It's almost a given that the Bose Headset X is at or near the top of every pilot's wish list, in large part because the $1000 noise-canceler is comfortable, quiet and sleek. Now comes the LightSPEED Zulu, a clear shot across the Bose bow. So here's the question: Can the $850 Zulu's performance earn it best-in-class status?Although LightSPEED claims that the Zulu is the quietest headset on the market, there's more to beating the Bose than just noise reduction. Along with quietness, we also weighed comfort, audio fidelity and the headset's feature complement.This was a subjective pilot test, conducted in two different cockpits: a pressurized Lancair IV and a two-year-old Columbia 400. The Columbia had a jack setup, combining Bose's unique single connection and the two-plug industry standard in the same jack, so we could have two headsets connected at the same time, swapping them in seconds. It was as close as you could get to back-to-back using one pair of ears.
