I know that John Chatterton and others do use an MP-3 player during deco. I dont know what kind they use or what housing.
I have also heard from Bret Gilliam and several others that would take old books to read. The pages do get damaged.
I have only done relatively short deco stops; I am not sure how I would deal with a long deco stop. I think that I prefer to avoid them.
