Hermes Handsfree Modifications to 3.5 mm - 8525, TyTN, MDA Vario II, JasJam Accessories

Hi
I've modified my Orginal handsfree to give a 3.5 mm Stereo socket. This is the procedure:
1. Open volume control & mic holder from edges.
2. You'll find four wires to earphone on out terminal soldered to PCB.
duly marked R & L on sides and two common in the middle.
3. Remove the earphone wires. Fix these wires to a standard 3.5 mm Stereo Plug.
4. next get a cheap 2.5 mm to 3.5 mm converter which is available in India at no more than Rs.70.00.
5. We require 3.5 mm socket with housing from this converter. Take out the converter remove all connections.
6. Take a piece of 4 wire ribbon wire.
7. Connect as per drawing attached. 2 wires to middle terminal on original
housing --- to common terminal in 3.5 mm socket
one to L other to R terminal on main housing and to L & R terminal
on converter
Your unit is ready.
I'm using in with Sandisk in-ear plugs stereo headphone kit and works
fine . Mic also works so you can talk on phone and use it to listen music also.

Modifying head phones to get in-car DAB

I'm considering removing the ear-pieces from my Lobster headphones, and fitting a 3.5mm stereo line socket like this one: http://www.maplin.co.uk/Module.aspx?ModuleNo=1210&criteria=3.5mm stereo socket&doy=24m5 to the end which would connect to one of these http://www.coolsmartphone.com/index.php?option=articles&task=viewarticle&artid=421&Itemid=3 FM transmitters to get DAB radio in my car.
The reason for modifying the headphones would be to retain the antenna function of the headphone lead, which would be strategically placed in the car to hopfully pick up a decent signal.
What do you think?
Get yourself a jack converter
I've been thinking about doing this too. I've got a small (Lobby size) 2.5 mm jack to normal (iPod size) 3.5 jack stereo convertor from e-Bay. I use this all the time as I don't like talking 2 sets of ear phones around with me.

Presumably you can get a wire (normal jack female to normal jack male) instead of detroying your headsets!
I wasn't sure whether an alternative cable would work as an antenna for the DAB radio channels like the original head-set does.
I have two headsets, so doesn't really matter if I butcher one of them.
Can you confirm that when using a 2.5mm to 3.5mm adapter and alternative headphones, the DAB radio stations still work?
Thanks!
I think it is the best one.

iPod Converter

i was thinking about doing this, but i've heard that these fm transmitters really don't work that well?
From what I've read, just like most other electrical goods, some are good, and some are not.
According to this review http://www.coolsmartphone.com/index.php?option=articles&task=viewarticle&artid=421&Itemid=3 of the Audia X transmitter, the sound quality is "excellent", but I guess sound quality is quite a subjective thing, and what's excellent for one person's set-up may not be for another's.
The Audia X is now available in the UK from places like this http://www.intomusic.co.uk/scripts/digiana-audiax.asp
so anyone got this working?

For the best result you are better off soldering rather than plug in, wherever you can.
I am going to put two phono sockets on mine, to plug into Hi Fi so that I have DAB reception on stereo.

Yeah, thats the plan, remove the ear-pieces from the headphones and solder a 3.5 mm stereo socket on the end so I can plug in the FM transmitter.

I tried this method by buying this: http://cgi.ebay.co.uk/2-5mm-to-3-5m...6QQihZ015QQcategoryZ86541QQrdZ1QQcmdZViewItem
I've tried 2 types of headphones with this but the radio and tv function won't work - not enough signal.
So I guess it's back to the original plan of butchering the headphones.
Sorry didn't realise that FM trannie had a male plug on it. thought it would have a female.
Mind you, being a trannie, how can you be sure.
Got it working
I've just got around to giving it a go.
I bought my FM transmitter (Power Trip FM) from HMV, and it comes with both 3.5mm and iPod connections.
I used the stereo 2.5mm male to 3.5mm female converter I bought off eBay.
Plugged it all together and hey presto, TV with the sound coming through the car speakers.
I'm in a good DAB area, so the signal is fine - even better with playing DAB radio.
No chopping or soldering required!!!
ringp3ace, are you saying that you're successfully tuning into a DAB signal using only a 3 pole 2.5mm jack? From Aleemz’s experiments with this earlier in this thread I thought the conclusion was that this wouldn't work. You must be in an area of ridiculously good DAB signal!
kettle,
Yep.
lobster > 2.5mm to 3.5mm > PowerTrip = no problems.
I am in a good DAB area too.

