The ones I have are not marked EMG (the better Deans have real EMG I think). These are probably generic copies of EMG for all I know. They came in one of those newer Dean Edge active basses (made in China). Due to a (probable) fried preamp I've never really got to try the pickups, however, I have tested them and they do work, I just couldn't play the bass through an amp due to a jacked up preamp. So, are the pickups worth keeping and using in some future project? Or are they generally not that great? Will they work OK as passive pickups, or do they need that preamp to sound their best?
