Michael WolfStaff PIREP

"I was amazed the first time I flew with the Zulu PFX. It's simply the quietest headset I've ever worn. And since I jump between different airplanes, the FlightLink app is a handy way to customize the noise reduction settings."

Plus: Quietest headset I've ever tried

Plus: Great audio features and quality

Plus: New features available with upgradeable software

Minus: Only average battery life

Minus: Large control box (but it does a lot!)

Lightspeed Trade Up Program

Tired of your uncomfortable old headset? Now you can trade in that old headset toward a new Lightspeed headset and save up to $350. Here's how it works

Which cable do I need?

Most headsets come in multiple cable configurations. Choosing the right one is pretty easy, it just depends on what type of aircraft you fly:

  • Battery powered, twin plugs - this is by far the most common style, with separate microphone and headphone plugs (so-called PJ plugs). Almost every airplane ever built has these two plugs in the panel, so these headsets are universal. The only downside is that, for ANR headsets, you will need to use AA batteries to power the headset.
  • Aircraft powered, 6-pin plug - the second most popular style, sometimes called the "LEMO plug," requires no batteries since it is powered by the panel. This is convenient, but it does require the 6-pin plug to be installed in the panel. While many newer airplanes come with this option, most older airplanes do not. For these applications, you'll need to have your avionics shop wire in the plug - not a big job, but not something pilots can do on their own.
  • Helicopter plug  - helicopters use a single, shorter plug (that is not compatible with airplanes). This is not like the 6-pin plug above, however, since an ANR helicopter headset will still need AA batteries. The only confusing part is that some helicopters also have a 6-pin (or LEMO) plug. In these helicopters, there are two different single plug connections.

Headset plug versionsWhen in doubt, we recommend buying the battery powered, twin plug model. This is the most universal option, and will work in almost any airplane. If you have a 6-pin plug in your airplane or you plan to install one, the aircraft powered model is a nice option.

Pros: Noise canceling is at a whole new level. Super easy setup and use Seems to be built very sturdy Sound quality for ATC as well as music is awesome Cons: Control box is a little bulky but that hardly matters if you have a place for it. I was expecting more from the iPad app, its basically just a recorder. This is a great headset. I upgraded from a Telex Stratus 50 and I am impressed. The noise canceling is almost scary quiet. When you first turn it on you think 'ok, not bad active noise canceling', then a few seconds go by and it goes into a whole different level of noise cancelling. The outside world all but disappears and anything coming across your radio is crystal clear. Its a hefty price tag but when you are talking ANR headsets these days the extra you pay for these hardly seems to matter. I would get them again without question. Passive noise reduction actually isn't bad for a small framed headset either.

Pros: It was markedly more quiet than the Zulu 2s that I have had since they came out. The Zulu 2 was better than the Bose A20 for my airplane. Terrific music reproducibility and the ability to boost base/treble for personal preference is a great feature. Cons: The battery/computer is larger. That is the only con. Lightspeed did it again.

