Does somebody have an advise which other smartphone company is the closest to the FP2? I just went to a store a tried some headsets… all without succes :frowning:
… at least the wiki is extended with models that don’t work


#32

I have also two simple HeadSets, which are not properly working with the FP2 but did it like a charm with the FP1 and another old Nokia phone.
I made some more research I want here to share and which I also sent to support.
The 3.5mm headsets are 4-wired (2xstereo sound, 1 mic, 1 ground) with a call button.

Strange behaviour includes:

  1. If I plug in the headset slowly I** can’t see any symbol** in the notification bar (maybe normal behaviour of Android 5.1 in contrast to 4.2, which clearly showed me If I have plugged in a headset or a headphone)
  2. During plugging in, I can feel different “snaps” according to the 3 black rings of the jack-stick which are connected with the outer contact of the jack.
    a) if it connects to the contact between 2nd and 3rd ring: my right headphones of the set begins to make clicking noises continously
    b) if it connects exatly the 3rd ring there is nothing to hear
    c) if it connects to the last contact after the 3rd ring: the clicking noise at the right headphone is back, just quieter
  3. If I only play music through the headset I basically CAN hear the music, but in a very bad quality. Only during pressing the CALL-BUTTON the sound is as expected!! Releasing the button, sound again bad!
  4. If I try to call through the headset the mic seems to work - but in an unexpected way:
    The headphones itself do not work (or extrem quietly). But during PRESSING the CALL-BUTTON I can instantly clearly hear everything correct (as Nr. 3 above). The MIC is working quite OK, but DURING PRESSING the CALL-BUTTON, the MIC is disabled.
    Thus it is not possible to make a normal call !!
  5. During plugging-in any headphone/-set one should care about to fully plug-in the jackstick, as the last 1mm needs some stronger pushing… see pictures
  6. If I plug-in the headset, the software makes different things.
    -sometimes a grey screen appears just announcing “Initializing” in the middle
    -sometimes the music player continues to play (could be intended behaviour)
    -sometimes the music player does not continue to play
    -sometimes it appears the screen from “Google Now - please speak now”

forum threads in connection: here, here, here and the semi-official list here


For me it seems that there is any contacts inside the FP-jack wrong connected.
OR: my headset is not suitable for the FP2. BUT: Why it worked without problems with the FP1 and another Nokia-phone?
Plus the (hopefully) software-side is not programmed fully functional…

Playing Music through other headphones (without any mic) works well!

Any comments ???
Cheers, Robert

My headsets are:
Nokia WH-102 HS-125: and
B7 ZTE Blade:


Headphone jack defective?
Headset remote buttons do not work
Headphone Jack too small for 3.5mm

Thank you for detailed information, Robert! I have delivered a support request approx. one week ago, still waiting for answer. I will supply them with your information, too. I have checked my FP2 more in depth, and it seems to the “little plate” at the entrance of the “hole” that “only” may have to be removed a little bit. But I do not dare to do that without having asked the support.
I will forward their answer, when arrived.
/regina


#34

I also did already wrote to support and pointing them to my post/this thread…
We will see, who gets an answer first…

About your idea about the “plate” - are you sure? Do you mean the black part of my close-up picture of the “outer contact”?
If yes: I think this is not the reason. Because if you look at my pictures of the jackstick without the FP-case: there is still some mm space at the outside, if the jackstick is connected properly.
IF it is about physical design: it would be more at the “end” of the hole" (=inside), as the jackstick stops there maybe to early (although there is a more deep hole inside, but which is smaller than the stick).
AND: normal earphone do work properly. So also the most inner connector is well placed and connected I would say.

I think the problem is more about a wrong (or different to FP1) connection of the individual contacts inside the jack or wrong recognition of the software or the dedicated audio-hardware…And I fear there will be no fix…What would be a high disappointment :-/

We will see.

I use an (few years old) apple wired headset which I also used with FP1. In fact I have two of these both of which I have tested on FP1 and FP2… THe audio out on FP2 is fine, but the mic appears not to work on either headset - when i have tried to use the headset for calls no one can hear me, although I can hear them. Removing the headset and going back to handset mic has always worked. FP1 I am able to make a call with headset audio in and out.


#36

Could you check, if you really plugged-in the mic COMPLETELY, as I made a picture in my post above?
As for my headset the mic works, the audio out not good if I plug it in very strong.
If there only 1mm is missing, the mic does not work, but the audio is OK (not perfect). Could you confirm or not?
Do you have a Call-Button? If yes --> how sound and mic is behaving if pressed?
You could also add your findings to the list here.


#37

Yes, it’s absolutely definitely plugged in completely - the plastic around the plug is just touching the FP2 external case (so it cannot plug in any more). No call-button, just volume controls. The audio out is fine, not had any issues with that (but have used it quite a bit for podcast listening).


#38

Hi, same problem here.
Bose noise canceling head phones, inline microphone worked fine on FP1U and doesn’t work on FP2. Headphones works fine, just mic doesnt pick up anything. Other headsets do work, just this one suddenly does not. It’s all the way plugged in, it works on other devices, just not the FP2. It does manage to pick up a sound when i click the volume buttons.


#39

Hey @dull: so you exactly have the same problem, including changing sound if the button is pressed. good to know.

Could you also provide the headsets (+ details) which do work with the FP2 (incl. mic + button) in this post and also here?
thanks!

