USB-C headphone adapter inline mic issue? - Google Pixel 2 Questions & Answers

I've had a consistent issue with my Pixel2's headphone adapter.
When on a phone call with headphones and an inline mic, I hear the headphone mic fed into the headphones, but ONLY when on a call in the phone app. (Mute button still feeds audio)
Does anyone else have this problem? I have a thread of users on a google forum all with the same problem, new Dongle replacements and even replacement phones doesn't seem to fix it.
Is this a known issue? Should I return my phone and try again?

My inline mic on my headphones doesn't work. I don't know if the standards changed or what is the cause.

This is the thread listing other people with the same issue. I'm surprised this hasn't surfaced on XDA yet.
I've tried numerous headphones, confirmed they work on other devices (worked on my nexus 6p and lg g3, and laptop), and it isn't even an issue when using VOIP / skype / slack.
The problem only occurs when on a phone call, and persists even when on "mute". There is almost no delay in the sound feeding back into the headphones, it isn't a carrier issue (as google tech support already suggested, SMH), so it must be isolated to the adapter AND/OR phone app.

Why some headphones don't work with some phones?

Hello.
I'm trying to figure out and possible find a solution for why some headphones don't work with some phones?
For example a very well known brand Scullcandy. Their line of Skullcandy FIX Bud headphones work fine with Galaxy S2, but don't work with Galaxy S3, they also don't work with LG Nitro HD.
On GS3 they work for media playback, but when trying dial out or answer a call, the phone totally disconnects the headphones, the icon that shows when headphones are plugged in is no longer showed and at that point one has to physically re-plug the headphones in order to use them for media playback.
It does sound like phone's software issue, I sure hope so and there is a way fix it...
Another phone I had bad experience was LG Nitro HD. Even though the phone is totally waste of money it don't accept any iphone type headphones, they might work for playback, but mic or buttons don't work.
So what could possibly causing this issues?
I've tried post on phone related sections, but got no answers...
I also tried contact Samsung support regarding this issue, but they simply blew me off with "we don't provide support for 3nd hardware". Now I'm waiting for an answer from Skullcandy support.
Any ideas?
Thank you.
Probably the 3-pin layout of your phone. some are really weird in the way they work

There might be a couple reasons. The first is the connector. Some headsets use a three pole connector while others use a four pole connector. The other issue will likely be he pin out. The headphone jack might be a standard mechanical interface but not electrically. Both are hard problems but an adapter cable might help you.
All headphones connectors in question are 4 pin type, without using micrometer they look identical. Since all these headphones works fine in mp3 players, where only 3 pin connectors used, means the 3 out of 4 pins are in proper places and connected properly inside the wire.
So, without taking headphones apart it seems physically there is nothing different between them.
In addition, if there would be something physically wrong, it would not explain, why SGS3 sense when Skullcandy headphones connected, it shows headphones icon, but when a phone call initialized it "forgets" about it.
It sure seem to me like software related..

[Q] Bose QC15 noise canceling headphones not working with Moto G

Hi all, I got a Moto G 8gb from Phones4U, and my Bose QC15 noise canceling headphones made a nasty clicking noise every time they were plugged in. The clicking would happen no matter if something was playing or not. Nothing would play out of either channel, and the software would randomly pause whenever they were plugged in, as if they were being unplugged. Various cheap earbuds worked, but not my QC15s. I factory reset it three times, and obviously tried the headphones on about a half dozen devices, including a Galaxy IV, iPhone 5C, Nexus 5, my laptop, my desktop, and an old iPod Classic -- all worked perfectly.
I took it to Phones4U and exchanged it for another model, which had the exact same problem. We tried a 16gb version and it had the exact same problem too. Then we tried it with various other phones and my QC15s worked, so they told me that my headphones must obviously not be compatible with the Moto G line. Then they said I wasn't even eligible for a refund because it was about compatibility, not a defect. I raised hell and finally got them to refund it, but now I don't know what to do. Anybody else have noise canceling headphones, especially the QC15s, that they have successfully or unsuccessfully used?

You were probably a bit hasty returning the phone just for this, but you're right there's something screwy about the Moto G's handling of wired earphones that are more complex than basic stereo. I can't get any 3-button remote headset to work with it properly, for example. No doubt Motorola will deal with this in future updates ... unless they only want us to buy the Sol Republic Jax earphones, which would not be good ...
I'm also surprised you got a refund, as Motorola doesnt claim compatability with your headset. Also surprised that Phones4U now have 16GB in stock

Just for the record I have a 16gb Colors edition from Brazil and I use a Sennheiser bluetooth headphone with my Moto G (PX 210 BT) and it works beautifully!
I can use all its buttons with no problem: play/pause, volume up and down and skip track forward/backward.
One interesting thing I noticed was: the headphone did not perform very well with Google Play Music. Both sound quality (it would constantly click during playback) and the buttons (play/pause button would only work with screen on) were not up to standard.
However when I installed my player of preference, PlayerPro, and messed a little bit in the settings of the app with audio priority and with the keyguard settings both audio quality and buttons were working great!

