i got the same tv.
I pulled out them glasses about a month ago and they are totally dead.
oh well..
I pulled out an old set of Bose QuietComfort headphones (wired) to take on a trip three weeks ago. Dead. New battery. Still dead. Cleaned contacts. Dead. Frustrating.
Fortunately I had my much newer Sony wireless headphones with excellent noise cancellation. Makes flying so much more comfortable. I hate to toss the old Bose headphones, but I think that’s all I can do now.
