I have the same kinds of problems with Microsoft Teams. In my case the audio is often garbled and unintelligible, lots of dropouts due to multiple people speaking at the same time, and even on a good day it sounds like everyone is meeting in the bottom of a garbage bin.

I've tried various conferencing pucks (EMEET Luna 360 and M0, Jabra 410 and 510, both hard-wired and Bluetooth) and none of them seem to work well with any of my systems (various late model Dell Latitude and Inspiron laptops, mini- and micro-towers) running Windows 7 / 10 / 11.

I've also tried various models of iPads and iPhones, and the audio is just as bad. Pretty sure it isn't a connection issue either (FiOS with constant 1Gb up and down).

Would an external DAC help? Headphones or earbuds with a good microphone? A dedicated portable system I can use for video conferencing?
