So I have been away from here for a while, but I see that there is now the Axon 9, and 10 and they both have standard 24bit DACs and no headphone jacks. The 32 bit DAC that the axon 7 had much clearer audio quality than the standard Qualcom DAC (nothing to do with the bits, just the quality of the hardware).
I just wanted to let ZTE know that this is a deal breaker. ZTE captured part of the audio enthusiast market with audio hardware that was superior to all but one or two phones in the 7th generation. I bought the Axon 7 specifically for this.
Going away from this feature, along with loosing the headphone jack means that I will probably get an LG V series phone when my Axon 7 dies.
