Glad to hear it's not just me. Happened repeatedly on my flights I took last week. I have had all 3 generations of the Pros, this is the first time experiencing this. Also left AirPod only.
Seems to leave the hearing impaired party as an outsider that is observing the conversation. Great step forward to giving the hearing impaired a foot in the door, so to speak. I'm curious to see where tech like this continues to develop to create an equal playing field for the hearing impaired within the conversation.
