. Now size does matter 
At the game fair i came across a family business that deal with personal moulded plugs. They pop a piece of foam into your ear and then fill it with a liquid material. The impression then gets sent back to their lab where they cast a nice set of ear plugs.In the bright orange that i ordered, even i shouldnt loose them
Have a look and see if they take your fancy
