Oh yeah, forgot to mention that any place that sells hearing aids should be able to sell these, or a similar model of whatever brand they sell. They actually fill your ears with an expanding 2 part foam, let it harden, pull it out and send it to the company to mold it to fit your ears. I think it took 10 or so days to get them back. They fit great, but when I get a bad head cold in the winter, they are a little tight with the sinus swelling. I can hear a whisper in a quiet room, but they filter out the loud noises. In the past, if I wore regular foam plugs, I would pull them out to talk to people normally, but not get them back in. In my job I am in and out of extremely noisy environments all day. Whatever hearing protection I have doesnt' help if I don't wear it. These are comfortable enough, and allow for normal conversation, that allows me to wear them all day.
