Which bluetooth ear pieces will work best with My Samsung S6 Active?

[AC Question]

I recently upgraded from a Sony Xperia to the Samsung S6 Active. (I know, long overdue). I have always used a bluetooth with my phones, and have a Motorola H19txt which has worked wonderfully for playing music and for voice activated calling/texting. Now that I have the S6, the voice activated calling no longer works unless I unlock the phone and activate either google voice or svoice on the S6. My car's bluetooth (2014 Toyota Corolla) works with voice without having to touch the phone. Does anyone know what technology I need in a new earpiece or can recommend one that will work?
