Flying a 172 and using low end David Clark headsets and ending up with a splitting headache after about an hour I decided to buy my own headset. All my Instructors have DC’s but I used a Lightspeed when I demoed a SR20 and loved the comfort and sound quality. I called Lightspeed with the intent of buying their “25” model, but when I told the rep I was interested in buying a SR20 he recommened their own SR20 Headset which is supposidly tuned to the noise inside the Cirrus SR20. So for about 500$ I am very happy the ANR works great and they are very comfortable. My CFIs are even starting to see the LIGHT.
