Though I haven't had a chance to fly with one yet, I did have a chance to check one out a few weeks ago before the product announcement. It's a really cool headset and certainly a worthy contender against the Bose A20 / Lightspeed Zulu. I think you would be very happy with one. If you're out at AirVenture in a few weeks, PilotMall.com (my company) will have them on display in Hangar B and Hangar C. As well, we have a 30 day return policy if you want to pick one up and take it flying...
