Q: Sony MDR-ZX770DC or MDR-ZX770BN and AptX (Apt-X) bluetooth and OS X

We just purchased a Sony MDR-ZX770DC and Sony MDR-ZX770BN BlueTooth / noise-canceling headsets.   (Note: the difference between DC and BN models seems to be about $100 and not much else).

 

These models support the AptX codec, but by default seem to choose the SBC codec.

You may need to quit the app, un-pair, then re-pair your headphones.

 

At some point, in both 10.10 and 10.11, it works!

Mac mini, OS X Server, OSX 10.10.5 with Server.app 4.1.5
