    Yes, there already exist adapters to go from TRS to TRRS, but they connect the "RS" of the TRRS plug to the "S" of the TRS jack, and if the issue involves contacts of the TRRS jack of the phone losing contact with the "S" of the TRS or the "RS" of the TRRS plug, then the same issue will continue. If you were to make sure that either the second "R" or the "S" of the TRRS plug is NOT connected to the "S" of the TRS jack, then that would prevent the issue. My only fear is that the phone checks whether there is a TRS or TRRS plug inserted, and if it does, then this might confuse the phone.

    I have the same issue with my hd 700's. Every time I plug my headphones in I get that google prompt. My guess is the Jack is touching something inside the phone is causing this. This is my second v10 as my first one the headphone jack got messed up because I didn't buy the adapter for the 1/4 to 3.5mm and the weight of the jacks completely messed up the phone. I couldn't move a centimeter without that google prompt showing up. I still have this issue with my second v10 but it has drastically reduced the prompt now that I use this adapter.

    Sorry if you tried this. Only way I could replicate was saying "ok google" after enabling it for wired headsets in google now . I'm coming from a Nexus 6 and that "ok google" voice command is very sensitive. On the Nexus you can have the phone always listening for it even while the screen is locked and off. I've had it triggered listening to music, podcasts, talking to people without ever saying "Ok Google". You can turn this off by holding down the home button and swiping up, then hit the hamburger menu in the upper left corner, settings, voice, hands free it will give you an option to toggle detection over blue tooth and or wired headsets. Or just turn the detection completely off.

    I've had everything even remotely related to "Ok Google" or "Google Now" turned off since I bought the phone, but it still pops up whenever my headphones are plugged in. Not only is there a hardware issue with the headphone jack, but there is a software issue whereby the Google voice search CANNOT BE DISABLED. You can prevent it from popping up when the phone is locked, but you can't turn it off for when the phone screen is on. There is simply no option to disable Google voice search completely.

    So, our only hope is that some inline adapter can be used to prevent this issue in hardware. I have a Digi-key order on the way, so I might be able to get something put together over the weekend.

    That "OK Google" thing never worked right for me. No matter how clearly or loudly I spoke/yelled at my phone. People would stare at me like I was some lunatic yelling at my phone. Mine too did pop up a couple times when I plugged in my headphones, not every time though... so that was the last straw. It was one of the first things I defeated when I got my phone.

    Settings => Language & Input => Google voice typing => "OK Google" detection

    From there, slide the "From the Google app" toggle to the OFF position.

    It hasn't bothered me in almost 2 months now.

    Success!! (as far as I can tell, anyway)

    I ordered some parts from Digi-key (an online electronics supplier):
    Tensility International Corp 10-00341
    Switchcraft Inc. 35LJNS (There is also a gold-plated part, P/N 35LJNAUS, but it was almost $4.50 more)

    I would have posted the links to the actual web pages on Digikey's site, but I don't have enough posts, so you can search for those part numbers if you choose to do this yourself. You can also look for similar parts or build the cable assembly yourself from scratch. I went for "decent quality" and "easy".

    I found through experimentation that the LG V10 utilizes the CTIA pinout order for 4-conductor headsets (there is also an OMTP standard that transposes the Ground and Microphone contacts that is used by some other phones/companies). This means that the V10 expects the Tip to be Left+, the first Ring to be Right+, the second Ring to be Ground (Left-, Right-, and Mic-), and the Sleeve to be Mic+. So, I connected the cable assembly's red wire to the tip contact, the white wire to the ring contact, and the green wire to the shield/ground/sleeve contact. The black wire I just cut off and didn't use, and the shielding from the cable was also just cut off so that it wouldn't make contact with anything (I made sure that the shielding wasn't connected to any of the plug's contacts before I did this... I did some reading online that told me not to connect the shielding to signal ground in audio cables).

    So, with a little hair pulling, a flux pen, some solder, and a soldering iron you can make your own hardware fix for this issue. Or LG could buy some headphone jacks that aren't crap.

