Decide between USB (plug-and-play simplicity) and XLR (professional, requires an interface). Choose dynamic mics for untreated, noisy rooms (podcasting, gaming), as they reject background noise. Available from $9.95.
Microphones have almost no ongoing costs. They do not consume notable electricity. Over long periods, minor accessories like foam windscreens or shock mount bands may need replacement. Total cost is mostly the upfront purchase of the mic and an audio interface if required.
Common Failure Modes
Microphones generally fail due to physical trauma, like being dropped. Condenser mics can suffer from moisture damage to the capsule from breathing or humidity. Dynamic mics are incredibly robust and rarely fail under normal use.
