2.5 jack to seperate mic & headphone on SDA

imported_hyedipin · 12-11-06, 10:36 AM

As you know SDA has 2.5mm jack and comes with a stereo headset which has a earphones + microphone hard wired. So that tells me it's jack is three stage (Stereo Left - Stereo Right - Microphone Mono) so if I plug a stereo 2.5mm jack in there, it might turn into a Stereo Left - Microphone Mono.

What I want to do is to retain it's setup, but get a connector that will seperate the microphone input & allow 3.5mm or 2.5mm female or male jack at the other end.

I want to hook up the earphone end to speakers and have a seperate microphone hooked up to it.

Any ideas?

Get out your wire cutters and buy a few parts at Radio Shack. Use a simple ohmmeter to perform a continuity check on some partially-stripped wires. Of course, somebody does make a splitter, and this one is on sale: 2.5mm to 3.5mm Audio Jack Adaptor with Mic for cell phones with 2.5mm jack ($6.95 plus $3.95 shipping for $10.90)
or on ebay:
eBay: Stereo Adapter 2.5~3.5mm w/ Mic BlackBerry Pearl 8100 (item 300054586790 end time Dec-28-06 07:52:38 PST) ($5.99 plus $6 shipping, $11.99 total)

I searched Google: 2.5 mm 3.5 stereo microphone adapter - Google Search
And I think if you have a stereo 2.5 headphones only, it should come out as stereo in that jack.

I knew someone had some idea what I was talking about :) Thanks Karl.
I actually ran into few of those, I would still need the mic jack to be a separate input so that I can pull the mic & speaker output to two separate locations. With most of those I found, mic is still attached to the cable. I might be able to strip one of those, but while doing I can mess it up.

I will search a bit deeper to find if there is anyone Y shaped for individual mic input and speaker output. If you have seen one like that, please let me know.

Edit: This might be it.. PPC Techs PPCPADPT12 2.5mm to 3.5mm Mic/Audio Adaptor Larger Image - MobilePlanet Inc.

Also, I might be wrong about 3 part 2.5mm jack, it could be 4 part (4 conductor), I will have to check the headphone/mic set that came with my SDA which has answer,mic,stereo earphones.. so it could be 4 conductor.

I saw the PPCtechs part, but didn't include the link because it was $22, way too expensive for a basic splitter/adapter. Your plug will be a 4-conductor plug if it has stereo plus mic. The conductors will be L, R, Mic, and Common ("ground"). I think Answer button just shorts Mic to Gnd momentarily.

I will try to set up this with a stereo, hook up the connection to stereo's input and connect mic to the split end. I am wondering if there will be a lot of echo with this set up..
