Setup my new Macbook pro yesterday including my Sony MDR-ZX770BN headphones and all was good with the world. Tonight turning things on the head phones sound like they are in hands free mode. Factory resetting them as well as removing and repairing with Macbook gives same result. Pairing with my surface pro is fine as well as my iPhone but it'a like the Macbook is using the wrong profile. Is there anything I have missed here.