Yes, bluetooth is another matter of course. But I guess he has a reason to be sore when those wired Bose QC15 headphones cost twice as much as the phone itself
Workaround to make them work
I have the same problem connecting my QC15 with moto G. With some experimenting I somehow made them work and they are perfectly fine now. Follow the below steps to make them work with your phone.
1. Disconnect the headphones to the phone and start music on any player(Google play or your choice) on the phone.
2. Once the song starts playing insert the headphones into the jack. Imp Note: remove the headset part from the wire.you should only insert the wire without having the headset piece.
3. Now the song will continue to play. Now switch on the headphone and insert the wire into the headphone. It should work now.
I know this shouldn't be the actual scenario, but engineers at Motorola have made up some mess which cannot be cleaned up now with respects to hardware. The phone is little wierd on headphones port. Its not working with aux cables in my car too
I have SMS street by 50 cent and every thing works fine. skip/pause and previous track

Same problem
I've experienced the same problem with Bose QC15 and the Moto G. Motorola support were rude and unhelpful, first assuming that the QC15 were bluetooth and telling me flat out that it was not a fault of their hardware. Eventually I got a ticket raised so we'll see what happens. Not holding my breath.
bonthukarthik, your fix works - thank you for sharing - although I must add that this step has to be repeated whenever playback is stopped or paused (including when Spotify plays an advertisement). If I find anything out from Motorola, I will share it here.
I just got some qc15's and they only worked out of the left ear with the moto x. I used the work around above and they now work. weird. play/pause button now works but the volume does not on the inline headphone controls.
What kind of connector this headset/headphone has?
CTIA or OMTP?
I have skullcandy 2xl single button headphones and it doesn't work
when i attach the headphones the music pauses
Confirmed
I can confirm this issue with Moto X and also the workaround. I have contacted Motorola but so far no luck in getting through to someone who can open an issue internally
Skullcandy not working
Have the same problem
I have the skull candy inkd 2
It only works when its 3/4 inside but when I push it all the way in a clicking noise plays
Please find a solution
Hi.
I just got a moto g, I have a bose qc3 and the same problem.
It seemed tome that it seemed to me that it was connection or impedance related... so I tried a few things.
The best way I found to make it work fast is plugging it in using the airplane jack adapter. It works perfectly fine but the remote won't work.
I guessed that it means that it's remote/impedance related.
Like it was said before, unplugging the jack on your headset, playing something on the phone and plugging it it afterwards works too... But I really don't know why !
Any clues, anyone (with advances electronic skills)?
With my former android phones I had troubles using the answer/play remote on some headphones/buds, but never like that. It was allways clear to me that iphone and android headset/buds remotes work in a different way, and sometimes even differently depending on your android model or brand...
My guess is that using a cable without a remote will work... but it's be nicer to have a working remote.

I found something, just a clue, I don't mean it'll work for sure.

Alright here are some more details / partial solutions :
- If you plug your qc using the jack with the remote/mic and the airplane adpter, the sound sill work, but you'll lose the mic and commands. Basically it's the same as if you plugged it in usgin a "regular" jack cable (that bose sells, or used to, btw)
- if you use the "play and then plug jack in headset" workaround, sound will work, the main button too : it'll play/pause, but if you stop and quit tha music app, the problem will come back
- almost the same with a call, if you call your phone and wait for it to ring before pluging the jack into your hedset the sound will work both sound and mic, but the button fonctions are weird : at first it'll aswer the call, but afterwards it'll work as an on/off switch for the mic.
- Best solution I found : when you plug your headset and have the parasite problem, just press the main button on your remote, it'll stop the problem... but the button won't work anymore, either to answer/hangup or play/pause. I use this solution ftm, even if I don't think it's good for the headset to have this clicking parasite, and I'm still waiting on a way to make everything work all the time.
Any ideas ?

Have you tried with a CTIA to OMTP converter .
Hi, thanks.
No, i should, but I thought that all android phones were ctia now... I don't have my moto handless kit with me, but I'll try it with my gf's xperia sp to see if it works with it, since my bose headset works perfectly with the xperia.
Anyone knows if the moto g is ctia ?
Any other ideas ?

All Stereo Head phones normally use a 3 Pin Jack, Cell phones use a 4 pin, I found this out before with some other audio products..
I confirm all the informations about the problem and the workaround concerning a Moto X and the QC15 I just got. I hope a solution will be found. Does anybody tried that amazon product ?

