I did a webinar last week for The Experts Bench (TEBWW.com). They kindly sent me a Snowflake USB Microphone (made by Blue Microphones, $45, #BlueMicrophones).
Wow. The sound quality is radically better. Crystal clear. Just plug it in and it works.
If you’re doing webinars, podcasts, or presentations, get a better microphone.
I also use a $90 Logitech webcam. Very good image for the viewer.
Tip: clean your lens.
Tip: When you’re not using it, cover it. Hackers can look through your webcam. Just use some black tape.
