In my review of the Cleer Flow II headphones I suggested that the designers of the Muse might consider using the USB C charging cable for both power and audio, thus reducing the number of leads:
" Mad thought: Cleer boasts that users wanting to enjoy the highest frequency response or make use of a better DAC can do so via a cable connection. Both of these functions could in theory be served simultaneously via the USB C connector, in which case the headphones would also be able to keep themselves fully charged. Why would anyone want to run two cables to the headphones to use them, or feel obliged to charge them when not using them, if all the tasks could be achieved simultaneously via one cable? I’m not sure of the electrical/ engineering requirements but this may be worth considering as USB C outputs become more common."

I’ve just had an email through from Centrance, makers of the excellent Dacport DACs, saying that their next product (the Hifi M8 V2 Dac/Amp) will have this facility:
“Looking at the back panel, the left hand side USB C jack can be used to both charge the battery and play USB audio.”
I really do think this is worth thinking about from the point of view of how things will be in the future as opposed to how things have been done so far.