The Best Headset I've Ever Used! Period
I've been using this headset for about a month now and it has exceeded my expectations in so many ways, I can't even find the words to describe on here. I've tried the Bose A20 and while it is a great product, something about it didn't sit right with me, it felt heavier, it wasn't as comfortable, it wasn't as quiet, as I expected. The biggest turn off for me was the hinged top which effectively created a weak spot, coincidentally, the exact spot my coworker's A20 broke while expanding to put over his head. Might have been other factors, but that was enough for me to look elsewhere. After trying another coworker's Zulu.2 from Lightspeed on a four hour cross country flight, I was already bought after taxiing out to the runway. So I started to research more about Lightspeed and was impressed by reviews from all over the internet. I decided to jump in and get the Zulu PFX and man do I have to say, "Best purchase EVER!" The headset was purchased from Sporty's Online and was delivered on time as expected. This thing is QUIET! I fly a Cessna Grand Caravan commercially about 6-8 hours a day, 6 days a week and this is by far the best headset I've ever used. It immediately goes quiet when you power it on, then about 2-3 minutes later, you can hear a second level of quietness kick in. Later on in the flight, you'll notice that somewhat of a third quietness level, or maybe just perception, but it gets so quiet, the only engine sound you "hear" is what you "feel" through vibrations in your feet. The headset cord is rugged, it feels like it can support my body weight if needed. It has a great look too... Like a plaited cord. And the plugs fit snugly into the receptacles. The audio quality, out of box - with no tweaking via the app, is superb to say the least. ATC, Intercoms and music via Bluetooth is comparable to high quality headphones with ANC. The audio priority is a nice touch - it attenuates playing music whenever a transmission is received, either from ATC or intercom - but it can be annoying with "chatty" customers, so I turn it off and have the music volume low. The lightness of this headset is unreal - I quickly forget that I have it on, there's no pressure on your ears/head, and it's so light... The ear cushions are super soft but firm and create a perfect seal even with Ray Bans on. I HIGHLY recommend this headset if you can afford it right away, if not... Start saving, you won't regret it! Having said all of that, here are a couple things I didn't like about it, however, all of these I can live with. But if they ever fix these issues of mine in a future release, I'd not hesitate to replace this with that edition: The computer box is HUGE! Bigger than I expected, and heavy... It's like they took the extra weight from the headset and throw it in there. It's is bulky too and I had a big problem finding a place in the Caravan to hook it up during flight. The headset speaker "cups" are hinged to allow a better fit, but they feel frail in your hands if you pick up this headset one handed by the cup - a bad habit I picked up working with other headsets - as they will swing under the weight of the unit and give you a mini heart attack as it feels like you just broke it, but you shouldn't be doing that any way. The app to control all the amazing features of this headset is ONLY available on iDevices - iPhone, iPad, iPod - which according to Lightspeed Technical Support, is the most used devices by pilots. I have an iPad, but my primary device I always have with me when flying is my HTC One M8 - an Android phone - so tweaking is done mostly on the ground. As I said earlier, these problems are not problems, and I can live with them all - since I found a place to put the computer box - so I did not let any of these negatively affect my ratings of this product. I hope that my review helps you make a decision, and I hope you buy this headset. Protect your hearing! You won't regret it either! Thank you.

Pros: The ANR quality is outstanding. Especially the 'Acoustic response mapping' is quite good Cons: The controler is big and bulky Pricy Had a Zulu and Zulu.2 before and the active noise reduction is better in the Zulu PFX, but make sure you have space in your cockpit for the controller. The shipping service from Sporty's was great.

Pros: The ANR is very good in flight. As others have noted, there is a basic level of ANR once you initially turn on the headset, but an even quieter level of ANR activates after a few moments. Music sounds very, very good thanks to the Front Row Center feature. It's definitely the best quality I've heard from an aviation headset thus far. I especially liked that you can adjust the treble and bass settings for both ATC and auxiliary audio using the FlightLink app. The auto-shutoff is a very handy and useful feature that works perfectly as advertised. No more wasting battery life! Cons: The insides of the earcups have hard plastic/metal bulges covered by some fabric that contained the ANR equipment. These bulges protruded just far enough for my ears to be constantly touching them when I was wearing the headset. No matter how I positioned the headset, these pieces would be in constant contact with my ears. It was uncomfortable and very distracting during flight. This may not be the case for others, but it was a deal-breaker for me. There was distinct and sometimes painful popping sound whenever I turned the headset off. The control box is huge - much larger and heavier than I expected it to be. If you don't have a pocket to set it in or a good place to clip it, you are going to be very annoyed by it. The volume controls can be difficult to change in flight as the sliders have a bit of friction behind them. Overall, the PFX is an excellent headset, but it may not be for everyone. I would definitely recommend taking advantage of Sporty's 30-day return policy and trying out all of the headsets you are looking at before you make a final decision.

