what's the best bluetooth for iphone 5

With my iPhone 4 I used to love my Plantronics Voyager but didn't fit well in a smaller ear. Then went to the Blueant Q2 and not as good sound quality but the fit was better. Now I have the iPhone 5 and the Blueant doesn't cut it in general and with Siri also has answered my phone twice without picking up.

What's a better option?