    I also bought a second set of cable assembly/3.5mm jack so that I can play with building my own custom cable that has an Android-compatible remote on a short wire (that way I can add a remote to a normal pair of headphones, and the short wire would allow me to run a line for the remote from my pocket (where my phone generally lives) up to a lapel clip. The remotes that Android phones use introduce a specific resistance across the Mic and Ground contacts, so adding a couple of resistors (one for Vol+ and one for Vol-) and a button for play/pause/next/prev on a small circuit board should give me all the control I am used to getting from my Bose in-ear sport headphones that I use with my iPod Touch at the gym.

    You re CORRECT sir... the steps I outlined above most definitely do not work. I think I am tricking my V10 into working because the mic/volume-cabled headphones I own are for iOS (being a recent convert). So I think the V10 sees an iOS cable just like a simple TRS connector headphone without vol module although the mic still works fine which for me is really the important part. I am willing to bet proper android cabled headphones will have this problem for me as well. I was at Frys yesterday and I plugged in the Sennheiser momentum headphone demo board and the annoying "OK Google" thing kept popping up at random.

    So, could I purchase this item and get the same results? It seems all that needs accomplished is the reversal of the GND and MIC wires.

    Edit, it seems that this is a bad product, based on the reviews. However, if it does what it says is that what we need?

    Unfortunately, that wouldn't solve the problem. What our problem is is that the headphones we are using cause the GND and MIC wires to be shorted together (this is normal, and a phone should be able to deal with this without any trouble) and that the headphone jack allows the plug to wiggle, causing the GND or MIC (or both) contacts to lose contact with the headphone plug. This causes the phone to think that we are using a headset (instead of plain old headphones) and that we have been pressing the play/pause button intermittently. The "adapter" I created only does one thing: it prevents the MIC contact from ever being connected to anything. That is why I didn't attach the black wire in the photo to anything.

    If you could somehow open that adapter up and snip the correct wire, it may work, but it would ONLY work with a standard pair of headphones, not a phone headset with the mic and remote. You could also snip the correct wire in a standard 3.5mm stereo headphone (3 conductor) to 3.5mm stereo headset (4 conductor) adapter, but trying to open up one of those short cables, identifying the correct wire, and snipping it so that it doesn't ever make contact without messing up the other tiny wires inside would be more work than building a new cable from scratch.

    What that product you linked to does is adapt a phone headset for, say, an international model Nokia phone so that it would work with the LG V10. It wasn't built to adapt a normal pair of headphones to a cell phone. I have seen products that do add a remote and microphone to a regular pair of headphones, but the remote ends up too close to the phone to be useful and to use the mic, you have to clip a wad of the 3' to 6' of cable your headphones came with to your lapel where the mic is. That is why I would like to put a short adapter cable next to the phone, then run a separate wire up to the lapel for a remote and possibly a mic. I'm going to see if I can design a little board with three buttons , some resistors, and a mic on it that could be put inside a 3D printed case. Then I could attach that to my current version of this LG V10 "fix" and it would also be useful for other people who have perfectly working set of phone/headphones to which they would like to add a mic/remote. Even though those remote/mic adapter cables aren't designed to be useful, they would actually fix the problems many here are having with normal pairs of headphones.

    You could look for these search terms on Amazon:
    Scosche control adapter for ipod
    Griffin control headphone adapter for ipod
    Monster iSoniTalk Microphone Headphone Adapter for iPhone

    They are all listed to work for iPod Touch or iPhone, but they would at least work to fix this issue with the LG V10. The only issue you would have with their 'features' would be that the volume control buttons won't work with any Android phones (Apple uses some proprietary digital communications protocol for their volume controls, where Android shorts the MIC and GND contacts through different values of resistors to change the volume or 0 ohms to signal play/pause/voice search). If you can find one that is built for Android phones, that would be a better choice, but it was hard for me to even find these adapters for use with the iPhone.

    So, with a little it of testing and prototyping, I managed to put together a neat Headphones-to-Headset adapter that is compatible with most Android phones. I put another cable together basically the same way, but instead of leaving the black wire disconnected, I ran it and another wire from the GND terminal to a breadboard. On the breadboard I placed a small condenser mic, a few resistors, and three momentary pushbuttons. This gave me the ability to hit play/pause/next track/prev track/Google Voice Assist, Vol+, and Vol-, and I was able to voice dial my phone, have a conversation using the mic on the breadboard and my Sennheiser HD 650s, and listen to and control music using the Tidal streaming music app.

