:
Gee, Google? Yeah, never heard of it...

All I had meant was, since my knowledge of the technical aspects of what would work and what wouldn't are limited, I didn't want to suggest that those WOULD work (I DID Google before I posted FYI and even OWN one myself but wasn't sure.)

Google it. That's rich.
[LG V30 Questions & Answers] ChazzMatt:
Well, you were the one who said "Also, I can't even find any L-shaped adapters......" You would be surprised how many people do post a simple question without first checking Google. I was seriously trying to answer your question to show you plethora of L-shaped 3.5mm adapters out there.

Now, I can't find any impedance L-shaped adapters (even with Google), but that's not what you specified, as in this thread we are talking about two different adapters --

the "external" adapters, to just boost audio somewhat and

impedance adapters to trigger the minimum 50ohms HIM (High Impedance Mode).

However, you could piggy back these two to get L-shaped AND impedance. The L-shaped are like $1 each on eBay. The impedance are less than $10.

_________

to further clarify the conversation:

So, if you ONLY had the L-shaped extension, you would always first have to plug it into the phone and THEN plug the earphone jack into that -- in a 2-step process -- to trigger the higher volume "external adapter" mode. (You would still get the "yank" protection with L-shaped adapter even without higher volume, but only the higher volume if you plug in with that 2-step process.)

However, if you mate the L-shaped adapter to the impedance adapter and keep them both plugged onto the male end of your earphone jack, just by plugging that into your LG V30 that will ALWAYS trigger the high impedance mode, and still keep the "yanking" protection you want with the L-shaped adapter. No 2-step process needed.

Of course, you want earphones that can handle this.

If this is incorrect in any way, please feel free to jump in, anyone.
[LG V30 Questions & Answers] Buckwheat6:
Thank you, sir. That does clear things up. (Gotta love those detailed answers -- you are the MAN!)
[LG V30 Questions & Answers] NotATreoFan:
My 75ohm adapter came today. Will be testing shortly to compare it with the External Device trick.
[LG V30 Questions & Answers] bilbo60:
Mine came yesterday and I really like how they make my 1More Triple Drivers sound.
[LG V30 Questions & Answers] RockStar2005:
Sounds good Treo!
[LG V30 Questions & Answers] NotATreoFan:
So I did a very informal recording using my iPhone 7 Plus to capture the different volume levels of the V30. Here's what I did:

1 - ATH-M50x directly to the phone

2 - External device trick with M50x

3 - 75ohm adapter using same trick method

4 - 75ohm adapter connected to headphones, then plugged straight into the V30

You can definitely hear some differences in the volume output, all of which were done at 50, but it's not as drastic as I expected. That being said, if I turn off the HiFi DAC and then turn it back on, there's a HUGE boost in volume. So I know the adapter is working. But I don't know that it's working a ton better than the external device one.

I also tested the headphones on my PC, which detected them as having an Ohm rating below 51. After adding the adapter and plugging them back in, they're seen as high impedance and with an Ohm rating exceeding 110.
[LG V30 Questions & Answers] ChazzMatt:
My 75 Ω impedance connectors all came from Hong Kong today also! I ordered the

generic

as well as the one with the

"Dunu" brand name 75 ohm connector.

(brand name which I had never heard of).

Both work equally well technically with my

1MORE Triple Driver In-Ear Earphones

(Impedance: 32 Ω) to trigger the quad DAC high impedance mode.

But for "fit", the generic 75 Ω connector won't slide down firmly into the headset jack hole with my

Ringke case

-- not enough clearance. But the Dunu will slide in through the case and firmly connect.

Whereas, on my

Tudia case,

both connectors fit equally well. There's a little more clearance around the headset jack hole on Tudia case -- just enough -- for either connector to snap into place. Both cases are basically the same "carbon" design, but there are differences apparently! I ordered the Tudia because of the additional side grip pattern which is not on the Ringke. Still deciding which case I like better.

$6 vs $15.30

That would be the only reason you would want the "name brand" over the generic -- if you have a case with too tight space around the headset jack. The Danu has a more narrow base, while the generic has a squared bottom that is too big for some cases.

Still waiting for arrival of the no-impedance L-connector which would add "yank" protection...

I would piggy-back that with the 75 ohm connector.

With that added, then wouldn't matter about the "generic" 75 ohm connector not fitting right into the case hole. The L-connector looks like it has the same narrow base design as the Danu connector.
[LG V30 Questions & Answers] NotATreoFan:
Same here on the case. I'm actually using my phone without the case today. Something I NEVER do, but I want to use my 4 hour roundtrip commute to better evaluate the 75 ohm boost.

