What sort of microphones are compatible with DUDU7 unit? I am tired of cheap microphones, people I am on the phone with always complain about my quality and I must yell for them to hear me. At the same time they complain of an echo, hearing themselves back.
Currently mic is mounted on the steering column.
Are either of these compatible?
