"As the owner of a North American T-6 WWII trainer with a big radial up front I always had a hard time understanding tower or my back seater. I tried new intercom and radios tuned to perfection and still couldn't hear well. Tried all kinds of different headsets active and passive.
I was at Reno air race where Zulu had a demo booth and tried a set of Zulus. Said I'd give them a try with my T-6.
The Zulu is by far the best head set I've ever used. They solved my all noise and hearing problems with my warbird."
Zulu. Change your mind.
