Thank you for your comment and welcome to the community.
I am very sorry to hear you're having this issue, but I would love to assist you with this.
Regarding your 1 second lag with Bluetooth whilst watching video, I would like to inform you that a slight delay when using Bluetooth to watch video is normal, This would account for internal processing in the source as well as the processing being used by the headset.
Some people have resolved this through a product reset. Instruction on how to do this can be found below.
Regarding the cable issue, have you ensured that the cable is fully inserted into the headphones? Also I would recommend trying another audio cable to see if your original cable is causing connection issues.

Flight back from Australia to NZ with airnz yesterday, still had the same issue, however quite by accident I pulled the plug out of the jack on the monitor I heard talking.
So didnt need the adaptor, just didnt need to push the plug all the way in to get sound
so maybe an issue with the design of the headphones cable?

We are in France, so it will be awhile before we can test an airline plug again.
The cable works OK on my iMac. I had not noticed a big end and small end, but it is unlikely to have reversed it since the big end does not fit into the headset.
The "Battery 100%" message is a sure sign that I had turned the Bluetooth switch ON. The headsets work nicely with a cable even when that switch is OFF. My previous Bose headset had an ON switch. Is ON necessary for Noise Canceling or do the new headsets gain power through the cable, not the battery ... or does inserting a cable turn the power ON?
I will fly with a converter from Big to Small end ... and I will bring an extra cable in case not all BIGs are the same.
