Logitech MX Master 3S Bluetooth Issue / Lagging / Delay

I am referring to this closed thread: Logitech MX Master 3 / keys lagging. - Apple Community


Basically I am trying to understand the exact problem. After having googled and researched a lot, reddit as well, I found that when I disconnect my Sony WH-1000XM4 the mouse works supersmooth. But when it's connected it doesn't.


And at this point I don't think it is interferences as mentioned in some results I found. I feel like the bluetooth capacity is overloaded with this:


  • 1 Keychron Keyboard Bluetooth
  • 1 Logitech MX Master 3S
  • 1 Sony WH-1000XM4


It kinda would make sense to me that the Headphones would take the most bluetooth "bandwidth" but I am asking here if that makes sense. What Limit is there on bluetooth bandwidth and does it make sense that even though those are just 3 devices they can clog each other - or that the Headphones clog the mouses data?

Had same issue with Logitech MX 3s on bluetooth connection.


I used these devices over bluetooth:

  • Logitech MX master 3s
  • AirPods Pro 2
  • Bose QC 45
  • Nuphy Air75 Keyboard


Steps I tried:

  • Tried to reinstall LogiOptions+ - no luck
  • Removed all permissions, still lag
  • Restarted bluetooth daemon, still lag


Finally I removed all bluetooth devices that were listen in bluetooth settings but not connected: Lag has gone!


Strange but it worked 🤷‍♂️