I have a Droid Maxx and the QC15. The android inline remote & mic kit from Amazon have the same problem as the iphone cable that comes with the QC15 headphones. Quite annoying. Also, I can't get the workaround to work. No matter what I do, I only get sound from the left speaker.
I had a similar problem (no audio, weird noise in right ear) with Moto-G and QC15. The workaround that succeeded for me was to change the headphone gain from Hi to Lo. The gain switch is in the plug that connects the wire to the left earcup.
This supports the suggestion that the issue is caused by some impedance measurement routine on the phone.

My Bose QC 15 headphones had a problem with the iPhone-compatible cable, that includes a volume control and microphone.
Another "audio only" Bose cable that omits the volume control and microphone is also available off eBay for ~$10.
I asked Bose for an Android-compatible version with volume control and microphone, and they said they're "considering making one".
normally the headphone jack provides a link for headphones with e.g. microphones or buttons (to accept calls), which uses the same wires as for the audio.
the effect can be triggered by e.g. dirty connectors. so I once had a new pair of headphones and on the connector jack there was a bit of debris (glue or whatever left). they did also cause the phone to pause/play every now and then. so I cleaned them and then they did work without problems. also sometimes the connectors have to "grind in" until there is a good electrical connection.
however as it is steadily pausing/playing on your iPhone 5 headphones, I dont think theres an issue with the connection itself.
it might just be that the iPhone 5 headphones are trying to "communicate" with your phone, which it doesnt support and therefore is misinterpreting it as the start/stop commands. you cant do anything about it I guess.
(except dont buy apple products anymore )

Headphone microphone doesn't work

When I use my OPO with headphones and get a call, I can hear the person through the headset but the mic doesn't work/pick up my voice and neither does the phone mic. I have to take out the headphones and phone the person back for them to hear me.
Does anyone else have this problem? I tested them on my N4 and the work fine.
What headphones are you using? My Pistons work fine.

A lot of people are having this problem. It has to do with the TRRS OMTP vs CTIA configuration (left,right,mic,ground vs left,right,ground,mic) and maybe something to do with resistances as well. If your headphones were designed for "iPhone" chances are the mic won't work. People have tried using the CTIA OMTP adapters, but that hasn't worked. There are some headphones that do work, (like the Pistons mentioned above). One thing you can do to fix this problem is download soundabout from google play (https://play.google.com/store/apps/details?id=com.woodslink.android.wiredheadphoneroutingfix&hl=en). In the wired headset section, you can tell it to ignore the mic in headsets, this way it will still use the builtin oneplus mic instead of your headphone mic. Not a good fix, but it's all we can do until they come up with a patch. This is a huge issue that's been on Jira, but there's no indication if this will ever be fixed.

Wired headphones : weird issue

Hi dear friends,
I'm having a weird issue with wired (jack) headphones during calls : I can hear my own microphone !
For example during a call, if I'm in windy conditions, I can hear the wind.
During such scenarios, my phone is in a pocket or in a bag, so the mic I hear is the one on the headphone's cable.
This problem arises with either the headphones provided with the Pixel, or with any other wired headphones kit (I've tested with a Samsung).
On headphones with volume control, I can even hear a loud sound when volume up or down ...
And this issue is here out of the box, without any APP installed.
My phone has already been replaced by Google support, but the issue is still there one the new one.
Does any of you Pixel 3a owners, have seen such an issue with its phone ?
This is normal operation.
If you are wondering why the noise cancellation isn't working better, you have to understand how it works. It compares the audio from the mic on the headphone wire with the audio from a mic(s) on the phone. Anything that both mics pick up is cancelled by the noise cancellation software because it is considered an "outside noise". But anything picked up on just the wired mic is considered part of the conversation and won't be cancelled out. That means if your phone is in your pocket and it isn't getting the same wind noise (for example), then the phone will not cancel out that audio because it's only being picked up by the wired mic and not both mics.
Hopefully that helps. If you want wind noise to be cancelled out, try holding your phone in your hand and see if that helps. But the wind noise may not be picked up even then depending on which way the wind is blowing vs what orientation your phone is being held in, so you might have to hold the phone a couple of different ways to find one that works the best at that time.

Thanks for your reply
My guess is that this issue is not related to noise cancellation.
1) I've indeed mention that, in my test scenario, my phone was in my pocket. But I can remember of several times I was holding the phone in my hand, or phone was lying on a table, and even then the sound captured by both mics was audible by me.
2) When I'm in call with another person, and I'm hearing the wind in my own mic, the other person does NOT hear the wind.
Isn't anyone here using jack wired headphones ?
