Second generation four-dimensional recitation ear return
Real time ear feedback monitoring, synchronized listening and reading, and more rhythmic endorsement
Research has shown that synchronizing "speaking" and "listening" can help stimulate brain memory and improve memory efficiency. The external microphone picks up the original sound in high definition, and after technical optimization, amplifies the original sound and transmits it back to the ear in real time, making echo memory and memorization easier.
