shielded condenser mics

[Robert Adams]

I am experimenting with modifying the audio channel of a cell-phone,
and one problem I have is that most cheap condenser mics these days
have plastic housings, and I get a lot of RF interference from the
cell-phone itself getting into the audio. So I am looking for a tie-
clip style mic that actually has a metal housing. Also, it should
preferably NOT include a battery, as I am set up for phantom power.


Any suggestions?

What are you using, some big computer type mic, like a Mr. Microphone ?

Where are you looking.

It might be that extra length wires is going to screw you up and have less to do with microphone case design.

No, I am using one of those mics that ships with a typical PC. You can
buy them at radio shack. The pickup is coming from the mic itself, not
the wires.

I'm not sure I'd be so quick to blame the mic. After all the cheap
ones seem to work fine on cell phones equiped for a headset.

The standard cell phone ear mics seem to work work ??
I have used a couple over the years.
