TOA speech microphones are optimized with a frequency response tailored to emphasize clarity, thus delivering increased intelligibility. The WM-5225 microphone employs electret condenser elements that minimize handling-related noise, making them particularly suited for speech applications. These microphones feature a more streamlined, less bulky profile compared to conventional models, thanks to a new built-in antenna.
