Yes indeed, I found it now. I read into the thread but not too carefully so I didn't see post #239 by Redcarmoose which links the initial article to this rumor.
This out 16 hours ago. New mfi specs!
The Lightning headphones will be capable of receiving lossless stereo 48 kHz digital audio output from Apple devices and sending mono 48 kHz digital audio input. The input means that the headphones will also support a microphone for audio input following Apple’s upcoming update. Manufacturers will be able to take advantage of Apple Headphone Remote controls like Volume Up/Down/etc, as well as other buttons for launching specific apps such as iTunes Radio or initiating playback controls on iOS. In addition, the headphones can be made to work specifically with a companion iOS app and launch a specific app when connected to an iOS device.
I thought it might be worth to be a separate thread but I can close the thread if it is not relevant. Just PM me.
I think it is super disturbing to see Apple forcing users into using separate DAC with their product instead of
integrating a proper one. Especially in the MacBooks which are pretty expensive: I have an old and a quite new MacBook
and in the new one the headphone jack is unusable because of an extremely loud humming coming from the poweradapter.
If Apple was about improving their sound quality they hadn't have bought Beats but 3 different companies (headphones,
DAC company, streaming service) as has been discussed before. Now it kind of makes sense to me because if you want
to force the average Apple customer into buying a certain headphone brand Beats is probably the easiest way ...
Other companies will have to increase the prices to their products in order to integrate DACs and licensing fees. Another
disturbing fact is that they have to present their product prior to release to their competitor in order to get licensing.
