Binaural microphones for iphone?

Hello,

I was wondering if there are Binaural microphones for the iphone. I know there are Binaural earbuds like the Roland CS-10EM. They can be used as normal earbuds but there are two mics build in. When you play the result of the recording it sounds very realistic. There is a way by connecting the Roland CS-10EM with your iphone but you need an external power device like a Tascam. Someone made a review of this combination:

But I read a few months ago that apple made it possible to use power over the lightning connecter for external devices like active noise cancelling headphones.
Are there already binaural microphones with this option on the market?

Thanks
Regards