Now the question is whether I buy a different case, or get the Dunu adapter and use what I already have.
[LG V30 Questions & Answers] bilbo60:
I did get the L- connectors you originally referenced, and they have a narrow end which should make connecting easier with any case. I also got the 20 Ohm impedance adapter, but they wouldn't trigger the High -impedance mode even though my total impedance should be 52 Ohms.
[LG V30 Questions & Answers] ChazzMatt:
Well, the 75 Ω connector will do the trick. ;)

You (not you personally, I know you know better -- but anyone reading this later) just needs to make sure the earphones you pair it with can handle it. You probably don't want to pair a 75 Ω connector with something like

Dollar store earbuds

to trigger High Impedance Mode in the LG V30. :eek:
[LG V30 Questions & Answers] bilbo60:
Right. I got the 20 Ohm and 75 Ohm. I just thought the 20 would make it work with the 32 Ohm 1More = 52. My 50 Ohm headphones trigger high impedance mode.
[LG V30 Questions & Answers] ra990:
Isn't the idea with these adapters to trick the phone into high impedance mode and then remove the adapter before attaching your headphones? You'd need a short extension cable connected to the phone that you initially plug in with the adapter attached, then remove the adapter and plug your headphones into the extension cable, right? Are you guys just leaving the adapter plugged in and then connecting your headphones to it? That's not a good idea from what I understand - it may cause degradation of the audio and distortion in some cases.
[LG V30 Questions & Answers] bilbo60:
I've been leaving mine connected. If I do it the way you describe (which is the way I believe it worked on the V20) the display comes up as "an external audio device is connected. I can't get into "high impedance device". Once you disconnect the cable the settings close. I notice no distortion of the sound, in fact I think it sounds better.
[LG V30 Questions & Answers] johnp357:
any way to quantify the impact on the sound of the 1more after this test? I think the headset was really pathetic low end wise as is.
[LG V30 Questions & Answers] ChazzMatt:
Why would it cause degradation of audio and distortion? It's just adding impedance.

I'm leaving mine connected to trigger high impedance mode, which unleashes the full power of the quad DAC.

Also with the 75 ohm connector, you can leave that plugged into your headphones. Plug into the phone. It's not a 2-step process, like the "external connector" trick.

[LG V30 Questions & Answers] ra990:
The idea is to get the phone into high impedance mode, which like you said, unleashes the quad dac to it's full potential, then you take the impedance adapter out (leaving the extension cable plugged into the phone which leaves the phone in high impedance mode), and plug in your headphones. By adding impedance, you're restricting the amount of power going into your headphones, which was why did all this in the first place, right? To get the full power of the quad dac into your headphones....

https://en.wikipedia.org/wiki/Electrical_impedance
[LG V30 Questions & Answers] ChazzMatt:
You're confusing the two topics of high impedance mode and the external connector trick.

A no impedance external connector will boost audio levels.

A high impedance connector (or headphones with impedance built in) will trigger high impedance mode in the quad DAC.

What you are describing cannot be done -- removing high impedance connector and remaining in high impedance mode.

When you remove the impedance (whether connector attached to headphones or high impedance headphones), the high impedance mode automatically turns off in the Settings.

Sent from my carrier unlocked LG V30 US998
[LG V30 Questions & Answers] ra990:
Try this:

1) Plug your impedance adapter into a headphone extension cable's female end (nothing plugged into V30 at this point)

2) Plug the extension cable + high impedance adapter into your V30 (the V30 now goes into high impedance mode)

3) Remove the impedance adapter from the extension cable, but leave the extension cable plugged into phone (V30 stays in high impedance mode)

4) Plug your headphones into extension cable (V30 now sends full power, unaltered, into your headphones via extension cable)

You can leave the adapter plugged in if you want for convenience, but you're going to get more volume without it using the method above.

Also, please be careful and start out at a low volume when you do this. The V30 can output a lot of power that might destroy headphones that can't handle it!
[LG V30 Questions & Answers] ChazzMatt:
I don't have a no impedance external connector with me.

I do have one back at the house. But I'm at work now.

I had plenty of audio last night. I guess I don't see the need? It sounds great with the connector.

But I'll experiment tonight.

Sent from my carrier unlocked LG V30 US998
[LG V30 Questions & Answers] ra990:
That's what I'm trying to tell you. You need a short extension cable to achieve what you really want, which is the full power of the quad dac going to your headphones. If all you want is for the phone to display high impedance mode, then great, you can do that with just the impedance adapter, but you're adding impedance between the phone and the headphones with it plugged in...if you want full V30 power to the headphones, you can't leave that adapter plugged in. You just need to add something like this to your setup: http://a.co/e7oXwSs
[LG V30 Questions & Answers] ChazzMatt:
I remembered I do have one back at the house. I'll experiment tonight.

