Lightspeed Delta Zulu

I ended up returning my DZ and going back to my Z3. There are some conflicts between the DZ and the GMA1360 3D audio. Lightspeed tracked these down with Garmin and expects to have a fix in Q2. I'd like the benefits of the equalization so I'll try it again in 3Q23.

i bought the Delta Zulu even though I have 2 A20’s and 2 Lightspeed Zulus in the plane already but had to have the “latest thing”. Been very disappointed. Two in a row, when plugged into the LEMO port, immediately start squealing at a high pitch (which I can easily hear without any equalization!) So, I’ve given up on these things. I think this may be a common problem because when I reported it on the first one, they were quick to issue the RMA for return. If I can trust the hearing test, my hearing is pretty ok (need some augmentation at the very highest frequencies) so that feature is not all that valuable and the Sentry I use as a second source for ForeFlight already does a CO warning…. So, back it goes.

I love my Lightspeed headsets and I love the company.

I believe that it is probably emblematic of what has happened to a bunch of American companies, though. They started by designing and engineering their own products but over time the offshore companies that were doing the manufacturing offered more and more services and it was impossible to match those prices. Need a new battery case designed for the top of the line model? We can send you shop drawings and then sample manufactured pieces. Need a circuit board designed for the new bluetooth feature integrated into your active noise cancelling? We've done that dozens of times.

And they have amazing customer service, their repair rates for me have been totally reasonable. But I don't think that they are really connected with the process of creating a product anymore, which is unfortunate. I don't think that's how you make the best stuff.

Norm, did you try the Delta Zulu with the disposable battery case installed (without batteries, since the LEMO jack provides ship power to the headset) rather than the rechargeable battery case? In my DA62, the latter injects a squeal into the headset most of the time (but not always, which is odd/interesting), while the former has never injected a squeal.
