Bluetooth audio is choppy / stuttering on Macbook Pro (Mojave) but not iPhone Audio playing from my Macbook Pro (Late 2016 15" w/ Touch Bar, OS v10.14.6) to my true wireless earbuds (Jabra Elite 75t) is often choppy / stuttering. The problem seems to be with the Macbook because audio playing from my iPhone 8 Plus to the Jabra earbuds never stutters. I can't upgrade from Mojave to Catalina because I use some legacy software.

Things I've tried:


Unpair/re-pair
Bluetooth menu -> Debug - Reset the bluetooth module
Reset PRAM
Disconnect wifi
Disconnect iPhone &lt;-> Jabra connection
Change Sound settings for Input to Internal Microphone rather than Jabra
Set AirDrop to be discoverable by no one
Jump between wifi 2.4Ghz and 5Ghz and change channels
Jabra firmware upgrade
Play audio from different apps (Spotify, VLC, Youtube on Chrome, etc.)
Try these commands (in particular the ones under EDIT 3 and EDIT 4) for improving the power/bandwidth for the bluetooth module.
Try the "Force AptX" option here, that made my sound much worse.


When I open Console.app and filter for faults or errors plus the term "bluetooth," all I see is the error message "CoreBluetooth isn't advertising for this client type" from process "wirelessproxd"; not sure what that's about, maybe something to do with AirDrop.

What else should I try?

Many thanks
Looking at support documents at Jabra, the earbuds aren't designed for use with a computer:

No, we do not recommend you pair your Jabra Bluetooth device directly with a computer. Jabra Bluetooth headsets are optimized to be used with other Bluetooth devices, such as, smartphones or tablets. They are not optimized to be used directly with a computer. We cannot guarantee device performance or provide support for performance problems that may result from this.
If you choose to pair your Jabra Bluetooth device with a computer, it could work for audio streaming, but not for call control, which is not supported by many computers. Also, audio quality could vary depending on the model of the computer.
