Hi. I am looking for any advice on purchasing a very small microphone. It will be used to record employees in the workplace for various reasons. Ideally, it would feed wireless to a computer on the other side of the office that will record it, as a standalone recorder would not run long enough. And it would be sensitive enough to hear a soft conversation, not nec. whispering, at maybe 10-15’ through some obstructions (over or around a low cubicle wall?). Doing a quick search got me some hits for pen-mics, handheld voice recorders and such, but most either with cords, or too big.
Any help appreciated. Thanks.
