An EV-enhancing item, when held, increases the number of EVs gained when a Pokémon is defeated. They all halve the Speed of the Pokémon holding them.
If a Pokémon holds an EV-enhancing item (except for Macho Brace) while in the Day Care, it will pass its IV in that item's respective stat down to its offspring.
