It's still significantly worse than aptX LL... Don't know what the big deal is.
The latency has to be ~20ms or better to be able to compose with them. Heres hoping for the day but I dont believe bluetooth is able to achieve that. He should know better.
The measurement methodology used here cannot be compared to other codec's theoretical numbers or be used as representative for pure audio applications.
If you read the article, he recorded the sound of an Apple Pencil tapping on the screen and the audio output from the headphones on the same mic, then measured the time between the sounds. Therefore, these numbers include the touchscreen and OS processing latency. This limitation is specifically called out in his article.
These numbers are only valid in a relative sense and do not represent, for example, absolute audio playback latency.
He should have conducted the same experiment on a pair of wired headphones as well to remove the processing they do on the built-in speakers, and characterize the USB transport latency.
