HTC mini-USB to 4 pole 3.5 mm

Is there such a thing as a mini-USB to 3.5 mm 4 pole adapter that works for the HTC Touch? I want to use a 3.5 mm headset with it.

sure
expensys and most other online stores like it got them coming out their rear end

The same one that comes with Touch Pro should work.

Thanks for your suggestions, but is there something that is a bit more compact? Something like this but with 4 poles instead of 3: http://www.amazon.com/Headset-Adapter-PPC6800-Verizon-T-Mobile/dp/B0016D9URO

I have been looking for a 3.5mm headset (not headphones, the ones with in-line mic and the extra terminal), but none of them seem to work with the mic. I have one I got for my hermes a while back that has three inputs - HTC USB, proper mini usb and a 3.5mm headphone jack. Very cool for using with desktop speakers and charging or syncing at the same time, but no use if you are trying to use a 3.5mm headset socket from a Nokia.
However, I just found one on ebay that does seem to work with 3.5mm headsets. Ordered one from the US for £9 all-in, although there are some in the UK for £15+pnp. Search for "HTC Headset Adapter" and they come up.

One comment about these: HTC has started making 10-pin mini-USBs. The bottom row of pins are still used for communicating with activesync, but the top row is now for the audio and mic. Traditional 5-pin mini-USBs do not have the top row; hence they'll only work for activesync and not audio functions.
So if you buy a 3.5mm adapter, make sure it is 10-pin and not 5!

HTCext to 3.5mm audio adapter mic problem

Hi!
I have this for some time: http://www.amazon.com/gp/product/B0...&pf_rd_t=101&pf_rd_p=470938811&pf_rd_i=507846
(Actually, I baught it in a store so I'm not sure it's excatly the same but it looks the same)
Recently, I baught this one:
http://www.amazon.co.uk/Headphone-HTC-VIVA-exclusive-Duragadget/dp/B001LIM8F0/ref=pd_rhf_p_t_2
When I plug the old one in my HTC Touch Cruise and then stereo headphones, to it's 3.5mm jack (without microphone), I can use phone's mic and plugged headphones to talk.
When I do the same with new one I can't use phone's mic. I can hear the other side through headphones but I can't be heard.
What might be a reason for this?
And can I fix this problem somehow so I don't have to unplug headphones each time I want to talk if I'm listening to the music?
Thank you very much in advance!
P.S. FM Radio works with both adapters.

there is no std for 3.5mm mini-jack with mic included
the org spc is only audio out
some headset makers add another ring which don't interfere with the
left, right and ground connectors
but there is no std they can follow
thumb rule is if mic is not mentioned in relation with the 3.5mm adaptor
mic is not supported as they use the pure audio out mini-jack std
thumb rule 2 is if mic is mentioned but it's not the same manufactures
in both end they may not implement mic in 3.5mm the same way and it will
only work with audio out

Thank you for your quick answer but I'm not sure you understood me.
I do not use external mic.
In first case I use 3in1 adapter and my stereo headphone with 3.5mm connector without microphone.
In second case I use this simple in-line adapter and same headphones.
In first case, during call, I can hear the other side through headphones, and the other side hears me through built-in-phone microphone.
In second case, during call, I can hear the other side through headphones, but other side can't hear me.
In both cases FM radio works well. I mention this because I saw that mic and FM antenna are on the same pin in USBext (if that's important since I don't use external mic)

about fm then all it needs is an antenna connected to to it
any stereo maybe even mono connected with a wire will do
heck you can cut off the airplugs from a cable and use it for fm
normaly when one connects a headset speaker and mic on the device itself
are muted
even if it's a headset without mic so cool that your fist case works at all

