When you connect "Nintendo Switch Famicom Controller" to switch, The icon on screen also appears as Famicom Controller.
also, 2P controller has Mic on it and It can be use on some of classic Famicom Games(NES controller doesn't have Mic)
It will be nice if we can use this function by Smartphone Mic.
