At present, I'm using Blue SnowBall ICE. I'm very very happy with it. However, I felt if I'd be able to use anything that's head-worn, and obviously USB - would made my tasks more comfortable. I felt so, because, I'm using multi screens. When I move around screens to screen, the captured voice level daviated low to high or vice-versa. Here, USB is necesary to avoid any unwanted buzzy noise.
Thanks for your time while reading this post.
I use a lapel mic that cost £15 and record into my phone then upload it via USB link. The sound quality is crystal clear and it would give you complete portability to move around. I used to use a snowball but now I prefer this set up. I hope to publish my first course this week.
Thanks for your response. The set up is perfect for you, however, for my case, I mostly do screencast with multiple screens. Therefore, looking for Head-worn USB Mic. Otherwise, I'm living well with my snowball ice..
