UPDATE: I feel like an idiot...please disregard this post. My headphones aren't working with anything atm ):

recently got an iPhone 4, and the headphones that came with it are working but my other personal ones are not.

I don't remember hearing anywhere that it doesn't recognize any other headphone types like the original iPhone...right?

Tried the stuff on this website but nothing is changing. Anyone know what's up?

I only have one extra set of headphones laying around so I can't test it using other types, but the ones that I was trying to use are JVC Super Bass HA-X570.

Thanks in advance for any advice!!
