Apple intros new USB-C accessories to support 2018 iPad Pros
Reflecting the switch to USB-C on its new iPad Pros, Apple has released a pair of USB-C adapters to ensure people can keep using key features.

The USB-C to SD adapter.
The USB-C to 3.5mm adapter will let people connect headphones, speakers or other accessories that depend on a 3.5mm plug. The product reflects the removal of a headphone jack on 2018 Pros.
Also available is a USB-C to SD card reader, which Apple says can operate at UHS-II speeds when a compatible card is inserted. It also supports any standard-sized SD card.
Notably, while the SD adapter will work with Macs as well as 2018 Pros, the 3.5mm adapter only explicitly supports iPads.

The 3.5mm adapter.
Both products can be shipped as soon as Nov. 1, and should be in stores Nov. 2. The 3.5mm adapter is $9 and the SD accessory is $39.

Not what musicians and pro audio folks would prefer. Just more dongles to hang off an otherwise excellent portable solution. Looks like audio professionals and musicians will choose the new MBA instead.
Guess this means no way to use existing Lightning devices with the new iPad?
Just hoping the iphone follows.
The problem I have with it is that the design isn't very good. They put the tongue inside the port, instead of on the cable, like it is with Lightning. I think the tongue should be where it's cheaper to fix/replace if it gets damaged.
Form wins over function again. Freaking designers running amok...
Also I noticed that new MacBook Air has a headphone port, and it has 2 usb c ports so you can charge it without losing that audio plug. mac_128 said: I know you can't use lightning headphones on USB C(which means people buying them can no longer use them on iPads). You can plug the usb c headphones into the usb c to lightning adapter and it should most likely work since the iPhone by EU law must work with USB C devices.
The Pro model lacking features that the basic model having is a new trend with Apple for some reason, the XR having a bigger screen with better battery to XS, the Pro model that you pay $150 more than the .5" smaller not having a headphone jack, the MacBook Air now having 2 Thunderbolt 3 ports, better battery life, and a larger screen over the $100 more MacBook are all examples why Apple has made some of its weirdest and most confusing(not to mention massive price jumps) product lines this year.
I'm pretty sure Apple refuses to allow its accessories to work with Android/ Windows so they will never release a lightning to USB C adapter (unlike what they did with the 30pin to lightning), while neglecting the fact that that made IOS accessories incompatible with Mac, and now just iPhone accessories incompatible with any other Apple devices(excluding the accessories of the newer Magic Mouse, keyboard and Apple TV remote still being lightning, which the Mac accessories suddenly make even less sense).
Also, why did they not have this USB C to SD card reader before so MacBook users could have used it for the past couple of years?
