2.5mm heaset plug to 3.5mm audio computer jacks?

I bought one of these tiny wireless headsets,

Quite amazing, it does work as advertized, at least with my cellular phone. However I would like to adapt its 2.5mm stereo jack (3 contacts for ground, speaker output and microphone input ) to the 3.5mm stereo jacks on my laptop computer (for Internet chatting and Skyping). So I need some kind of adapter.

Is there such an adapter on the market? I did some Googling but no luck so far. I would prefer a prebuilt adapter otherwise I'll have to do it myself but in that case it wouldn't be as compact.

You don't say what country you're in, but Radio Shack should have a bin full of them. You plug the 2.5mm plug into a hole in the back end of the adapter, and the rest of it is a 3.5mm plug. You might want to check for "polarity", i.e., whether the mic and speaker contacts are different for your dongle and your laptop, in which case you'll have to do some hacking anyway. :-)

Good Luck! Rich

It's not clear to me what you want. Your cell phone has a 2.5mm jack. AIUI your headset has a 2.5mm plug. You want to plug the headset *plug* into your laptop's 3.5mm jack?

Sure. If there are standards, there's an adapter go go between them. That's the great thing about standards, there are so many to choose from (and so many people willing to take your money).

In any case, here is a 3.5mm plug to 2.5mm jack (I think that's what you want) for $5:

Here is its reverse (also $5):

Did you try; "2.5mm + 3.5mm + adapter"? ;-)

I did the reverse - took my old headset from internet chat days and modified it to fit my 2.5mm cellphone.

Bought a cheapo cellphone headset from the 99cent store, hacked off the cheap headset guts and soldered on the internet chat headset wires.

There's a ground, a mic line and a speaker line... trial and error, then soldered...

Sure I know about one 2.5mm to one 3.5mm adapters... however I have to go from "one" 2.5mm plug to "two" 3.5mm jacks. Somekind of Y adapter. Anyway I finally built it myself this weekend and it's working now. I also found out the company got a model for VoIP for computer use but it is not available (yet) in New York.

Thanks for your suggestions!

Ok, go from the 2.5mm plug to a 3.5mm jack, then get a 3.5mm 'Y' cable.
