I want to do weekends away with my wife, who has zero interest in things four-wheeled; and I'm on the verge of a tinnitus issue (British sports cars and motorbikes), that I want to avoid!
It's not a cheap solution, but for motorway driving we have adopted this solution which some Caterham drivers use: a pair of ear defenders with boom microphones and wireless interconnection.
It deadens the sound (we drive with the roof off most of the time) and we can chat, answer phone calls, and listen to shared music. Not the most comfortable (especially if sunglasses press into your skull) but it is transformational for the noisiest parts of the journey. Other options are available including one designed by a Caterham specialist.
