AViation Zulu Anr

Types of aviation headsets?

Hi, somebody could tell me what means PNR (Passive Noise reduction) ANR (Active Noise Reduction) ENC (Electronic Noise Canceling)??? what headset is more comfortable??? Many people uses David Clark, other uses lightspeed zulu or bose.
This brand is more economy: http://www.pilot-usa.com/ What do you think?

Comfort is defined by the wearer. Everyone's head and ears are different. You need to find a place you can try on some headsets before you buy.

Passive Noise Reduction refers to mechanical systems such as rubber seals to keep cockpit noise from reaching your ears. Active Noise Reduction and Electronic Noise Canceling are the same thing: Electronic circuits which sample the cockpit noise and feed it back to your ears with the phase inverted so that it cancels out the cockpit noise. High-end headsets from Telex go one step further and add digital signal processing that further suppresses background noise.

The result of ANR is an additional 20 or 30 db of noise cancellation over passive-only headsets. This saves your hearing and makes for a more comfortable ride.

Generally you should almost always buy an ANR headset these days, and you should spend as much as you can afford. The absolute best noise reduction is the Telex Stratus 50D, which combines passive and active noise reduction to give you over 50 db of noise suppression. One of the more comfortable but less effective expensive headsets is the Bose X. They are lightweight and reasonably effective in canceling noise. But you can get the same noise canceling at half the price from other vendors.

Zulu - $44.99 Filmed on a grand scale, Zulu is a rousing recreation of the January 22, 1879, siege of Rorke's Drift in Natal, Africa. An army of 4,000 Zulu warriors have already decimated a huge British garrison; now they are on their way to the much smaller Rorke's Drift. A Royal Engineers officer (Stanley Baker) is determined to stand his ground, despite having only a skeleton garrison at his command. His steamroller tactics are constantly at odds with those of a by-the-book lieutenant (Michael Caine), who feels that a retreat is called for, but it becomes clear that if the garrison is to survive, they'd better pay heed. Jack Hawkins and Ulla Jacobsson are also on hand as an idealistic missionary and his somewhat more pragmatic daughter. Richard Burton provides the narration for Zulu, closing the film with the observation that 11 of the 1,344 Victoria Crosses awarded since 1856 were bestowed upon the survivors of Rorke's Drift. Zulu was followed in 1979 by a "prequel," Zulu Dawn. ~ Hal Erickson, Rovi
