Tried plugging in the ear buds and no sound coming out while using phone or listening to Youtube. Also can't find any settings that need to be turned on for headphones, so what gives? I know others are using them, so how'd you get them to work? Update: Another Epic has to go BACK!!!!!! Contacted Sprint technical support and the ear bud should work by simply plugging it in. This will be my fourth. Final update: Well this is embarrassing. Went storming into the Sprint store to return my phone, and the guy behind the counter wanted to check it out first. I knew I had screwed up, when he forced the headphone jack ALL the way in. I had pushed it in and applied as much force as I felt comfortable with, but it wast enough, the jack needs to be fully plugged in. Duh!
