I'm so "technologically disadvantaged" that I don't even understand Adam's question!

His question translates to: Why is there a delay between the video and the audio when watching/listening on my iPhone 7 via Bluetooth i.e. wireless earpiece or wireless speakers. In other words, why aren't the video and audio synced, why is there a lag between video and sound..

And the other issue is that the iPhone7 doesn't have an earbud/headphone jack.. So as Adam said, the primary audio source/connection is via wireless Bluetooth..

And one more note: that is primarily an issue when trying to listen privately i.e. on an airplane, in a public situation, when the listener doesn't want to share the content or disturb those around them.. Previous iPhones, like other mobile phones, had wired headphone/earbud jacks.. It is still able to be connected to audio/video speakers etc. via a "lightening cable/USB connector/charging cable" etc..

Andddd... the final answer is that it's a common problem with Bluetooth connections, to have the audio latency problem..and not just on the iPhone7, although the lack of a headphone jack makes it a bigger issue for the iPhone7. Perhaps Apple will come up with a solution..

Glitzy, you always keep us informed! What would we do without you?!! :):):)
