TL;DR fix

Recommended Troubleshooting Tool

The Symptom

Significant delay between a person speaking on screen and the sound in your ears, or frequent audio "pops" and crackles.

The Fix

Force High-Bitrate Mode (AAC)

macOS sometimes defaults to low-quality SBC. In Terminal:

Increase Bluetooth Bitpool

sudo defaults write bluetoothaudiod "Apple Bitpool Min" -int 40

Reset Audio Core

sudo killall coreaudiod

Pro Tip

Wi-Fi interference on the 2.4GHz band is the #1 cause of Bluetooth lag. If possible, switch your Mac to a 5GHz Wi-Fi network.
