I was never able to overcome the random mute problem. However, I was able to abandon using my headset with Mac Mini (using Monteray iOS mentioned in this thread) altogether by simply connecting the headset to either my phone, laptop, and/or iPad (none of which uses the Monteray iOS) when I am in need ti use Zoom and my companies soft phone software. Since, I have experienced very little problems. Occasionally I have experienced sudden volume changes (which are regularly and easily remedied) though this typically occurs later in the day after prolonged use. Overall, I am still satisfied with the purchase despite some minor annoyances such as those described hereinabove. My last comment would include a request than future editions of the product include some method for adjusting the headset to fit more comfortably (particularly when either lying down, resting my head against a headrest, or when wearing my hair up in a ponytail) but the device is still so comfortable that at times I forget that I am even wearing them and am surprised when I suddenly hear sound so near my face! I use mine so frequently that putting them on have become as second nature as wearing glasses or putting on a bra. I definitely recommend to all my friends, despite anything in my posts that would indicate otherwise.
