Excellent head set. Mostly pros and a few cons.
Pros: Great sound quality and NR. Awesome styling. NICE case. Extra battery module. Built-in carbon-monoxide detector is interesting. Assists hearing impaired. Durable cord. Well-designed control module.Cons: Price. Quirky USB adapter. No LED to tell you if the set is charging or how much charge there is, unless you open up the app.

Great clarity and comfort!!
Bought this for my son- he was really impressed with the quality, clarity, of sound, noise cancellation, and comfort of this headset- especially in comparison to what his flight school has available for students. As a mom, I appreciate all the safety features such as CO2 detection! He is excited to try the bluetooth feature with music in the future! Can’t rate this high enough! He would definitely recommend this to his fellow pilots!

Not as great as a pair of A30’s, for not much less
While I liked the design of the larger ear cups than the Bose A20s, they definitely had much more clamping force, which was a bit more than desirable. The construction quality felt a bit more premium, but the headset is definitely much heavier. Overall, still a comfortable headset, but not ideal for the price range.On the topic of audio quality, radio communications sounded about equal to a comparable pair of Boses; however, I received comments from multiple students and other pilots, both on the aircraft intercom and radio, that the Bose A20s sounded noticeably better. The rechargeable battery and ability to use double-A batteries were definitely pros, making the headset more convenient; I’d count that as good versatility over the Bose. A pause button for music is definitely a pro, and the CO detector was neat but a gimmick for the most part.The headset is definitely larger than the A20, including the carrying case, which is massive but definitely secures the headset much better.Overall, the headset performed well, but for the price tag, it does not meet its expectations given its cost being so similar to the better pair of Bose. The extra comfort provided by Bose, slightly better ANR, and smaller more compact design definitely warrant spending an extra few bucks if you fly for hire, fly frequently, or fly long flights. The Delta Zulu’s are not a bad headset by any stretch of the imagination, I just think they don’t live up to their price tag.

Better than its competition the A30s
I love these headsets! I was comparing them with Bose A30s and was going back and forth because the sound quality was similar Bose had a slight edge on clarity but these didn’t have the annoying popping and white noise I was experiencing with the A30s. In addition the CO detector has already worked for me in warning me about rising CO levels in the cabin. The headset lets you know when battery is low to recharge or swap with the other battery pack provided. The chord on Lightspeed is the best! Making phone calls with the headset is clear. If I wanted to be picky I would say I wish you can charge the battery separately, have a charge indicator light, and a usb C charge port. I haven’t tested the audio recording function. The hearing program to adjust to your hearing I can see as a great feature if you start to loose hearing as you can adjust certain frequencies that you have harder time hearing.

a 1,200 head set shouldn’t have these problems out of the box
Immediately when i put the headset on and turned on the volume there was a high pitch ringing in the right side of the headphone – not only annoying but i think it could hurt your ears. Also, the app to control the settings on the headset only works with i-phones – and I use android. This should not happen when you buy this expensive of a headset. If you are an android phone user – don’t buy. Other wise I would expect for this price that none of these issues – especially the ringing in your ear – to happen. Very dissapointed.

Audio Recording and Hearing Loss Compensation are very helpful
Excellent active noise cancellation. I compared to Bose A30s – both are equally good and are far better than the old David Clark H10-13X headset I have. I don’t think there’s any further advancement needed on the ANC technology – you don’t want to fly in total silence – a little background engine noise is an important part of piloting and the Lightspeed gives just the right amount.Very comfortable to wear. At 14oz they seemed a little heavy, but I immediately forgot about them once I had them on my head.As a new student the feature to record all audio is very helpful for reviewing lessons and replaying a flight along with the Foreflight tracklog. I specifically use the recordings to review the calls from tower that I missed or didn’t understand, and to practice hearing and writing down the key items from ATIS, and to make notes about the corrections my CFI gave me during maneuvers.I have upper range hearing loss which is what initially attracted me to the Lightspeed DZs. The “Hearing EQuity” feature setup works just like the hearing test at Costco or the test used with Airpod Pros on an iPhone. This feature noticeably compensates for my hearing loss – allowing me to focus on learning the lingo and being tuned in to my call sign.The built-in CO detector wasn’t so important to me, but I may change my mind about that if someday I hear the CO alarm announcement from the headset.Some reviewers complain about the UAC jack for connecting the charge cable. It is an uncommon jack although I have encountered it in cameras. The headset comes with a UAC to USB-A cable and you can buy USB-C and other types from Lightspeed or on Amazon. On Amazon the UAC connection is referred to as UC-E6. I expect a future new Lightspeed headset will have switched from UAC to USB-C since that seems to be becoming universal.I’m guessing Bose will be catching up on the audio recording and hearing loss compensation features in their next new version, because I am finding those 2 features to be pretty significant reasons to go with the Lightspeed DZs. I haven’t encountered any aspect where the Bose A30s have an advantage.
