I'm also most hyper-sensitive to sound. Smell, sight and touch I'm also oversensitive to as well but much less than sound. I own six pair of what you see below in various colors and configurations (e.g. a few models have speakers for stereo most are just hearing protectors. I keep two pair at work at my desk when I need to focus and filter out all background noises, one pair in the vehicle and the others at home. I wear them around the house when my family is loud, working outside, etc.
When I'm out in public I wear foam earplugs. Not all the time, but often. When I'm stressed, my hearing sensitivity seems to be greatly elevated.
I'm afraid I can't be any more help, but I very much like my over the ear hearing protectors.
