Hello everyone. For the longest time I thought this wasn't possible to use Google Now with your headphone. But apparently it is with the right apps. I got this to work on my Galaxy Note 2 and man, when you go out and use this thing for the first time, you'll know what you've been missing.

Basically you need 2 apps. One is paid if you like the free Trial ($3), and the other one is free. I recommend you don't mess with the single and double clicks. But program it in to the triple and quaduple clicks for Google Now and Lock respectively.

Headset Button Controller Trial (Free Trial, $3 if you want the paid version):


Screen Off and Lock (Free):

Disable the annoying sound it makes for everything except the quadruple because you want the quadruple click. Some of you with a Samsung Flip cover type cases maybe would find the locking unnecessary. A few things to note. Sometimes it doesn't activate the mic (you'll hear it when it fails to trigger). Maybe 1 out of 10 times. Just do the triple click again and it works no problem. Also it actually doesn't unlock your screen. So the problem you'll run into is that the home button hold won't respond to bring the recent apps list. But all you need to do is hit the home button and it unlocks, this is only necessary if for some reason, you hit the triple click to access google now, and you want to continue using the phone with touch. Which won't usually be the case.
