Installation was really quite easy, size of the unit was just a bit larger then the Cardo system I had, but not too much larger. There were a could differences that were immediately noticed. The Cardo system had a Vox capability, the intercom was off until you started talking and would then kick in. Since the Cardo was an older system, it did not allow music to pay from my iPhone. The Lexin unit has a button you press to activate the intercom between the two (or four) headset systems. Iphone is available for music or phone calls.
Noise cancellation on the unit is really good..no wind noise at all! So far have not tried multiple headset connectivity. Will report more as we get more mileage with the head set!
