So awhile back I was working at Best Buy when someone comes to me asking about headphones for DS lites, upon talking to him he said he didn't relize that headphones were essentially required to hear the DS lite's sound, immediatly I suspect something is wrong with his DS lite, but a coworker confirmed to me that his system was also like that. Is this something Nintendo changed from the normal DS to the DS lite? This is something that would keep me from upgrading if true, however I also remember when I first got my DS phat that the volume was turned all the way up, and it took me forever to relise that there was even a volume control, so I'm wondering if Nintendo just did the opposite and these two people were confused about the situation.
