I also agree. Sometimes I speak to work colleagues who are on BT headsets and it must add what feels like 100ms to the call. I can sometimes hear the end of my sentence as I speak. Infuriating.
I don't understand how Bluetooth has made it this far for phone calls. It has two modes: unintelligible quality and bad latency, or decent quality and ludicrous latency. The entire standard is an advertisement for Airpods.
And that's on top of a ridiculously complex stack of protocols. I don't understand it either.
Is LE Audio going to change this to better?
What platform are you on? iOS/android/windows/macos/linux?
Mostly Windows and Android. Although both audio pipelines aren't great I don't think it's a platform problem--I've never seen a measurement of even 100ms lag with Bluetooth (excluding aptX-LL) and it's usually in the 300ms range. It also still only does two-way audio at 8kHz, which is unbelievable to me in 2021.
