I bought a pair of Lightspeed 15XL, sooooooo comfy and the ANR works extremely well! (I fly Cessna 152 or 172). I got em flor a little over $300 at flightstore.com ??? maybe wrong web site. But REALLY good headsets. My instructor complains about his David Clarks hurting after a while.
I believe it was Flight magazine that did an article on LightSpeeds, all raves!
