Word had also been circulating that Apple was going to announce HD audio playback, new headphones, and new lightning adaptors. After WWDC, I predicted that this change would probably be aligned with the expected fall release of a new iPhone.
These new specifications allow manufacturers to create headphones that connect through the Lightning port.
iOS software does not support this yet, but a future update will support it in iOS 7.1 and later. These headphones will be able to play audio files with a sampling frequency of 48kHz.
The technology also supports mic inputs and headphone remotes. Headphones will be able to draw power from the device through the Lightning connection. They can also receive firmware updates.
There are two options for manufacturers. Standard Lightning Headphones use minimal components and Advanced Lightning Headphones allow for more features.