Hi @therob,

The working model i have is an old motorola wired headset. I attached a picture to show its not really a hardware problem from my point of view. Left works, right does not.
I’ve tested with and without cover on the FP2 to test if it was the edge of the plug.
Problem remains in both cases, while it does receive some input if I press the volume buttons.

I

Its a pretty standardised principle, and I’m not going to supply the model numbers on some sort of buy list for FP2 headphones. People shouldnt need to buy new headphones due to the Fairphone. Just like they shouldnt have to buy new charger cables. The headphone brands that aren’t working are well known, also for complying with industry standards.


#41

I see your point and agree.
But this list is rather issue tracker to narrow down the problem and merely a buying suggestion. As far as I understood this.

Since this knowing the model could help to find and solve the problem, at least you could write to the support team and tell what works and what not.

What do you mean with this?


#42

Hi @therob

Its an issue with different standards, and it seems like FP2 opted for changing its position compared to the FP1. In most cases it seems like a converter cable would work, and this would be a better advice then to look on the list to buy a new headphone I think.


To make a list with random headphone and which standard they use doesn’t make sense. Also In my post to you I have given you the type of headphones I had available to me already. It really just seems to be that FairPhone chose to use a different standard to comply with.


#43

Yeah you are right @dull!

But did I missed this information? Because this was definitively not clear to my until now, but for you it seems very obvious…?!


So I guess we really have now the REASON of the problem, but NO real SOLUTION and NO OFFICIAL statement on this.
@Douwe, @borjan, @Esmee what do you think?

(Again the link to the semi-official list.)


#44

The headset jack is following the CTIA standard. This information is available on the website (both on the product page and on the webshop).
It has been there since at least the 16th of July (date of the first available capture). (The product page referred to the webshop page for the full list of specifications.)

If a device follows the Android wired audio specifications - especially about the remote control, it should work seamlessly with the Fairphone 2.


#45

As @borjan stated above: he confirmed that FP2 (only?) supports the CTIA standard.

Still open is, if the FP1 really only support the OMTP, what our experience would suggest? The FP1-specs don’t have any clue about this.

All headsets which do not work properly obviously implement the OMTP standard, where the pin for mic and ground are reversed
(I do not debate, why the world need 2 standards with that minor changes!
And I do not guess, why this was introduced!
But I do ask about, why FP1 and FP2 have different standards?)

So the last missing information is:
Is here any chance that a software-change can do the trick?
Or if CTIA standard is hardcoded in the hardware of the FP2 and cannot be changed (which I fear)?

Can anybody tell my, where at this linked page stands, that OMTP-headset do not work with android, or are even not allowed?
I can only read “OMTP … optional” and “CTIA … required”, but don’t know what this means.

Any help with this?
Is there any argument, why the FP2 should not support the OMTP?
Is it possible to mechanically support CTIA and OMTP at the same jack? (I guess no)


#46

Two topics got a bit tangled, the above 15 posts were moved here. My apologies for not noticing the derailment of the original topic sooner.

Original post:

There’s discussion about this over here, though I see you’ve previously replied there as well. In short:[quote=“therob, post:26, topic:12166”]
Is it possible to mechanically support CTIA and OMTP at the same jack? (I guess no)
[/quote]
No, but an adaptor should work (see the linked thread).
However, if, as the title of the topic suggests, you have both no sound and no mic, then my understanding is that this isn’t necessarily due to incompatible jack wiring. Hence this topic on zero functionality (not related to jack standards), and the other topic on non-working mics (which seems related to the jack standards).


#47

Still I find the non interchangeability between FP1 and FP2 not satisfying.

Summary of my problem: I have bad sound which becomes normal if the one call button is pressed.

IF only ground and mic pins are inersed between OMTP and CTIA and IF the call button connects these two pins it makes all sense to hear perfect sound during button is pressed.

And this supports my claim, that FP1 uses different standard as FP2, which is my main point of disappointment in terms of sustainability…


#48

Hey Rob,

Yup, I agree completely, very disappointed in this decision to back Apple’s dominating standard, over the previously used Android standard. Anybody with an android headset needs to buy a new cable, converter or headset.
I feel that they should upload an instruction manual to change the headphone’s jack wring in the phone, or should at least link to a tested an approved converter in the store.
Its really sad you have to spend more money to use a headset that worked with the FP1.


#49

If it worked on your FP1 perfectly you should be fine with the converter. Probably you can test it in a shop first before buying?

Reading a little bit about that as far as I understood the tendency of all manufacturers has been to change to CTIA for a while now. Originally it was apple but now it’s more or less the standard of up to date phones. About the reasons of course I have no clue.
Meaning that FP in this case was not following apple or something but it was the decission in favor of the more common, hopefully longer supported standard.

I bought the perfectly working “Sennheiser MOMENTUM In-Ear G” at a store today.
There I was told that nowadays basically all headset manufacturers try to comply with Samsung’s (Galaxy) standard when it comes to Android support…
So… it sucks that Apple swapped to pin connections, but I guess at this point it makes sense to have a new unified hardware standard, so that the difference between Apple and Android is only on the software side.
I think Fairphone made the right decision to use the Galaxy standard, even though I can understand the frustration of FP1 owners :frowning:

I added my new Sennheiser to the list:
