Chef Guy agrees with Leo that the so-called "Zoom fatigue" is setting in. Could it be due to bad audio quality? Leo says that could definitely be a contributing factor. The better quality audio you provide, the better. But most people Zoom using their computer laptop microphones. Would a lav and earbud microphones help? Leo says that a better choice is a Plantronics Model 540 or 478 USB headset. But good luck getting them these days. Those would give you the best audio quality for video conferencing.
Another option is the Samson C01U. Walmart is selling them for under $100.
