I can't sleep without them. I did quite a bit of experimenting, and I like the CVS brand soft foam ones the best, 30 decibels. They're Celeste colored (like a Bianchi).

I have a nearly full pack of Mack's Ultra safe Sound (32 decibels) you can have for free. The best thing about them is the pack has instructions on placing them properly in the ear. Seems simple enough, but the technique on their bag makes a big difference. These were a little uncomfortable for me, but you might like them. PM me your address if you want to give them a shot.
