Hi Kevin,

The headsets aren't shown on the website, but they're Peltor headsets that are modified by Starcom1 for their units. They're "over ear" style and look like the headsets you see in the F1 pit lane and are pretty comfortable, although it is nice to take them off for a while after really long periods e.g. driving down to Le Mans.
However, the difference they make while driving far outweighs any minor comfort issues.
The noise cancelling is part of the Starcom1 Digital unit.
I also have the Bluetooth module and the noise suppression unit because my MSD ignition was causing a buzz. I can even listen to and reply to text messages just by speaking.
The sound quality is very good even at speed. I can talk on the phone, hands free of course, and the other person isn't even aware I'm driving, let alone in the Cobra with no roof.
