Sigh... still no proper in ear headset (monaural) in sight... :?

2.5 mm to 3.5 mm adapters at Radio Shack

---

Beware of the Radio Shack adapters. They stick out and are easy to catch on a doorway as you walk through it. I did so a few weeks ago and the headphone jack no longer worked. The adapter male end bent back and damaged the phone female socket. The result was very quiet sound from the headphone jack, totally unusable for phone or music.

I sent the phone back to T-Mobile and they very kindly sent me a replacement. I bought a new Radio Shack 2.5mm male to 3.5 mm female adapter and the same day proceeded to catch it on another doorway, bending back the male plug, and damaging the phone female headphone jack. No sound again from the headphone jack. I will stay away from the headphone adapters from now on.

Phone speaker not working after using headphones - No sound

I had a similar problem (not the same). After using a 2.5 to 3.5 mm adapter my phone speakers and the mic didn't work anymore. I was about to send the device in, when I read about a solution (I think it was in XDA-Dev somewhere).

You'll have to gently move the headphone jack forward and back, twisting it a litte or even better use some compressed air blowing into the jack. It works best, if you to take out the battery and blow from the back.

My speakers work again, but the same thing happens now and then. It seems there is some switch inside the headphone/mic jack, which doesn't go back. That only happens when I use the adapter.

I realize that this is an old thread, but here is an idea for you. As far as I know, pretty much any 2.5mm headset should work. I don't use it for my phone personally, but I recently purchased a Plantronics Gamecon X20 headset for my Xbox 360 after my old one broke. Since it has a plain 2.5mm jack on the end, I thought I would plug it into my phone to see how well it worked. The answer, pretty well apparently. My wife said that it was really clear and, likewise, she sounded really clear on my end. It's going to be a little larger than the ones that have the mic hanging down inline with the wire, but on the other hand, since it's a boom mic the sound quality should be superior with less noise. I haven't tried it for listening to music so I can't vouch for the quality there, but since you are wanting a monaural headset I rather doubt that is relevant anyways. The headset was only $20 at GameStop and they had a used one for $10.

In your case, I would say that sounds like a bad adapter. I routinely use one in mine and don't have that problem. It's one of those nasty stick adapters though, so you have to be careful with them. I've seen some cable type adapters for not too much so you might look into one of those instead.

Found info which might help

HERE IS AN/THE ANSWER.


My WIZA200 and Sony P900 phone the mic headsets are compatable, even the answer button works. If you cant find what your looking for under the flavour WIZa or HTC etc... just look for what you need as a P900 type and you will be sorted.

I just checked the pinouts and this answers the very much asked question... what are the pinouts.... here they are....

http://pinouts.ru/CellularPhones-P-W...t_pinout.shtml

FOR WIZA AND SONY P900 >>>> 2.5mm 4 pole jack: PIN1 LEFT+, PIN2 RIGHT+, PIN3 MIC+, SHIELD(PIN4) GROUND. I just checked with multimeter and to get call answer pin3 mic and shield must short to signal the press of the answer button.

Just for reference Nokia 2.5mm 4pole jack is very odd... this is how they do it.

http://pinouts.ru/CellularPhones-Nok...t_pinout.shtml

on 4pole 2.5mm: 1=speaker+(positive) ### 2=mic+ ### 3=speaker -(negative) ### pin4 = mic - ###short mic+ and mic - to answer call

on 3pole 2.5mm: 1=speaker+(positive) 2=mic+ 3=shield(ground-negative) ### to answer call short speaker and shield.

See how they change their minds... first on 4 pole jacks answer call was on mic side short, then it goes on 3 pole jacks to short the speaker and ground to answer call... can these guys not make up their minds. Grrrr... totally baffling logic in this design, escept they can keep you buying specialised gear for each phone

Glad to see Sony and HTC used a more logical system and seem to stick to it. I suspect the HTC Touch HD 3.5mm is wired the same as the Wiza 2.5mm system just 3.5mm jack not 2.5mm jack.

Someone should make a 2.5mm 4pole to 3.5mm 4 pole converter to use old cherised headsets on the HTC Touch HD... know of any, anyone?

Another solution.....

I know this might sound odd but a simple solution is get your stereo headset & mic thing and cut the right earpiece lead off...

Now you may have to strip the wire a bit and wrap a piece of insulating tape to stop the wires inside touching, which will cause problems (crackling or loss of audio on remaining speaker most likely). Once the wires are safely insulated away, youll have what you are seeking, a monaural one earpiece mic heaset... saves having to buy one that your finding hard to do.

Seems a shame to sacrifice a stereo headset down to mono, but if thats your poison, go for it.

pinouts.ru is the shiz
Get out the soldering iron and make a frankenstien. I grafted a 3.5 female to my old nokia's pop port so I could hook it to my stereo (before I got a BT adapter) and to my amplified helmet speakers (that were sorced from a computer speaker set.) Before I lost the phone I was planning to add a 2.5 mono female socket for a lil clip-on mic I have. Point being, it's only 3 signals and a ground, should be able to come up with something.

ts worth having a go

Yeah having a go is definately worth it. I just utilised the pinouts.ru stuff and a bit of personal common sense knowledge of the wirings and managed to make myself a 3.5 touch hd 4 pole jack into a 3.5 3 pole jack which works ofr my aircraft. I can now fly and make calls through my pilots headset. It shows it can work. You arent dealing with any dangerous voltages... its all piddly "put it on your tongue and you wont get hurt" voltages... speakers and mics... all easy to work out. Worth having a go.
