I have a SENA 3S Plus Boom Microphone Kit installed in an HJC C91 modular helmet.Just curious, what SENA system are you using? Was not aware of any that did not have external controls or am I reading this wrong?

The 3S Plus is two earpieces connected by a cable. The cable runs around the back of the helmet. There's also a charging cable, which is the one with the squarish end on it.
The "boom" part is a microphone that extends from one of the earpieces in front of your mouth.
The on, off, and volume controls are the buttons you can see on the microphone.
With the helmet closed I can't get to the controls, so after turning it on I have to remember to increase the volume before closing the helmet.
