Llegó en el plazo previsto, bien empaquetado en fundas antiestaticas y funcionan correctamente. Lo unico que faltó fue una mejor explicacion de las características del producto. En internet hay mejores explicaciones de como funciona el pin KEY y filtros para el ruido que puede entrar desde la VCC. La calidad del sonido es muy buena y cumple las expectativas. Para el que no quiera usar el pin KEY, recomiendo que al encender el MH-M18 por primera vez se puentee con una resistencia de 33k el pin KEY con GND durante unos segundos hasta que se escuche el indicador de maximo volumen, de esta manera la señal de salida será la maxima cada vez que se encienda, ya que tiene memoria de volumen y no será necesario volver a puentearlo si se apaga el dispositivo, si no se hace esto la señal de salida sera muy baja y el aparato receptor se escuchará muy bajo.
