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.
Cam has a USB headset that causes a bluescreen of death when he unplugs it, and then his USB ports stop working. Leo suspects that the USB driver is corrupted. It could also be a bad USB port or short circuit in the headset. But he should always test the driver. He should remove it in Device Manger - Windows Key + X, then select "Device Manager." Then let it reacquire and install the drivers.
Karen's new computer only has one port that she can connect and record from. How can she record and hear at the same time? Leo says to use a USB Mic. It'll do both, and it's digital. Far better than the minijack port for the microphone. Karen can use Audacity and it'll record directly from the source.
Most microphones on headsets are omnidirectional, meaning they pick up sound equally in all directions. He'll want something that's highly directional, though. Leo doesn't know of any inexpensive headsets that are directional. The one Leo uses and recommends is the Plantronics Dot Audio 995. It has a noise canceling microphone which might help reduce other sounds.
