Using MyPhones' Inserts
Due to the iPhone’s recessed headphone jack, MyPhones will not plug all the way into an original iPhone. You’ll need an adapter, like the Griffin SmartTalk.
The headphone opening on the Apple Bumper is only large enough to accommodate the headphones that were included with the iPhone 4. Though it appears that our TuneBuds and TuneBuds Mobile also fit in this opening just fine, the Bumper case will have to be removed before using most other headphones and auxiliary cables.