This first one adapter is original HTC. It has 2.5mm, 3.5mm, USBext for data and charging and USBext for headset connectors. And unfortunately it is too big for any other use except in car (to connect to car's audio aux input) or at home (to connect to home AV reciever).
So I baught this cheap simple in-line adapter. And it is suprisingly well built. And it works great as stereo adapter. Only problem is that it turns of microphone.
Anyhow I did some additional testing.
I tried SE Xperia X1 since it has built in 3.5mm connector. and it works like this first one. That means microphone works.
I also tried plugging this first adapter into my touch cruise and then plugging this second adapter into it's USBext for headset. The result is the same as if I plug second adapter directly into touch cruise. Microphone doesn't work.
Interesting thing is that in all cases (including Xperia) when I listen to the music with external headphones soudn comes only out of them. But when phone starts ringing sound comes from both headphones and from built-in-phone external speaker.
!!! Maybe the most important thing is that microphone doesn't work even if only second adapter is plugged into the phone, without headphones plugged in it.
Obviously this second non-HTC adapter doesn't work as HTC originally planned that kind of adapter to work and now I need a way to fix this.
It seems to me that this adapter is maybe stereo adapter with mic, but I don't have that kind of headset to try it. And if I had it I'm not sure it would be the right one since there's no standard for them.
As I see it when I plug in adapter phone somehow detects it and changes some registry key which mutes microphone.
Does anybody know what to change in registry so that phone doesn't mute microphone?
Or how can I see what changes in registry when I plug in the adapter?
Do you think if I manage to fix this, will that affect bluetooth headset also?
Thank you very much for any help!

Arc S earphone jack configuration

does anybody know of a software solution like an app or some other hack to make the earphone jack on the Arc S compatible with aftermarket earphones having a inline mic?
background --
The headphone jack on the Arc S is different from those found on motorola, iphone or HTC phones. The four connectors have the same configuration for the left and right audio channel but the connections for mic, ground are interchanged. 99% of the earphones with inline mic available in the market are made to the iphone specs and hence are not compatible with SE arc s. I have these ones and these, but when i plug them into the phone it just says "accessory not supported" .
I had the same problem with my last phone samsung wave which also has the flipped ground/mic connectors. The earphone that came with that phone also work on the arc.
There are cables available that fix this problem -- http://www.amazon.co.uk/gp/product/B005I0GHV8 (I have bought this one)
http://www.meelec.com/MEE_TRRS_Adapter_for_P_Version_Headphones_p/adptr-trrs-35.htm
http://www.kvconnection.com/product-p/km-354r2m-r3f.htm
galaxy s users can use an alternative voodoo sound driver to mke the earphones compatible without the need for additional adapter cable.
can something similar be done for Arc S? , (I have bought one of those adapter cables but it sucks to have it dangling from the phone all the time)

base on my experienced, you can try this.
SE supply the wired Handfree kits right? along the kit got
1. stereo jack with mic inline (you should notice the jack has 4 metal/copper connection to be plug in to the phone)
2. in the middle have mic and an answer button + another Stereo jack receiver,
3. after that, then you will have a bit short wire stereo earphone with a stereo jacks but without the mic inline wire (you should notice the jack has only 3 metal/copper connection)
you should connect your wire input device to the stereo jack after the mic, because after the mic only the circuit will only supply sound output voltage (+ left, + right & -ve for both earphone)
...i am sorry for my bad English
goodluck

@putrabiru
you seem to have misunderstood the problem
earphones that don't have a mic in them(3 rings on the jack) already work fine if connected directly to the phone.
I am looking for a way to make earphones with inbuilt mic(4 rings on the jack) work with the arc without an additional piece of wire between the phone and the earphone jack.
So i am basically looking for a way to make the phone treat the mic and ground connectors opposite to how they are set up by default. This will definitely require a kind of mod to the system files of android or the drivers. I've even read about other users of samsung phones who opted to physically replace the headphone jack unit on their phones with standard configuration ones!
Sony should have kept the configuration the same as how most earphone manufacturers make them.

Sony actually uses the agreed OMTP standard for mobile headsets. The reason for all these problems is nothing other than the recent popularity of crApple.
Just get a cheap OMTP adapter off ebay. You should be able to find one by searching for something like "Motorola headset adapter" etc.

As Paul stated, Sony Ericsson actually followed the standard, Apple did not. I would suggest to look for an adapter if you want to use "iPhone compatible" headsets.

Try to plug only the first 3 pin leave out the last it works for me

your thoughts on audio through 3.5mm dongle?

Hoping to get your thoughts on audio through 3.5mm dongle since I just can't seem to find anything at all.

Audio should be identical to the P2 XL, look there

It sounds the same as the 2XL: no problems using the USB-C to 3.5 mm dongle (that was included with the 2XL). Sounds the same as a regular 3.5 mm headphone jack. I never had an issue with the official converter. If you buy a cheap one from Amazon, it won't work (tried that once). It has to do with what is enabled in the cheap converters, etc. I don't remember, but I learned my lesson.