FIXING 2.5mm TO 3.5mm CONVERTER OR MAKING UR OWN

hi guys here is a way to fix ur converter.
1. open ur Converter from 3.5mm side.
2. desloder all wires coming from 2.5mm side.
3. take a multimeter or continuity tester.
4. if multi meter, put it on diode testing mode.
5. hold one wire at a time and test it via multimeter(by connceting one end of mutimeter at 2.5mm connector and one end at wire)
6. note the colour and the corresponding connection on 2.5mm jack(where the multimeter beeps and confirm the continuity).
7. Do this for all 4 wires.
8. now u know that which wire is connected from which ponit(connection) of 2.5mm jack.
9. out of 4 wires 2 are for stereo sound, one is common and another one is for mic.
10. Here on my BA the wiring pattern for 2.5mm is 1st is mic, second is spkr, third is spkr, and fourth is common.(starting from silver/golden side see screen shot) as u hv noted the color and conncetion at jack.now u can identify which colour wire on ur 2.5mm jack respond to mic, spkrs and common.
11. Now on ur 3.5 mm jack side u have a mic a button and 3.5mm jack.
12. Button is for attending calls it has 4 conneting points.
13. connect the mic with 2 connecting points points of button (at similer side).
14. connect the another 2 points of button one with common wire(of 2.5mm) and and another with mic wire of 2.5mm. (step 8 helps u here)
15. Now on 3.5 mm jack u have three connections one for left channel, second for right channel and one is common for both.u can identify the common easily as in all 3.5 mm jack the last and larger conection is always for common.
16. connect either left or right connection of 3.5 mm jack with one of the spkr wire coming from 2.5mm jack.
17. do step 16 for another wire for remaining spkr.
18. connect the common of 3.5mm jack with the common of 2.5mm jack(which is one the button).
19. now test ur handsfree.
Precautions and trouble shooting.
1. Remove the enamel insulation from wires porpely else they will not work.For removing, either use some solvent or burn them slightly from edge.
2. Do not short the connections.
3. if ur able to attend the call but ur voice is not going to other side inter change the comnnection on mic cause mic contains a diode which remains in forward bias in only one direction of current. so interchanging of wire will give u opposite polarity which allow the forward and reverse bias in proper direction.
AWESOME!
WOW MAN!
cool guide, thx man! i'll try that as soon as possible...
cheers,krz
Nice!
Good!
thank you! I\ll try to DIY this for my toshiba G900, as I lost the adapter. I'll use a 2.5 mm jack from a nokia headset and a 3.5 mm socket
Great post! Nice walk-through.
Respect
Tnx man, this helped me alot!

are himalaya's & alpine's audio jack pinout identical?

can someone please confirm this? like himalaya's handsfree can be used on alpine perfectly
I believe that all htc phones with 2.5mm minijack are
at least i used my wallaby headset with my himalaya
heck i used the cradle too so that connector is pinout identical too
oic...
1 more thing, there's supposed to be output when normal 3-conductor stereo 2.5mm jack is plugged into alpine's 2.5mm 4-conductor jack right?
I recently bought an alpine set without handsfree, then I went on & bought 2.5mm -> 3.5mm jack converter but I hear no sound on earphone having it plugged in, I've shaved the plastic & made sure the jack is inserted fully I dun have a stock handsfree to test with... could be the jack's fault? wuuuu T.T
I used both a org htc converter and a noname with my himalaya and they both did the job

extusb changes?

I have a 3 in 1 adaptor in my car, charging, outputting audio and inputting voice.
This setup worked fine on my Kaiser. With the HD I plug it in and get a "Headset not supported error message". The audio will also not output through the extusb, and will only come out the 3.5mm jack at the top I believe.
So what makes mine different to the below? I can only guess that the pinouts differ for some reason? Has anyone seen a pinout diagram for the HD that I can compare with the Kaiser?
Pinout will not help. HTC simply is not using the audio pins of the ExtUSB on HD.
Any (eBay) vendor you see claiming their ExtUSB-[fill in your audio device] is compatible with HD is not well informed. (or does not want to be well informed)

It was indeed eBay, ive just realised I didnt actually supply the link when I referred to "the below", so well done on filling in the gaps!
Thats a pain in the arse. So the 3.5mm jack at the top can accept incoming voice (from the mic), as well as output audio? In which case I can't see a way of making any kind of car kit work for the HD...

i use a normal audio jack out into my car stereo audio inputs, i get calls/audio/satnav instructions etc through the car speakers (obviously have the stereo on aux so dont get the radio at the same time
the inbuilt mic seems to be adequate for both calls and voice command
if not and you are ok at soldering tiny wires etc, then you could do what i did with my old charmer......
i took the wired headset, cracked open the mic/button press> attached a 1/4" audio socket to the headfone terminals on the PCB and a car mic (£3 if you shop around) to the mic PCB terminals. tucked all the wires away behind trim etc and had a custom built integrated hands free car kit (at the time i didnt have audio in on car stereo so adapted some el cheapo "ipod" speakers as well)

[Q] i9300 audio port

Hi,
I have a problem with syncing channels from my S3's audio port to my motorcycle headset.
Here's the deal: the S3 and the Nolan audio system in my helmet both use standard 3.5mm audio jacks, but there are some differences in configuration that cause compatibility issues. Since the Nolan audio system is just an integrated headset (2 speakers and microphone) - a 4 pole (TRRS) 3.5mm cable is required.
Scheme:
S3 3.5mm female port <-male 3.5mm 4 pole -----cable----- 4 pole 3.5mm male-> Nolan audio 3.5mm female.
I bought a simple 4 pole (TRRS) male to male cable and plugged in but it doesn't work good because Samsung and Nolan use these poles on the connectors in different formation.
So my question is: does anyone know the formation of poles (which is ground, right channel, left channel and microphone) in S3 audio jack?
