General

alright thanks bob and dj =P

Cool... you lucked out..! They designed your headset much more practically than some, and put the more common stereo plugs on both the mic and headphones.

Sorry about all the confusion- to answer your original question.. yes..! A stereo cable will work just fine.

(Actually the black rings are plastic insulators. The "sleeve" is the metal piece between the two black rings, the "ring" is the metal part attached to the plug handle and the "tip" is the round metal, umm.. tip. That gives three connection points, allowing left channel, right channel and ground. Just by way of "fun facts".)

I feel asleep last night before I could edit "Go PM BobR." xD

rofl this is way more confusing than i thought it would be... never thought one of my threads would be subjected to the "bobr essay" =P

anyways... as for the microphone jack... it looks exactly like the headphone jack..., the tip, and 2 black rings... is one of the black rings the sleeve?

edit: newegg has some pics of the jacks on the g330 which is what i have http://www.newegg.com/Product/ImageGallery.aspx?CurImage=26-104-319-04.jpg&Image=26-104-319-01.jpg%2c26-104-319-02.jpg%2c26-104-319-03.jpg%2c26-104-319-04.jpg%2c26-104-319-05.jpg%2c26-104-319-06.jpg%2c26-104-319-07.jpg%2c26-104-319-08.jpg%2c26-104-319-09.jpg%2c26-104-319-10.jpg&S7ImageFlag=0&WaterMark=1&Item=N82E16826104319&Depa=0&Description=Logitech%20G330%203.5mm%2f%20USB%20Connector%20Circumaural%20Gaming%20Headset

Well, umm... a stereo cable -might- work ok... but... headset microphones typically are "mono", which means the plugs and jacks have only two contacts, while a stereo plug and jack have three. Depending on the phase of the moon and how lucky you are, the two contact plug on your mic may work ok with the the three section jack on your stereo extension cable, or it may short out and prevent anything from working.

You'd really be better off getting a mono cable for the microphone. Something like this: http://www.cablestogo.com/product.asp?cat_id=2002&sku=40626
although I don't know why this particular brand is so pricey.

If your headset is like mine it has two separate plugs on the cable, one for the headphones, one for the microphone. If you hold them up next to each other, you can see that the microphone plug has two separate metal contacts, the "tip" and the "ring" (the main part of the plug). That's because there's only one audio signal coming from the microphone.

The headphone plug has three separate contacts on it, the "tip", the "ring" (the back part of the plug) and the "sleeve" (the middle part of the plug). That's because there are two audio signals going to the headphones, the left channel and the right channel.

If you plug the two contact plug into a three contact extension cable, the plug may short on the jack and keep the microphone signal from working. Sometimes you can "adjust" the plug in the socket to make it work, but chances are it will jiggle while you're using it and short out again.

If you already have a stereo extension audio cable, try it and see if you're lucky.
If you don't already have the cable, buy the right thing and get a "3.5mm mono male-female extension cable". Make sure it's not marked "stereo".

EDIT- Upon further investigation, it appears male-female mono extension cables are hard to find. Odd. What's easily available are male-male "patch cables" with two male plugs. These are apparently abundant and inexpensive. http://cgi.ebay.com/10ft-3-5mm-1-8-Male-Male-Mono-Audio-Patch-Cable-/170507860780?pt=LH_DefaultDomain_0&hash=item27b30f7b2c

You can make one of these work by adding an additional "female - female adapter" such as this: http://cgi.ebay.com/3-5mm-Female-3-5-mm-Female-F-F-Audio-Adapter-Coupler-/280540850644?pt=LH_DefaultDomain_0&hash=item415189a9d4

It'll still work although you might get a weaker signal due to the increased electrical resistance. TRS cables for the most part are some copper wires (2 I think) with the 3.5 connector.

For that reason, you can even make your own just by buying the wire and connector.

nope, its just a typical headset mic

Most likely. Does the mic happen to have an amplifier?

typical 3.5mm pc audio jack

What kind of jack is it?
There usually shouldn't be a problem with either RCA or TRS, although the former seems to work better if the cable has a lower resistance.
