The Scala Rider Teamset or Q2 multiset seem to be very good, and voice activated... I'm in the same boat... looking.
They make a set for just you and your passenger, or bike to bike communication with other riders.
Scala now has the Q4, which is even more advanced, along with stereo output for music, if that's important to you, but also pricier.
Scala is probably the favored and most popular, but there are others, such BlueAnt, and Chatterbox. Others will chime in with their experience, but I think those are the major players.
