Earlier quoted context omitted.

The proposal sends analog audio out on the auxiliary pins, so adapters will be passive and dirt cheap.

Presumably this also means it won't fix the issues of noise mentioned in the parent comment.

You've got analog on the aux pins and digital on the main pins. The digital isn't active unless selected, so it doesn't induce onto the analog. Best of both worlds. (except for the adapter required part).

Some type of chaining adaptor makes more sense.

And given that usb-to-3.5mm adapters already exist, I assume that if this happened, the appropriate adapter would appear on the market fairly quickly, so you could keep using your old headphones.

So now I have this ultra thin cable going to the phone in my pocket, but next it will have to be a whole USB adapter - I'm really not looking forward to that.

At the same time - sure, Intel should go ahead and implement this. But phones should just have both USB and 3.5" connectors.

If a phone only has one USB-type C connector on it, how will you both charge and listen to music with your headphones with it? Is there going to be two connectors, one at the top and one at the bottom?

A small USB type c hub, powered from the thing it's connected to. May be as small as a cable inter-connect 3 type c sockets, 1 for the phone, and one each for whatever you want to connect to. You could daisy chain these or have hubs that offer 1 in and 6 out, etc.

If I'm on an airplane listening to music/watching a movie on my device, the last thing I want is another dongle to keep track of.

I hope that nobody get's the idea of encrypting the audio data for playback. I still can remember the problems of trying to play movies over HDMI which didn't work because some device didn't support the encrypted channel.

As Anandtech points out it gets HDCP, so I'm sure there's going to be some uptake for apps that require a protected path.

If Apple does introduce a Lightning-only iPhone in the fall, I am increasingly convinced they'll include some whiz-bang EarPods to sell it as a feature. Any reason they can't miniaturize some ADC/DACs for nifty adaptation to ambient noise run on the phone?

You mean I will be able to listen to the music on my phone only using god-awful horrible-sounding hard ear-buds from Apple whose only redeeming quality is proprietary lightning connector?

Thanks, I'll pass.