But, my earphones do sound good with the 75 ohm connector...

Sent from my carrier unlocked LG V30 US998
[LG V30 Questions & Answers] ra990:
Yea, I mean depending on the headphones you might be getting perfectly good sound and not really need anything else. I'm just talking technically what you need to do to send full power to your headphones. By no means is this necessary if you're happy with what you are doing.
[LG V30 Questions & Answers] NotATreoFan:
I know from my test last night, the audio is louder when using my headphones with the 75ohm adapter instead of the extender that tricks the phone into external device mode. And plugging in the ohm adapter without headphones, then plugging them in, results in lower sound levels.

I've been using the external trick for over 2 weeks.
[LG V30 Questions & Answers] ra990:
You have to use the extender cable with the adapter initially, then unplug the adapter. It's not either or. A lot of people are confused at how to accomplish this but go back a couple posts and I've listed the instructions step-by-step.

I blame LG for making this so complicated. They could have easily made this a setting on the phone that could be changed by the user, but instead we have to use a combination of an extension cable and the impedance adapter to "trick" the phone to output as much power as the DAC/AMP is capable of.
[LG V30 Questions & Answers] NotATreoFan:
I did see those steps, and will try it once I get home in a couple hours.

Just to be clear, you're saying that using the 75ohm adapter is increasing volume (which it is), but that it's also limiting power going to my headphones?
[LG V30 Questions & Answers] ra990:
Basically, yes. From my understanding, the impedance adapter is adding resistance to the power, so that's why the phone goes into high impedance mode and boosts its power output. Now you want to remove that resistance so you get the boosted power directly to your headphones. If you leave the adapter in there, then there's unnecessary resistance between the phone and your headphones; and although the volume might be louder than without the adapter, it won't be as loud as it can without that resistance in the middle.

Full disclosure - I'm not an electrician, but I did stay at a Holiday Inn Express last night.
[LG V30 Questions & Answers] NotATreoFan:
I appreciate the advice. And the Holiday Inn joke.
[LG V30 Questions & Answers] ra990:
It's just bad design on LG's part. They assume the only headphones that need a lot of power are going to be high impedance headphones. That's just not true. Sure, I have high impedance headphones like the Sennheiser HD650 that is 300ohms which works great with the phone without any tricks involved. But, I also have planar magnetic headphones that are very low impedance but require a lot of power to drive them, for those I have to resort to these tricks when I should just be able to toggle it in settings.
[LG V30 Questions & Answers] bilbo60:
Mine does not work this way. Followed your steps.

Step 2 does not go into hi impedance device but external audio device.
[LG V30 Questions & Answers] ra990:
You know what, you are probably correct. Thanks for trying. I could have sworn that's how it worked with the V20, but what you say also makes sense. The resistance might be added after the extension, so maybe the V30 isn't picking that up. I am still waiting for my impedance adapter to arrive, but that's how I understood it should be used. If someone else could try the way I suggested and report back, I would really appreciate it. I have the T-mobile variant, so determining what mode it's in is not very easy - so maybe someone with a Verizon variant can try.

I just switched my 550ML to a 551ML. The original Shakalaca root from two+ years ago works just fine on my old 550ML, but same procedure bricks the new 551ML.

Hi!

I recently got my Polaris, it is great! everything I ever wanted, but

....IT was PAINFULLY slow sometimes (a lot slower than S730, TyTN II and even the Touch Dual. ) (no this is not related to videodrivers, although they are needed as well!!)

So I spent some time figuring out why, and I found it!

The swedish rom is packed with stuff, like opera, and other things. Among this are the well known "Big start menu" and "Task manager"

Not sure which of these are the bad guy, but I disabled both and what do you know, the device is A LOT more responsive! (now it is a fast (well everything is relative) as a TyTN II and the other 400mhz devices)

Still need the videodrivers though for hardcore gaming and videoplaying (although coreplayer does a great job here!)
[Touch Cruise General] SvanteH:
How do you disable the Task manager? :)

[Touch Cruise General] princeliam:
You know what? I think you're right! Tested on a french "SFR/Vodafone" ROM.
[Touch Cruise General] cybertron:
You go to "Settings -> System -> Taskmanager"

Go to "Button", unckeck "Activate fastmenu on today screen" (or something similar since I am on a swedish rom)

again, not sure which of the two that makes your device slow as hell...but it sure does make a difference.
