i have an aux cable with a thick plastic 3.5 mm male plug on it.

It does not fit into my phone without taking the case off

I need a 3.5 mm plug / adapter / short extension that is the same width as the standard ipod headphone 3.5 mm male plug and has a female 3.5 mm connection on the other end to connect to the aux cable

Anyone know where i can get one?
