ANR Retrofit: Making an Old Friend Better

AVweb's publisher recently retrofitted his old David Clark headset with a $169.00 active noise reduction (ANR) kit from Headsets, Inc., and then test-flew the modified headset in three different piston aircraft. He found installation straightforward for anyone not intimidated by a soldering iron. How'd the DC headset perform after the ANR retrofit? It won't match the comfort or sound quality of a Bose or LightSPEED, but there was a huge improvement in low-frequency noise attenuation. Final verdict: the mod kit is definitely worth the cost.
