Absolutely amateur hour from Lightspeed And not something that was necessary for the PFX. And not paying attention to a year’s worth of complaints. ### 1/5 — App does not work *2024-05-31, version 2.1.3* Got my new headsets and tried to make an account, the screen froze. Tried to make account on their website and then went back to app that still didn’t work. It did not recognise my account and froze again. How am I supposed access the features if I can’t make an account ???? ### 1/5 — Terrible *2024-05-25, version 2.1.3* Hard to believe a company would release an app that they tout as having all these benefits for a $1200 headset, when the app has multiple obvious bugs. Have only used the headset once in plane so haven’t had a chance to evaluate…but the app and recording features are terrible. Also, having problem with power button not working. It seems to be resolved by disconnecting and reconnecting battery ### 1/5 — Great headset, garbage app *2024-03-08, version 2.1.3* Apple really needs to figure out a way to let people rate less than one star. The Delta Zulu headset is stellar hardware held back by absolute trash software. Why bother touting recording capability if it ***never works***? At least the app let me set up custom EQ, which is nice. Shame the rest of the app is so bad. ### 1/5 — Can’t open *2023-12-22, version 2.1.2* New update won’t even let me open the app. I had to redownload twice to be able to open it. Yet again same problem ### 1/5 — App does not work *2023-11-21, version 2.1* The app usually opens and shows the only recording source is the iPad mic it is connected to by Bluetooth - completely useless in flight! Occasionally and for no reason known to me, it will show the comm panel as a source and then it will record. I have sent a customer support request from the company website but did not get a response. I finally called and they said to power the iPad down and back on. The comm panel setting came up, but the very next time I used it in the aircraft it would only give me the iPad mic. I cycled the power on the iPad and the headset multiple times but I never works. I called support again yesterday and they said they would get back to me. ### 1/5 — App Crashes *2023-10-21, version 1.1.0* The app crashes every time I open it. Useless ### 1/5 — Recording doesn’t work *2023-09-16, version 1.1.0* I bought the DZ for the recording. It worked perfectly the first couple of months. However, Lightspeed “updated” the app and not it does not record. I have contacted customer service multiple times. They never follow up with me and act like there is no issue with the recording feature; all the reviews state otherwise. It’s is very disappointing because in the past I heard the customer service was excellent, but sadly this is not the case. I should have went with Bose. ### 1/5 — Replaying of audio files is really bad *2023-09-06, version 1.1.0* It’s a very delicate system. It takes 5 mins to bring up a 9-min clip and crashes the app if over 60 mins. Extremely frustrating. Can’t gain access to audio files on homepage. ### 1/5 — App crashes every time *2023-08-18, version 1.1.0* App immediately crashes every time I try to open it. Totally unusable. It had potential when it used to work before the updates, but now it’s complete garbage. Like many others on here, very dissatisfied with lightspeeds technical department. ### 1/5 — Update bricked my headset *2023-08-07* The last update prevents CO monitor use without signing up. I found out flying xc. To ask a pilot to f-around with logins mid flight is absurd, and that’s only start. No visible concern for data privacy, troublesome purchase process, and dubious security. Stick to making headsets, you are not a tech company and it shows. ### 1/5 — Recording does not work *2023-07-22, version 1.1.0* Like many others have already said here, the app is no longer able to record comms on flights. When I first got the headset, this feature worked just fine. It seems that after the app updated, this functionality has completely failed. The recording starts, and seems like it’s working the whole flight. Then when I open the app back up right after the flight, it is as if no recording was ever started. Highly disappointing when you go through an entire 2 hour flight expecting to be able to listen back to the recording. I expect a whole lot more from this app, considering the quality of the headset it is associated with. Please fix this issue! ### 1/5 — The recording function won’t work *2023-06-01, version 1.1.0* I have tried using the recording option today for the first time, it recorded the entire flight, which was about an hour and a half, but when I tried exporting it, it didn’t work no matter what option I chose whether it would be via email ,WhatsApp, Telegram , notes, nothing worked. When I tried exporting it to Voice Memos, the app froze which left me with no other option, but force close the app. When I opened the app after force closing it, my recording was gone! It is not in my Voice Memos, nor anywhere else that I have tried exporting to and now it’s somehow been deleted from the Lightspeed app, despite me never deleting it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Recording STILL doesn’t work *2026-06-30, version 2.2.1* I feel dumb that I didn’t read these reviews before I spent so much money on a headset. As others have mentioned, mine won’t record using any microphone source other than the iPhone internal mic. Of course this is useless in flight. I called support and instead of admitting this is an ongoing issue, the guy acted like it was the first time he had heard it. I jacked around with installing, uninstalling, trying different devices, turning off Bluetooth connections on my aircraft radios, sending screenshot videos back and forth to the tech support guy, etc. I’m really ticked off that they continue advertising this function when they know darned good and well that it doesn’t work. It really makes me want to send the headset