Review on ✈️ CRAZEDpilot CP-1ANR: Ultimate Active Noise Reduction Headset for Aircraft by John Goerge

Used twice in 2 hour flights - mic stopped working after 60 and 80 minutes respectively. The replacement of the headset worked correctly. The device was delivered without an information booklet and it was only after visiting the website that I realized that ANR only works when connected to an aircraft. The device is heavier than some ANRs and looks cheaper than many other systems. You get what you pay for! I returned the device for a refund. It's not good to see that you can't talk to Approach in class B airspace!
