Is the quality of recording or audo lessened with a wireless headset?

Question

I teach english as a foreign language in Vietnam. I need a microphone that records voice clearly such that with amplifications and other adjustments it still sounds normal and clear.

Answer 1

I can't give you a direct reply but I can tell you that I found different microphones gave different results (so I assume wireless is the same). Go to your local computer / kareoke supplier and ask to test their wireless headsets - they should be able to set it up for you, and find one that works.
