A lot of coworkers I fly with use the Sony ones. I have not asked them about it. Let me see if I can query some people this week.
There are also a lot with the Bose, one guy swore by them as the best they have ever owned.
The low end noise cancelling definitely have the hiss, which is why I tended to the higher priced models.
As for the Jabra Elite 65t, they may block the noise, but they don't seem to have noise cancelling. This is kind of like my Shure headphones that are like ear plugs for blocking some outside sound. The review sounds good for a home or office environment. I am doubtful of their effectiveness on a plane.
Bluetooth is a technology with lots of issues. The different versions are not necessarily compatible with each other, and you have to make sure your iPhone supports the standard the headphones support. Even then, we have Apple screwing things up where their Bluetooth gets "upgraded" and no longer can interact with current devices. It really upsets me that my iPhone 6 running iOS 10 could communicate with my 2012 car just fine, but iOS 11 on an iPhone X falls flat on it's face (...your phone does not support wireless voice commands from the car and my Plantronics headphones). At least I can talk over Bluetooth (headphones and car) if I look at the phone and make it do the call. Handsfree is broken, reported, and their 2 attempts to resolve it has failed.
Honestly you should not get a signal block with your body, this is radio, not line of sight. Latency should be expected, and I believe that video players should have options to delay the video by subseconds to match the audio. Disconnects should be rare, unless one end or the other is a cheap implementation.
I have not been impressed with Bluetooth audio, so I have stuck with wired for now, plus the plane I use still prohibits Bluetooth mid-flight, but does not notice the dozen people using Bluetooth.
