I'm about to grab the MH1C and pair it with the Note 2. Will let you know if the headset can receive/disconnect calls with the buttons.
[Edit]: I did check out the Note 2 with the MH1C and can confirm the mic + buttons works well. I first used an app called Bubble UPnP as the music player and received a call. The music softened and I was able to receive the call via the touch screen interface. When trying to use the buttons and doing a single press of the center button, the call is received - but the music continues to play and mixes with the incoming call? Double pressing the center button hangs up the call and the music continues to play. Believe this is a bug with Bubble UPnP app.
The little "back" button at the bottom of mic doesn't do anything and is practically useless.
Doing a long press of the center button, Google Now app starts-up and voice instructions/questions can be given. I asked for the local weather and it worked.
Another test was using the stock Samsung audio player and this time using the mic + buttons behaved more reasonably. When receiving a call, the music would soften and fade away. Pressing the center button would engage the call - there's no mixing of the incoming call and music (as per Bubble UPnP) and one can listen to the call as per normal. Double pressing the center button would hang up the call.
