I bought these to use for a variety of purposes, but mostly for speech. My wife is the one who primarily uses these and she is not a techie. I wanted microphones with clear signal that were very easy to set up and use. These have been exactly that. We travel with these and never know what the environment will be like. We have never had problems with poor signal or interference in the year we have had them. The lavaliers are a little delicate and we treat them as such so have never had any issues. If your treat your equipment with care it will serve you well.
