It’s complicated, but basically, when audio is playing (I.e. new audio session) that’s when the BT headphones wake up. So you can get horrible initial delay (and missed audio in some configurations), unless you just broadcast a null signal to keep the connection alive.
I’m assuming that’s why all the popular USB “Bluetooth audio with aptX” all identify as an audio device and handle pairing etc. on their own. (Despite Windows’ stack having aptX support)
- Miraste 4y agoI've run into that before too, but I'm talking about the latency when an audio session is already running. There's a latency test in this review of the headphones I have: https://www.rtings.com/headphones/reviews/sony/wh-1000xm4-wireless https://www.rtings.com/headphones/reviews/sony/wh-1000xm4-wi... It's actually worse than I remembered. The iOS latency is 38ms and the Windows latency is 5.5x longer at 212ms. It's bad enough that watching videos is very annoying because the sound is visibly out of sync, and if you look through the other rtings reviews, this is about average for Windows Bluetooth.
- MichaelZuo 4y agoWow, a 5.5x difference for the exact same headphones is laughably bad.
