I've been having this problem too (Trekz Air and Aeropex) and I've figured out my problem. Looks like if you reduce the mic input level setting to zero then the Mac tells the headphones to mute. I had my Zoom audio settings set to "Automatically adjust microphone volume" which causes it to reduce the mic input level to zero whenever it thinks you are not speaking, which triggers the headphone mute. I have disabled this option and now I don't get the constant muting. There is a similar setting in Microsoft Teams (Devices --> Automatically adjust mic sensitivity) which you also need to disable.
