Hi James,
Sorry to hear you are having these difficulties.
To respond, 8x8 Work works with any standard headset for basic audio operations, but please note that the quality of the sound will vary greatly depending on many factors such as CPU usage & connection type (wired, Bluetooth, adapter).
This said, please check out this link for compatible devices, I have checked on your behalf and could not locate the headsets you mentioned.(https://compatibility.plantronics.com/softphone)
I would also encourage you to try raising a support ticket for further help here. ------------------------------
