CVO

I have not tried my Lightspeeds in any other aircraft. It could be my AC? When explaining to Lightspeed customer service that I do not have any popping noise with my Bose A20s, they dove into an in-depth explanation of the Zulus ANR engineering which seems to simply mean that they are highly sensitive to any environmentally noise. So, yes, many things can easily compromise the fit/seal and could/can contribute to the noise problem I have. As I mentioned, both passenger and I tried repositioning the cups around the ear, applying different pressure to the ear cups, removing sunglasses, ball cap and all the other test dummy stuff we tried – unfortunately, none of those things worked. Getting a new Mooney is out. Can’t get 2 new heads w/ better ears. Might have to live with Bose – which served me well for the last 10 years.

I have the same popping issues with 2 Lightspeed Delta Zulu’s I purchased - on the ground, taxing, during takeoff, climb and level flight – both seats, both headsets. I have been working with their customer service and engineers to find a solution. They are aware and have a host of factors they feel cause or contribute to the noise – volume control, disconnect mic, open doors, vents, cap, glasses, seal/fit on ear seals, engine noise…I’ve tried them all and nothing changes. They tried a software change with a new app but that didn’t help. They now have a new Beta test headset that they sent me but that didn’t improve the problem at all either. I have Bose A20s and do not experience any of these problems. Obviously not all Lightspeed users have the same or even any negative experience. Unless we/they can find a solution, looks like they will get returned. Frustrating - I like their features and comfort, but the popping noise is a big distraction and deal breaker.

Done - Thanks