back and demand my money back even though I’m past my trial period. People respect me and my opinions on a very well known type forum and I will be sure to share my experience with Lightspeed. Updated to add: I see that Lightspeed has provided a response telling me to contact their support line. Believe me, I’ve spent HOURS working with their support people. I’ve completely factory reset my Garmin radios, I’ve tried 3 different iOS devices. I’ve tried their app in all 3 of my planes as well as a PC12 and a Vision Jet I sometimes fly on contract. I’ve uninstalled and reinstalled their app. Ive tried old versions of their app. I’ve sent them freaking screen grab videos of what happens when I try to use their app. Look up the definition of gaslighting and you’ll see that it was invented and perfected by Lightspeed. Their headset form factor fits my head and is more comfortable than their biggest competitor in the ANR field, but that’s the ONLY reason I still own them. The other popular brand sounds better and all their advertised functions just work. I guess that’s why I’m the only person I know who owns a Lightspeed and quite literally every other pilot I encounter uses Bose. ### 1/5 — Recording not working *2026-06-19, version 2.2.1* I purchased the Zulu 4 over the Bose A30 specifically for the ATC recording function since I’m starting flight lessons, but it doesn’t work. Only my voice was recorded the entire flight. I made sure to select ATC and ICS, but it isn’t working. ### 1/5 — Doesn’t work *2026-03-10, version 2.2.1* The headset cannot be connected to the app using Bluetooth! Their recommended app FlightLink works. So why keep marketing this app? Just remove it! ### 1/5 — Recording does not work *2026-02-16, version 2.2.1* As others have mentioned, the recording function does not work. This is my first Lightspeed purchase and unless they knock it off with the denial “edge case” BS it will likely be my last. ### 1/5 — Recording STILL doesn’t work *2025-11-23* I feel dumb that I didn’t read these reviews before I spent so much money on a headset. As others have mentioned, mine won’t record using any microphone source other than the iPhone internal mic. Of course this is useless in flight.

If by chance an update is made before my return period, I’ll keep the headset. ### 1/5 — Can’t login. *2025-03-24, version 2.2.1* Tried resetting the password, numerous times, still can’t log on. This is ridiculous to spend $1000 and not be able to use the basic functions. Interestingly, you can log onto the website, but not the app. ### 1/5 — Unable to use when not logged in *2025-03-08, version 2.2.0* Getting co warning enroute but unable to see trend because app was logged out. Also does not support autofill from password managers. ### 1/5 — Won’t connect *2025-01-19, version 2.2.0* Bluetooth on my phone paired the zulu3 but the app won’t recognize the headset making the app useless- and the login isn’t the same as when you login to the website which is silly. Really disappointed as I thought I was getting a good deal not going with Bose - maybe I was wrong and Should have stayed with what everyone else does. ## Most praised reviews (8 highest-rated) ### 5/5 — Outstanding performance *2024-07-31, version 2.2.0* Safety features and clarity are awesome ### 5/5 — Second to none. *2024-07-23, version 2.2.0* Best headset ever. ### 5/5 — Very Disappointed *2023-11-01, version 2.1* I am very disappointed with this app as well as the Delta Zulu headset. The app locks up and the recording function does not work. Also poor communication from Lightspeed regarding issues and updates with the headset and app. ### 4/5 — Neat App, but it could be more *2023-03-21, version 1.1.0* The audio recording in app is awesome, the CO monitoring is near real time, and the ability to track all of your metrics in an exportable spreadsheet is neat too. For such an expensive set of headphones it feels like the app could look better and provide more features. ### 3/5 — Battery charging inaccurate *2026-05-10, version 2.2.1* All in all, not a great app for what is possibly a great headset My biggest bug is the battery charging meter is not accurate at all when it’s on the charger I’ve seen it swing from 80% to 55% to 15% while charging ### 2/5 — Great idea, but buggy *2026-01-27, version 2.2.1* The recording feature is super buggy. Sometimes it doesn’t recognize the headset is plugged in so it only tries to record using the iPad microphone. Other times it seems to stop recording for no apparent reason to me. Somehow, I’ve ended up with a zero length recording that freezes the app anytime it’s selected. So I can’t delete it from the library view of the other recordings. ### 2/5 — Getting worse? *2023-05-30, version 1.1.0* Like many I got the new Delta Zulu headset for the CO monitoring and the recording. The app is a bit flaky, but the latest update has rendered the recording feature almost useless. Since it stopped on my previous instructional flight I checked it constantly on my latest solo flight. When I finished 6 hours of flying through the day, I had 1 minute and 42 seconds of one flight and 37 minutes of the other….. No clue where all that recording time (and battery drain) went! The app will start recording but every time you go back into it, it looks like first time opening the app and it doesn’t show any recording is ongoing (But recording icon is still active for iOS). Hoping that future updates will restore functionality… But for now don’t count on it… ### 2/5 — ATC Recording - No chance! *2023-04-17, version 1.1.0* Tried for weeks to get the App to record the cockpit comm for flight training and ATC conversations. It worked once. The app crashed each of the next 7 lessons. The recordings all stopped after 11 to 15 minutes. It was a reason I purchased the new Delta Zulu headset in the first place. Contacted tech support many times without getting a resolution and I’m a techie guy. I --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
