Pilot Stories

Having flown with the Zulu PFX for several weeks, I can say that it is the quietest headset I have used and certainly with the most advanced audio processing. With PFX, Lightspeed has moved active noise reduction up a notch...
   — Tom Haines, Editor in Chief, AOPA Pilot
Lightspeed has been on a technology march toward ever more comfortable and quiet headsets and the new Zulu PFX making its first Oshkosh appearance is remarkably good. The new Zulu matches the Bose in price, and many of us who have tried it believe nothing is quieter or more comfortable than the Zulu PFX. But that's a personal opinion.
   — J. Mac McClellan, Editor in Chief, EAA Sport Aviation
Far Exceeded My Expectations
Lightspeed's ANR creates an entirely new atmosphere in the cockpit of my 1946 Luscombe. When I preformed my first radio check with the local Unicom using the new headset, the FBO asked if I'd bought a new radio! Over 53 years flying, with 18,000+ hours and 14 transport type ratings, I have never flown with a better headset.
   — Gary Schaffer
The PFX kicks the crap out of everything else I have ever worn. The are _slightly_ better than the Zulu 2s which are still very good cans. It is amazing what a difference it makes to the Sonex environment. I can hear the engine, I can hear everything I need, but it just makes it a much nicer place to be. Transmit clarity is far improved. No idea what they did here, but the Halos make it sound like I am transmitting from a noisy place. Not so on the PFXs. Huge improvement.

Best headset on the market!
At first I was a little overwhelmed by the size of the ANR box but it's actually a great setup especially with the metal clip they provide. I find it more convenient and comfortable then my previous Zulu. With the clip attached, I can usually find something in the cockpit to mount it to. Max flight time without taking it off was 3.5hrs and I could've still went another 3.5+ hours with it on. The music quality is phenomenal! (Especially when combined with the flightlink).
ANR on this headset is the the best I've ever heard/experienced. It has 2 modes to select from. The first level is your typical first and second gen Zulu's level of ANR then when you switch it to the second level it's almost doubling the amount of ANR (this is where this headset really shines). I've tested it out in a Cub, Acrosport with a canopy, Twin Comanche, TBM700, and a CRJ700 within the past week. In loud open cockpits (cub), you have to keep the headset in the 1st level of ANR but even with that it's just like having a previous version Zulu so no big deal there. Flying in the Twin Comanche with headset in the second stage of ANR, there were moments when I wondered if the engines were running, it's that quiet. The TBM was even quieter and the RJ was very very very very silent. The RJ has avionics fans that are pretty loud and this headset knocks that sound out. When I have the music going and the headset on level 2 in a turbine aircraft I can't hear anything outside of the headset (even other people in the cockpit not on the intercom). So with all of this said, this is without a doubt worth every penny of $1100!
   — reviewer BCM25,
  I tried this at Oshkosh and the new PFX blew me away. I have hearing loss, and have progressed from a Bose X to a Zulu to a Zulu 2 ... each one better than the last for hearing clarity. At OSH they had the new Bose A20 next to the Zulu PFX. Simply no comparison. The PFX sound quality and clarity was markedly better than the Bose and a definite improvement on even the Zulu 2. Some may not need this, but for me it is indispensable.  
   — reviewer Scott Sedam,
  I fly a 1969 C-182 O-470, great plane, deep throated and loud. I also wear sunglasses on just about every flight. Just about any headset is vulnerable to allowing noise leaks when wearing sunglasses. The Zulu PFX limits the noise leaks actively. Thats the only explanation I have for the quietness that I experienced when using them for the first time. The Zulu 2's are good but in my opinion the PFX is a true class of its own. I still have the Zulu 2 and it's for passengers but the PFX is a great step up and to me worth the money as its a totally different experience from all the other big names in ANR including Lightspeed.
