Voice search with Google Now using the button on Bluetooth headset on GS4?

[krauster]

When I have a bluetooth headset on, and I'm not doing a phone call, it would be nice to initiate a Google Now search by touching the bluetooth headset, saying Okay Google, and have it do a search. Is this possible?

Although most of the search results I get from google now don't respond with audio so it might not save me from having to get my phone out of my pocket to look for the results.

Pressing the mic button activates S-Voice by default. As far as I know you can't change that to GNow :-\
