The Zulu 3 headsets were so much more comfortable then my Bose A-20 s that I purchased them for my helicopter...

This is my second Zulu 3. I bought the first a couple years ago and its worked great. Its very comfortable and the sound quality is excellent. I bought this one for my wife who has taken an interest in learning to fly some 20 years after I got my licenses. The Zulu fits her well showing it can accommodate a range of sizes - shes 5 3 and small build, Im 6 and medium. I have used a Bose also and found the sound quality and comfort between the 2 to be no different. I like the larger ear cup of the Zulu as I do have larger ears. I found the Zulu to fit me better than the Bose. Ive seen many reviews which state the difference between the two comes down to personal preference. I agree with that. My only dislike of the Zulu is that the mic boom cant swing back to allow the head set to be turned around and allow the person in the right seat to have the cable be on the right side, a point other reviews also raise. As a result, if sitting on the right, which as a CFI I do a lot, the cable has to cross over your chest. It would be nice if to compensate for this the cable was just an extra 6 longer. I fly predominantly in PA28s and I have to place things properly to get headset control in the right side storage pocket to leave enough slack to keep free. It is not a big deal and has never caused a problem. Most people probably wont have an issue. But being 6 tall I sit further back than most people. I dont consider this to be a reason to drop to a 4 star rating especially given the plus side of the cables t Kevlar outer cord. No worries about that cracking or breaking. Bottom line, comparable sound quality as the Bose, comfort is excellent and comes down to personal choice between them, and $100 less (one extra hamburger lunch in aviation terms).

Had been along time since flying with an anr headset. I had been just using a trusty green headset like I give all my passengers. Decided to spoil myself for Christmas. Wow I had forgotten what I was missing. In coming radio calls are a lot more clear. How many radio calls was a missing before when I could not understand what they were saying? Tell your wife you need these because it is a safety concern not having them ) I shouldn’t tell my secrets... But it is true.

Ive never experienced an ANR headset before so maybe not the best 5 star rating. Ive gotten 1 hour in the plane with them. Actually I was totally impressed with the improvement in everything audible. Actually slid one side off during runup, learned something you really have to keep them sealed around your ears or they will complain at you. Im totally not concerned about that anymore. Bluetooth was no problem connected to my phone just fine. Tried one phone call it seemed a little awkward but wasnt anything to do with headset mostly chatty radio folks. Tried music stream this was so cool. Looking forward to getting a second set just so I can watch the look on my wife and my sons face when they turn the power on. When I started I didnt even use headsets, flew into Memphis Center with nothing but a speaker, hand mic, and my endorsement. Crazy right, well this was as big a step up in my opinion as it was when I tried my first headset and thought why, why did I wait so long.

Used this to replace my Telex Stratus 50D I have owned for 15 years. I think the speakers are getting worn out and muffled. I owned Bose A20 previously in a different airplane and found 1: ear cups sat on my ears not over 2: very noisy if battery died in flight. Zulu 3 fits over my ears and has reasonable passive noise reduction. In my Cessna TU206G, if the pilots window is open while taxing and ANR is on with the Zulu 3 I get a fluttering noise in the right ear. So I close the window or turn off the ANR.

Q: I have had many Lightspeeds over the years, I have a ZULU 1 now and it has performed great. My question is, is there any difference in the noise cancelling of the 3 compared to the 1? See you at S-n-Fun Bob Stebbins

Yes, the noise cancellation capability did improve slightlyu from the Zulu 1 to the Zulu 2. The Zulu 3 has the same noise cancellation capability as the Zulu.2, however the improved ear seals on the Zulu 3 will provide a better fit and seal.

Q: Can the mic boom on the Lightspeed Zulu 3 Headset be changed to the other side?

No, the boom mic cannot be swiveled all the way around. The boom mic will be on the left side of the head.

Q: Do you offer a trade in discount for a old set of Lightspeed headset?

Yes, we do. Please search "Lightspeed Trade" on our website to see the trade in options we have. The first two results pages will show you the current trade in values for your model headset.

Q: Are the seals one size fits all for Zulu 1, 2, & 3 ?

Yes, the ear seals part # 11-08043 will fit all 3 generations of the Lightspeed Zulu 3 headset.

Q: I have two of the Lightspeed 30 3G panel power by LEMO connector headsets in my RV-9A. Can I get two Zulu 3’s with the same panel power setup?

Yes, the part number for the 6pin Lemo version of the Zulu 3 is Part# 11-14870.

Q: Can the ear pieces on the Zulu 3 be folded inward for storage which I believe they can on the previous models (or so they would appear from the photos of the previous Zulu)

No. The ear pieces twist sideways for storage but they do not fold inwards.

Q: Lightspeed Zulu 3 LEMO, if this headset with LEMO plug has also posibility to power from batteries? In my plane i have LEMOs, but if i want to take headset to plane without LEMO and connect them thru GA-LEMO adaptor, i need to power them by AA batteries.

Yes, that is correct. If you use a LEMO Zulu 3 in a dual GA aircraft with an adapter, you would need batteries to power the ANR.

Q: Regarding the Lightspeed Zulu 3 headset, does it require any sort of adapter to connect via the bluetooth with a cellphone?

No, the Bluetooth functionality is built into the cable assembly.

Q: Is this Lightspeed Zulu FAA TSO approved?

Per the manufacturer, they are not TSO approved. However, All Lightspeed headsets are tested to FCC and CE certifications, internal environmental standards, Apple MFi program standards (if required), and meet performance requirements of the FAA to be used in any civil aircraft.

Q: I received my new LightSpeed Zulu 3 Headset yesterday. Does my free survival kit arrive separately?
