Hi Steve, I've got a pair of Sena SMH10s and love 'em to bits. They are extremely simple to use (even with heavy winter gloves), and the audio quality is outstanding. The signal processor in the microphone works so well that most people don't even know I'm on the bike when I'm talking to them. If the visor (full face helmet) is fully open on the freeway, then it sounds like I'm in the wind, but the conversation is still quite reasonable.
They also have several different mounting options, but the one it comes with is the one you'll need with a flip-up - the mic is on a boom that can be positioned just right. The same mount (I think all of them actually) also has an AUX input so if your player doesn't support Bluetooth, then it will still work.
The current firmware also allows each headset to pair with their own music player, and to allow music to be played from one headset/phone through the intercom to the other.
They aren't cheap, but the good ones aren't. You can get cheaper versions on eBay, but their quality if poor, too many buttons, etc.
I had to play a little with the fitting - a bit of foam under the speaker to bring it close to the ear made a huge improvement in the audio quality: the Shoei TZX has a recess for such speakers, but it was just too deep. Be prepared to experiment a little - regardless of the system you end up with.
For me - 11/10 for the Sena - hard to go wrong.
