I give you 10 out of 10. I bought two headsets in two separate orders, and both arrived promptly. The headsets are great. We have had some trouble in our aircraft with interactions between headsets and the radio, but yours were trouble free. They seem good at damping external noise, and the headphones are very clear. I was originally going to buy your more expensive set but they were out of stock, so I decided to buy the cheaper pair and try them out. As a result I was able to decide that the cheap pair were fine, and bought the second set. As for other makes, not sure why anyone would pay £500 for a headset.
