I have a Cardo Scalarider G9 and have it paired with my Zumo 660, which is paired to my phone. The Zumo has over 500 of my favorite songs in the internal MP3 player. I also have a Sirius/XM satellite radio that has a FM transmitter, so I can use the G9's FM receiver to listen to that. The G9 has voice control, so after I turn it on, I don't have to fool with any buttons. If I want music, I say "music on" and the nice lady that lives in the G9, replies "music on" and the music starts. I have the MP3 set up for random play, so it selects the songs. If I want to manually go to the next song, I say "next track" and it goes to the next song. When I want to shut the music off and listen to the sat radio, it takes 2 commands, "music off" and then "radio on". If I get a phone call, the music pauses and I say "hello" and then talk. As others have said, the noise cancelling is amazing and people on the other end of the call can't tell that I am cruising down the road on my bike. It also has auto volume control, so it compensates for ambient noise as my speed increases.
Best of all, that sexy lady in the G9 welcomes me when I power it up by saying "Hello, Fred Ziglar". and when I turn it off, she says "goodbye". Don't any of you tell my wife about that sexy lady, or I'll be in trouble (again). ;D
This fall I was blasting down the Cherohala Skyway with a few other guys, hitting triple digits in several places with Megadeth cranking in my helmet. The road was freshly paved, the leaves were changing, very little traffic, and the temperature was perfect. It was surreal. I found that the music focused me rather than being a distraction.
