I am a longstanding fan of analog audio connectors, such as the headphone jack. During the iPhone7 rumors I long pointed out the many drawbacks of wireless audio: very lossy SBC -few combination support the also lossy aptX-, charging, connectivity issues etc.
While I still boycott the iPhones without headphone jack I run into the issue myself testing a Sennheiser Momemtum M2 Wireless the other weekend. Turns out on iOS Garageband does not use bluetooth by default, if you select it anyway, the App even warns about latency, and then if you actually use it iOS is such a degenerated crap, that it Garageband not allow you to use a Lightning connected audio input with Bluetooth audio out, … !!! What the heck?!?!
And when you do the Joe-user task of watching video? It is not even lip-sync anymore - the audio is seeable lagging like half a second or so, … !!!
Sad new wireless world :-/
