This site is selling actual MiG helmets.

For $149.98 you get:

Genuine MiG pilot helmet worn by the Soviet Air Force. These authentic helmets -- they are not reproductions -- are new (old stock) from Soviet air force stores of the 70’s and 80’s. They come with Cyrillic instructions, are genuine leather and are equipped with the original throat microphone apparatus. If you are brave enough to wear one of these on a plane yourself, they reduce ambient noise by 25 decibels. You can't plug your MP3 player into them, but you are sure to get noticed!
