I have sensitive ears and am on a serious budget. What works for me is any noise cancelling headphones with over-the-ear hearing protection. I got some electric ones from Harbor Freight for under 15.00, and I can just turn the volume up on them to hear people without having to remove them. Works great around the house, but might get some looks out in public.
