That's what I'm saying... I understand that a lot of people are upset at the lack of a headphone jack. I'm actually working with a friend to see if there's any noticeable difference using the Beats lightning-aux jack over the bluetooth (my B&O headphones sound better over cable, unsurprisingly). The lack of an aux cable makes me think Apple has really poured effort into making that Bluetooth connection the absolute best it can be in terms of audio compression and quality.
But people need to understand that these headphones are designed specifically for users of Apple's ecosystem. Which... let's see... has designed four of it's major mobile product categories without aux ports (the majority of iPads and iPhones, along with all Apple Watches and effectively Apple TVs).
These headphones being built without an aux cord makes sense because they're designed to be used within that ecosystem and to take advantage of specific AirPod technology (near-seamless device switching). So what incentive does Apple have to include an aux jack?
If you're a user that wishes to utilize an aux cable, then a.) you probably already have that Beats aux cable or lighting adapter and b.) if not, then there's a Beats aux cable for you.
