My wife likes to wear a hat which is incompatible with headphones.
We are experimenting with an intercom system and earplugs for when driving at motorway speeds, i.e. just getting to somewhere. We have Elgin Rumble earplugs which are easy to insert and have inbuilt speakers as well as noise attenuation. The earplugs are plugged into Cardo Spirit intercoms. I have purchased some cheap behind the ear headphones that I have taken the speakers out and have attached boom mics to. The Cardos are bluetooth connected to my phone and the phone is also connected to the Morgan sound system, for streaming music and GPS audio. This setup enables us to hear the stereo, GPS directions and talk to each other. I can change the volume so that I can still hear the engine noise.
I am also experimenting with a wind blocker behind the seats. Going to use a sheet of acrylic attached to the headrest stems. The acrylic will have holes in it to attenuate the wind and therefore mitigate turbulence, rather that act as a solid barrier. Once I have the configuration sorted I will make the final version out of polycarbonate if it works.
