Could be working on Headphones which have Stereo Microphone ... But I've never heard about Stereo Microphone Headsets before ...
This might only change if Sonys Technology gets copied by other Vendors ... Would be great, cause it makes this technology open to the masses and much cheaper, while you can still choose to use the same headphones without NC.
