"As part of the 3 person flight crew, flying a DC-6 all over the state of Alaska, I have had the opportunity to try multiple headsets owned by the other crew members. Without a doubt, hands down, the quietest, most comfortable headset that I have had the opportunity to try on, is the Lightspeed Zulu.
I have owned a couple of Lightspeed headsets now for several years and have been very impressed with the customer support and service that Lightspeed provides. That, coupled with what I consider to be the best aviation headset that I've ever put on my head, has got to make the Zulu the best ever."
Zulu. Change your mind.
