Thanks to Courtney for starting this poll! We've contacted the vendor on your behalf and they've made the AKG K712 Pro Audiophile Headphones available.
It genuinely frustrates me that so many people vote for the M50x.
A really solid, $10 hack can be done in under 10 minutes to the M50's to get a removable headphone jack. and it means your not stuck with some shitty proprietary connector.
I wish the people capable of basic DIY would know of this :/
