I have been flying around with a passive headset for years and finally made the jump to the ANR headset world. I am currently flying Learjets and was leaning towards an over the ear model and stumbled across this headset days after it came out. The only review available was done in conjunction with AOPA magazine. I watched their video and was impressed. However, after using the headset for two months I feel like maybe I should have gone for the Lightspeed or Bose headsets I originally had my eyes on.
I used the headset in a King Air C90 first. It worked well in that platform and after swapping with the Co-pilot seemed to block out as much noise as the Lightspeed Zulus. However, I have not enjoyed my experience with them as much in the jets. Our jets don't have much insulation and tend to be a bit noisier than average and I feel like I am having to turn the volume up due to wind noise in the background. I have also used the headset in a twin engine piston and found the noise reduction levels to be good. but overall the exterior noise level seemed a bit high.
In addition, I tested the music feature using Bluetooth and while the setup was easy I found that the fade in after the auto cutoff for comms is a little long but acceptable. Otherwise works great on droning level flights.
As for comfort, I find that my ear starts to hurt after about 3 hours of flight time and I end up constantly readjusting the headset. I have tried multiple configurations but I have yet to find a sweet spot. Still hopeful in this regard but I think the clamping pressure is just a bit too much with little reward in passive noise reduction. However, I would say that the discomfort is less that the average over the ear headset especially when wearing sunglasses.
David clark emphasized passive noise reduction in their informational video but I found it to be minimal.
Battery life seems good. I have changed them once in two months and fly about 50 hours a month. The yellow and red lights can be hard to notice but are good indicators of low batteries.
Overall, I would say not a bad headset but just wasn't quite what I was looking for overall. I was on the fence about giving the headset a 4 but the discomfort on my ears for an over the ear headset is really significant to me.
