I suspect the answer to this question is a straight up "No".  But I am going to ask it anyways....
I have a DDRC-88A which I use in my studio, between the mixing desk and the powered monitors, which have their own amps.  The mixing desk is fed with audio from a 32-channel sound card, and sums that to two channels.  I use the DDRC-88A for room correction.  It's great because it is low latency, and doesn't affect my ability to play and record instruments into the computer system, which has a latency of around 12ms.  
I cannot add isolation or do anything to reduce the impact of the noise, and so I'd like to try using noise cancelling bluetooth headphones some of the time, in order to deal with it.  As I understand it, consumer grade bluetooth transmitters have relatively high latency - even the ones which use the aptX low latency protocol will add a delay of over 40ms.  I don't know what extra delay the noise cancelling of headphones adds, but there are some new Korg cans which are aimed at DJs and therefore probably have lower latency than consumer grade headphones. 
I realise there are no digital outputs on the DDRC-88A.  But is there a way of routing audio from Dirac in the PC to a bluetooth transmitter that won't add lots more latency?  Is there a different Minidsp product that might do what I want?

At least some NC phones have wired connectivity.
Not sure about delay due to the NC, interesting question.
