I use moulded ear plugs all the time, one thing they can't transplant is your hearing. All ear protection feel's odd at first but so do most new things.
The once i use can be washed after they have been used, your body heat warms them to adapt to the shape of your ear canal, come with a detachable cord and a small storage case to keep them in. Cost of them......£0.98p per pair...YES only £0.98p per pair....!!!!!!!!! Now i am sure all of us can afford that. Not a lot of cost to protect your hearing.
