Buenas tardes: Uno de los intercomu

Buenas tardes:
Uno de los intercomunicadores no se escucha bien, a veces se sube y baja el volumen solo, otras veces no dura la batería (como si no hubiera cargado bien) y al ponerlo en carga se hunde la clavija donde se conecta el cargador. Cuando está en el casco puesto, si muevo el cable se deja de escuchar o se oye un ruido de fondo.

結果 (英文) 1:

Good afternoon: One of the intercoms can be heard well, sometimes is up and down the single volume, other times not battery life (as if you had not uploaded well) and put it on charge the plug where the charger connects sinks. While wearing the helmet, if I move the cable stops listening or a background noise is heard.
