Question about Sena 50S - Sound by Harman Kardon

Yes, that is partially possible. I have already been able to pair mine with different Cardo devices. But it always depends on the device, MESH, Bluetooth standard and above all the installed software... Cardo has just recently released an update with which most devices (with Bluetooth 5.2) can now be connected to the Sena.

I don't know, I have never tried this before. Sorry
