3. Can the E18 connect digitally to iPhones?
A: Upon our testing, we found that iPhone4 and later models may connect to the E18 via Apple's official Camera Connection Kit (CCK) (which provides a standard USB port for the E18 to connect to) when the phone runs iOS 7 or above. Note that the iPhone 4 required the 30-pin CCK while iPhone 5 and later require the new lightning port CCK. While our test results show these to be the working conditions (iPhone 4 or above, iOS 7 or above, official CCK), FiiO makes no guarantee that the E18 works with all such units.