It works well. I was using it on my LG G6. my head phone jack on the g6 must have been broken because i would loose sound in one headphone and sometimes it wouldn't recognize them. Interestingly I went through 3 replacements of that phone and all of them had that same problem. But with the connector it worked perfectly. it is a pain in the butt to use and a stupid concept, but a stupid concept that worked better than the phone's jack.

USB C + 3.5mm Cable?

I bought this "3 in 1 USB C Aux Adapter" cable to use in my car but it doesn't seem to work right with my car for some reason.
When my Pixel 3 is plugged into the USB C side it only outputs the left channel
When my Pixel 3 is plugged into the 3.5mm w/ an adapter it only outputs the right channel
With my iPod Classic plugged into the 3.5mm side it seems to output both L and R channels
Anyone know of a similar type cable that definitely works with the Pixel 3? I don't really want to have to use an adapter.
::EDIT::
Well, slightly embarrassing but I actually wired up the aux cable incorrectly in my car. All is well and the cable works properly.

Let me preface...I'm definitely not an expert in the whole audio conversion area. I did start doing some light research a while back regarding USB-C --> 3.5mm adapters because I noticed that the dongle provided with the Pixel 3 caused sound quality issues with my 3.5mm Bose buds. I fly on airplanes a lot and noticed the sound output volume is significantly less with the dongle and 3.5mm headphones than using the USB-C Pixel buds. From what I've been able to gather is that the digital audio converter (DAC) chip built into most of these dongles is garbage or nonexistent.
Regarding the 2-in-1 adapter / chargers...I was also looking to buy something where I could listen to my 3.5mm buds and charge my phone at the same time BUT I stumbled across some article that basically said none of those work. If I remember correctly it had something to do with the phone itself, I think it was software related?? Maybe do some searching on this but I remember reading enough stuff where it sounded like a scammy product line so I didn't purchase. Maybe this has something to do with your L vs R channel issue??
Back to the regular dongle converter...you know how things are on Amazon sometimes, 3rd party vendors can be shady and say something is higher quality when it's really not which has made me hesitant to pull the trigger on a slightly more expensive dongle. That said, I finally purchased one today that is definitely a bit more expensive than others but it seems legit and I've found reviews in other forums referencing it. Here the link: https://www.adv-sound.com/products/accessport-lite (it can also be found on Amazon).
It should arrive in a few days so I can report back but I'm keeping my fingers crossed that audio output volume / quality isn't lost like it is with the standard dongle.

Alright, the Accessport-Lite (APL) converter arrived today. Here's what I think...regular 3.5mm headphones (I'm using Bose buds) into APL into device are definitely higher quality sound than using the converter that came in box with Pixel. You can hear more background noise, overall it's more crisp and max volume is a little bit louder, not as loud as I was hoping for however but an improvement that will make a difference when flying.
Another option...I picked up a 3.5mm splitter months ago so two people could listen at the same time. I noticed that 3.5mm headphones into splitter into Pixel box converter into device actually has higher max volume than simply headphones into Pixel box converter. Go figure. Splitters are really cheap at electronic stores. Although, I would recommend buying one from the audio equipment section as opposed to the phone section. They really upcharge you for the same exact thing that's supposed to be "specially made for a phone" which is garbage.
I also tried 3.5mm headphones into splitter into APL converter, sound quality wasn't noticably better than just APL. If anything some of the crispness seemed less.
Pixel Buds straight into device remain the loudest option. However, they do not cancel or shut out loud background noise like when flying so peak volume means nothing.
Long story short...I'm decently satisfied with the APL converter. Didn't blow me away but you can tell it's quality made and every but counts when trying to overcome loud airplane noise.

Thanks for the heads up on this adapter! Definitely good to know about. I've seen good things about the Apple adapter too but have also seen reports of it not working properly? Have you tried that one? At $9 it's definitely on the cheaper end.

I've been using the Apple USB-C to 3.5mm adapter for half a year. I like it: the Google adapter was too loud on lowest volume, and had an issue with echo in calls when using earbuds with a mic (Shure SE215). The Apple fixes all these issues and is smaller and lighter.
