Bose A20 Aviation Headset 4 Year Review

I just purchased my 2nd A20 headset so I decided it was time for a good review after 4 years. In my opinion this headset is worthy every penny. Ive used others during the years, Farro, Bose X, Av-comm, David Clark. To me, nothing compares to these. I purchased the 2nd headset from Sportys for pretty much $1100....$1, is the actual price. The same I paid for this one 4 years ago. Sorry for the breathing, didn’t have my professional mic hooked up and this time of year my Asthma gets me in this cool, dry weather.
