Hi 66yr old and wife, venturing on an ebikes first time still looking for bikes but also researching other equipment. I would like to know if you can get a lightweight headset that fits inside or close fitting inside the helmet like a two way walkie talkie . To be able to speak to each other rather than shouting and drawing unwanted attention. Preferably not connected to mobile phones Bluetooth or the like. Just simple easy to use radios ? I have googled it to death. Can't find what am looking for. Any help greatly appreciated.

This thread discusses possibilities, but this post from NigelBB looks a really nice option:

Try a tandem. Some love it, some hate it. Still can't talk in heavy traffic though.
