I just wanted to jump in because this thread was making my head hurt. From what I've read, it appears Timmayy is defending Apple's decision and that the removal is a step forward.
Ok, I get removing DAC can contribute to better sound quality, but if you think Apple cares about sound quality; help me understand why they provide you with the biggest POS headphones with their products. I'm sure the lightning headphones will not provide any better quality than previous models with 3.5mm headphone jack. Too soon to tell on the Airbuds or whatever they're called, but I can take a wild guess at how the quality will be.
I'm also seeing a lot of people comparing this move to killing off floppies - which is ridiculous on many levels. The successor to floppy disks was already present and reliable. Floppies were expensive and inefficient. What Apple is doing is killing off a current and ubiquitous technology in favor of a more expensive, complicated, less-efficient and less-reliable technology. In the case of the 3.5mm headphone jack, they have not replaced it at all, they just took it away. It was neither aging, in process of aging, nor hurting at all. This is all done to upsell some **** quality BT branded headphones. They're right, this does take courage.
I've already decided not to "upgrade" the iPhone 7, instead will get a 6S with more storage space. I just had to rant in response to this rant.
