Okay, folks. There are guys out there already selling iPhone headphone “adapters” that let you plug “regular” headphones into the iPhone’s super-recessed headphone jack.
Don’t waste your money. You can use regular headphones with the iPhone, easy. All you need is a sharp knife.
Take that sharp knife, take a pair of headphones, and right around the headphone jack, trim off about an 1/8th of an inch of the rubber around the jack. Then plug your headphones into the iPhone. Click, they can now fit in the super-recessed iPhone jack.
I’m using a medium-priced pair of “normal” headphones that I just altered this way right now, and the music is coming through perfectly.
And yes, you’ll still be able to use the modified jack on everything else.