Terrible Popping Noise - Notes about Lightspeed, Bose, & Sennheiser
PROS - Nice build quality - FlightLink app is cool - Great music fidelity for an aviation headset CONS - Painful POP when ear seal is even partially broken - No bluetooth music controls to FF or REW - Cables seem a bit delicate DETAILS I rarely write reviews, but this is a big purchase and I hope my experience is valuable to others. I recently bought the Zulu PFX headset with high expectations. A month ago my Sennheiser S1 Digital Headset was stolen from my car and I needed a replacement. While I had really liked the Sennheisers for the past two years, I had heard a lot of good things about Lightspeed Zulus and thought I would give them a try. I was really pumped about the FlightLink iPhone app to control the audio and record the flight audio. When the PFX arrived, I was excited to try them out. I first pulled them from the nicely packed box at home to try out the bluetooth music. The build quality seemed good, although the braided cables seemed to be a bit thin and delicate. The bluetooth pairing process to my iPhone was straight forward. In a quiet environment they sounded great (even better than the Sennheisers), great highs and solid bass. They are comparable to decent cans I have at home. I did feel the pressure on my temples was a bit excessive though. Many reviews mention the large size of the control box, and they are correct. 4 AA batteries and you have a very big, heavy unit. No worries, I felt I can chuck it in the side pocket of the 172 or the center console of the Cirrus. But when I went to control the bluetooth music, I was surprised and disappointed to find that the Zulus have no ability to skip forward or back. Even with the huge control box, they neglected to add the buttons to control your music. And they certainly have a lot of space on that massive control unit for a few more measly buttons! Not a big deal at home because you can punch the soft buttons on your iPhone. But I don't want to be fumbling for an iPhone while I am flying, trying to bring up the iPhone music controls just to skip a song. So I called Lightspeed and they just said 'Sorry, we didn't add that.' This is a major oversight in my mind as the bluetooth music was one of the big reasons I bought the Zulus (and originally the Sennheisers) vs the Bose A20s (which have no bluetooth music capability). I explained to Lightspeed that my Sennheisers had great controls for the bluetooth music and phone functions, but again they shrugged it off. Not very good customer support or product planning in my opinion. The most unpleasant surprise came when I flew them today for the first time in a SR22. When we fired up the engine, the ANR was decent, but nothing spectacular. But when I tried to adjust the headset or make any significant movement of my head, I would get a deafening POP in the headset. As an electrical engineer, I know that comes from a poor design, the ear seal breaking and the massive change in interior sound pegging the noise cancellation circuit. Good designs would filter and noise limit the input to avoid this kind of an audio spike. At first I thought it must be a fluke, but it happened repeatedly on the flight. I wear Ray Ban prescription sunglasses and they have a bit thicker temple, but every time I made a movement that partially broke the ear seal - an excruciating POP!!! It probably happened 20 times in a 90 minute flight. My ears are still ringing hours later from those extreme audio spikes. I feel like I just walked out of a deafening rock concert. Lightspeed's engineers really need to address this. I am grateful to Sporty's for their 30 day trial period. Unfortunately I have decided to pack up the Zulus and send them back. At the same time, I have ordered a new pair of Sennheiser S1 Digitals. While the Sennheisers do not have quite the music fidelity of the Zulus (a big surprise given the Sennheiser name), the great bluetooth controls, the comfort, and lack of annoying POPs motivated me to buy another pair. Also, while the Sennheisers do not have the audio adjustment capability of the Zulu FlightLink iPhone app, they do have hardware switches to boost the treble for my 53 year old, high frequency-challenged hearing. FYI, when I was training for my private several years ago, I used the Bose A20s a lot. I thought the sound quality and ANR were good, but I really thought bluetooth music would be good for longer cross country flights and I was right. If Bose added real bluetooth music capability, or if and when Lightspeed can fix the horrible POP and add bluetooth controls, I would gladly try them out. In the meantime, my Sennheisers still seem to be the best all around product on the market.

Best I've Ever Used!
PROS: Great fit. Quiet beyond belief. Superb ANR. Ability to tweak treble and bass to fit hearing is unique and music to older ears. Love the recording/playback in flight capability through bluetooth (never have to ask ATC to repeat a freq, altitude, or clearance again). CONS: Haven't found a single one! Pricey, but definitely worth it.

A shopper on May 9, 2017
BEST ANSWER: I chose the Lightspeed and have been very happy with them. excellent noise cancelling and VERY comfortable. Well worth the price, I bought TWO, one for me and one for my wife.
WIth the Bluetooth cell phone connection, does the headset microphone work when you make an outgoing call, or do you still need to talk into the phone microphone?
John W on May 8, 2017
BEST ANSWER: When you make a call you will use the microphone on the headset.
