Installation in my Schuberth C3 just went, then the same time with the phone coupled (iPhone 4) and the phone and listened to music. (Complete installation material available)
Operation is surprisingly easy for a headset (best I had ever).
Before the set went with on motorcycle tour, I even made a firmware update (good manufacturing side).
On the tour went pairing with acquaintances who had a previous model, without problems.
Thanks to the "dial" and the acoustic feedback, you could use the headset with good gloves.
The acoustics were ok and switch between communication and music (for the boring motorways) went smoothly.
Conclusion - can really recommend
