Full Flight | United Airlines 737-900ER Cancun to Houston 

Can you hear how good it sounds during the engine starts and announcements? The audio quality is excellent.

This is such a relaxing and peaceful video!

I'm trying to determine if in fact this change of the audio quality affects the inner ear, because when it "closes up", I feel it in the vestibular nerve and get a headache, even though I turn it down. If I could, I'd like Emory University or Georgia Tech to analyze in FMRI and FMRA tests whether the change actually causes the fluid in the inner ear to become compressed more or what happens, because I have Trigeminal Neuralgia, and no matter how I try to adjust to the change, it becomes nearly impossible to listen to any of these inflight videos when the audio bandwidth goes from that wide, open sound to this narrow, compressed audio. All I know is that I hope I can convince you wonderful RU-vidrs to keep that audio quality you had during the start and taxiing of the airplane. I can tell you one thing. I've also experienced what others feel when they listen to the lower-quality audio. They sometimes say they get a buzzing feeling. Because I also have Tinnitus, my ears hiss for hours after trying to enjoy the flight.

Oh no! Right at 14:30, at the start of takeoff, the audio closed up as if the stereo just "floded" up between my ears and sat up right on top of my head! There's a definite change there, and I wonder if you changed the resolution? It's kind of like waking up from the best dream you were having.

I agree it seems that you downgraded the audio quality at some point. So sad. It was soooo good at the beginning.

Nice sunset

While it was taxing in the beginning of the video it sounded like they shutdown their engines.

Even the rumble of the engines changed, and we no longer hear that nice, low vibration of the engines. You'd need to put on headphones to understand what I mean. It's a shame, because that was really a let down.
