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 <-> 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

  • Does the MacBook play the audio without the glitches through a wired set of earbuds/headphones? – IconDaemon Mar 25 at 8:45
  • Yes audio plays just fine through wired earbuds and headphones. – lukeprog Mar 25 at 16:27
  • Luke, I'm having the same problem: Jabra 75t elite mic audio used to work perfectly with macbook pro 2013. Now the mic audio stutters and sounds robotic with a macbook pro 2020. Mic audio is fine and pristine with pixel 3. Very surprising to me. Here's a very useful discussion on Reddit about the same issue, with more insights but no solutions: reddit.com/r/Jabra/comments/f9bnfx/… – Doug M May 20 at 1:13

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.

  • Wow, that is surprising! Technically that document is for the 65t not the 75t, but I agree it's probably true for the 75t as well. It's a bummer the WireCutter review for the Jabra 75t didn't mention this; they seem to imply pairing with a laptop should work fine. This might help explain why I'm having a problem, but I'll keep the question open for now in case someone can recommend steps that might improve the audio reliability even if pairing with a laptop might not be officially supported by Jabra. – lukeprog Mar 26 at 17:36
