  • Your Sound, Your Stage, Your Way to Hear It Better!

    Adding wireless in-ear monitoring to your setup is remarkably simple. Samson EarAmp sends audio signals wirelessly to in-ear monitors worn by the performer. This eliminates the need for cumbersome floor monitors that are a pain to transport and manage in live sound situations. With EarAmp, performers can hear themselves and their bandmates clearly and in real time, giving them more control and improving their performance.
