Hi All,


This is sort of a roundabout question.


At work, I use transmitter-receiver equipment so I can be heard in a 
noisy environment. My transmitter is about the size of a Victor Stream. 
I carry it in a fanny pack and connect a lapel microphone to it. The 
receiver is also about the size of a Victor Stream. I connect a headset 
to it and hand it to the party or defendant of a legal proceeding.


The other day I had a minor panic because I thought the microphone 
wasn't working. After some troubleshooting, I realized I just needed to 
put new batteries in, but I went ahead and ordered a couple of 
replacement microphones. The microphone I bought from Amazon was 
supposed to be suitable for smart phones and computers. It had great 
customer reviews and was described as a professional grade mic. The 
connector is 3.5 mm, which is what my transmitter has. The microphone 
also came with a PC adapter (same sized jack),, which is what you're 
supposed to plug in when using a computer.


My first surprise was reading about the adapter. I just assumed that 
microphones were like headsets: if you can plug it in to the 3.5 mm 
jack, it should just work.


My second surprise came when I received the mic. It didn't work with my 
transmitter, with or without the adapter. I bought three units and 
tested all of them, so the problem is unlikely to be a product defect.


On a day when I'm feeling patient and techy, my plan is to test the 
microphones on my desktop, laptop, and smart phone to find out if they work.


My question is "What should one look for in a microphone?" How will I 
know that X microphone will probably work with my transmitter or my 
laptop? I think I'm referring to the technical specifications that are 
more helpful than the ad copy.


In case it helps, the Amazon page for the microphone is here:

Thanks for any wisdom.


Ciao
