Phone headset wiring

Can you pass along the T/R/S specs for the typical telephone/cellphone mini plug?

Gotta love google...all I get are wacko "OMG CELL PHONE RADIATION WILL KILL U!!!11111 BUY THIS!!!!!" pages. Tell them to visit a tower site.<P ID="signature">______________

tip and shield is the mike, tip and ring is the headphone/earpiece.

I have good luck with my flip phone (Motorola V-60 series) just wiring an XLR in tip and shield, then plugging in a 635 mike. Don't try to put a cap in line with the mike, the transformer in the 635 seems to load down the phones phantom supply nicely & convinces the phone that there is a mike plugged in. You need a 635 or similar mike with a high output. One of our guys plugged in an RE-16, unless it was close-miked it did not have enough output to kick the phone on, & he would drop out.

Easiest way to build a quick remote set-up is to find an hands-free mike/headset combo which has two pair shielded cables running from the mini-plug. Chop the condensor mike loose, split the wires apart, wire up the XLR & you're done. You should have enough free cable so that the talent can stick the earpiece in his ear & still have enough cable to do an interview.

That's the direction I'm going. We have a Shure SM58 laying around that I was going to wire in but I'm pretty sure the Z on the sm58 is like 300 and it would dislike phantom power...either way, we're not doing the "pass the cell phone around to all the guests" game anymore.

Since a station is already doing a christmas format, I suppose I'll start my christmas list:

Just a recommendation, if you are going to use the T/R/S, do not do it on a GSM phone. The audio quality is aweful. GSM Tieline, that is the way to go. Even IP would work well - At NAB, the folks from Tieline were demonstrating the IP Tieline module - audio music was crystal clear at 28k!

For about $15 bucks, (less if you have the mike connector), what doe you have to lose?

The phantom power is on the order of about a half a volt out of these things. As long as the mike has a transformer in it (as do most EV mikes, and probably the Shure, should not be a problem.

Be fun to play with & gives you a lifesaver when everything else fails.
 
Shure SM58's are impervious to phantom voltage, even at +48v. But I do think they are a little heavy for handheld use.
