I also suffer the cabin pressure / tailgait boom problem - although the service centre here has been very responsive to try and resolve. I similarly can't imagine living with the car that has this problem, my wife isn't bothered by it but it gives me a headache. It went back to be adjusted which helped a bit but not completely, it's going back again in a couple of weeks for a more comprehensive attempt. If you google 'Tesla S pressure buffeting' you'll find various things. I'll let you know how I get on. It varies from car to car, apparently.
