If you want what they use in places like the Senate and other Big Boy meetings, get a Shure MX418D/C and a real external audio interface with phantom power. I use mine for gaming, and while it's totally overkill, it's a purpose-made professional quality desktop voice mic. They're tanks and will last 20 years. You can buy replacement parts for them. They're also on eBay for ~$120 if you keep an eye out. Pair that mic with something like a Focusrite Scarlett Solo (~$110), Zoom UAC-2 ($250), Universal Audio Arrow ($500, has built-in DSP accelerator [offload]), or something crazy overkill like a RME ADI-2 Pro ($2000), Antelope Zen Studio+ ($2500), or an Avid HDX system (~$5k with Pro Tools) with external Neve preamp (~$3500) and a Neumann U87 Ai ($3600) mic. That's if you're trying to record the next Grammy Award-winning track and have an unlimited budget to get world-class audio. For reference, something like a $400 Shure SM7B is what you'd hear on most broadcast radio stations. https://www.youtube.com/watch?v=ZpU6H2EtjLI has a comparison of the $3600 Neumann U87 vs the $230 Rode NT1-A for comparison. You won't be able to hear the difference over a conference call.
