A cool project, when you want to use AirPods outside of Apples ecosystem. Sadly, you have to use a rooted android device with a small patch due to a bug in the Android Bluetooth implementation. https://issuetracker.google.com/issues/371713238

Any idea how much latency there is between the beginning of audio being played in an app, and it then coming out the headset?

I use wired headphones to study with Anki (AnkiDroid) because I've found most (inexpensive) Bluetooth headphones require a second or two to begin playing. As I'm dealing with short audio clips, this use case necessitates restarting the "audio playing" situation every few seconds.

Maybe the app developers could "play" quiet audio between these short clips. But barring such a development, I'd like to know if higher quality headphones might suffer from less latency in this regard.

This is your host idling the connection due to the silence. Just keep something playing (like a stream of almost-silence) on loop and you won't have this problem.

Yes, but I was asking if high quality or newer Bluetooth audio devices have a lower latency.

I will suggest to the app developers to add optional silence. Thank you.

Yes, there are newer Bluetooth headphones with significantly lower latencies, either through LE Bluetooth audio or through codecs like AptX LL.

Most reviewers are already utterly unable to measure "normal" latency. In the very ridiculous chance you'll find a reviewer measuring wake up latency (which has little to do with the codec used), I wouldn't even trust it.

Yes, wake up latency is going to be a crapshoot, but you can eliminate it by playing a silent file at the expense of battery life. Actual latency though there's nothing you can do about it, so it's more important imo.