    Unfortunately, when I tried to create a soldered version of the remote/mic I ended up shaving a bit of insulator off the wire and by the time I had tried to fix it everything was completely trashed. So, I have ordered a few sets of new parts so I can try to put together a working prototype. If I can I'll have a really nice, high-quality headset adapter for my Sennheiser HD 650 headphones that I might be able to get worked into a small product run. A side effect of using this type of adapter would be that the problems we have all been having would also be fixed. I'd just have to figure out how to design a small PCB and a plastic case for it to live in.

    The only real solution I can see is sticking with audio hardware whose male plug connectors use 4 conductors instead of 3 sadly. Kinda interesting really how this was present as far as I know since the G3 but was never really fixed.

    Yeah, and it's sad because at the moment this phone is one of the favorites in a thread labelled "Best smartphone for audiophile" on the Head-Fi forums. It looks like there are several new phones in the works that are going the way of the G3, G4, and V10 that are pairing a quality DAC with the necessary amplifiers to drive high-impedance studio-quality headphones (which was my main reason for choosing the V10). I'm lucky that I treat electronics as a hobby, so I had the tools I needed to diagnose and build a fix for my phone, but most people don't.

    That said, would people here be interested in buying an adapter if I were to put some together? I couldn't find any forum rules other than the ToS for the site, so I'm not sure if it is against the rules to offer something like that for sale. I wouldn't know how much it would cost, and I'd have to find some parts that are less expensive (the parts I used for mine were bought out of convenience... I already had an account at Digi-key, and those were the only parts that came up that didn't look like cheap plastic Radioshack style connectors). If there is some interest, I will see if I can find a source of decent-quality connectors and wire that doesn't cost too much and try to come up with a price.

    I wonder if this is carrier dependent?
    I only have gotten the OK google thing 2-3 times ever. FWIW I use a 1/8M-1/4F Grado adapter with my traditional headphones. The only 1/8TRS phones I directly plug in to my V10 are various Jays in-ears and Bose sound true. Both of which have mic/vol cables intended for use on iOS-Apple... could this be the difference?

    I have been considering upgrading my senn HD558 cable to one with a microphone. Should I buy one intended for iOS or Android?

    One age old drawback to the TRS connector is it will briefly short the ring and sleeve when its inserted into the jack. Headphone amp designers (single ended variety) need to account for this when they are designing the circuit. The circuit needs to be robust and stable enough to handle the brief shorting. Doesn't seem like LG or the android OS has taken this into account. You would think deactivating "OK Google" detection under Language and input settings SHOULD kill it outright.

    I'd probably pay ~$7-8 for it, but no more. I now listen to my music through my computer at work, and listen on bluetooth in both cars.

    This is a hardware issue with the headset jack of the phone, but a software fix appears to be possible. It looks to me like a daemon (background program) that monitors the jack and tries to detect what type of plug has been inserted could be created.

    Detection should be possible, since an electret condenser microphone element will appear as a resistive load across the MIC and GND terminals of at least 1Kohm (a short of the terminals would appear as less than 1ohm, usually, and the Android specs require that the mic element have at least 1Kohm of DC resistance). Anything that is plugged in that provides an open or short circuit, which you would expect from a normal TRS stereo or TS mono plug, should cause the jack daemon to turn off remote control detection in software.

    I don't know why such a daemon isn't already part of the stock ROM from LG. The Android documentation clearly sets out what headset manufacturers must do to comply with Android's specs, and it is fairly obvious that the mic DC resistance was chosen for the purpose of allowing for automatic detection of the type of device that has been plugged in. If Android doesn't have a jack detection daemon in its stock AOSP build, then it would still be simple for a hardware manufacturer to provide their own. Android might not include one by default because the device running Android may not always have a headset jack. It's possible that it might be a set top box with only HDMI or an optical output, or a tiny computer with separate headphone/line out and microphone/line in jacks. That would mean that manufacturers who provide TRRS jacks for headset use should create their own jack daemon that is tailored to work with their hardware.

    Hope this helps. Maybe we should be beating down LG's door to get a jack daemon included. They already have the hardware in the phone to precisely detect resistive loads, because the phone can detect Vol+, play/pause, and Vol- signals, which are resistive loads of 240ohms, 0ohms, and 470ohms respectively.
