USB connects a supported microphone directly to the computer. An XLR microphone normally connects through an audio interface or mixer before reaching the computer. The useful choice depends on what you need that whole chain to do.
Neither connector tells you how a microphone will sound in your room. Work out the placement, input count, headphone monitoring and full budget first.

When USB is the simpler choice
For one microphone into OBS on a computer, USB can keep the setup to fewer components. Check the actual port, operating-system support, cable, stand and headphone behavior of the chosen model.
Do not assume all USB headphone outputs provide direct voice monitoring. Wave Neo plays computer audio through its jack, while the original MV6 offers direct monitoring. That difference can matter in a live setup.
When XLR earns its extra parts
XLR can make sense when you need the inputs, physical controls, outputs or routing of a particular interface. Identify that requirement before deciding that an XLR chain is an upgrade.
Include the interface and XLR cable in your budget. Confirm the interface supports the microphone and the monitoring behavior you want. Our tool compares entered costs; it does not test interface gain, noise, drivers or routing.
What changes on a USB/XLR microphone?
AM8 and K688 can be used through either path, but the controls are not identical in both modes. Their USB headphone monitoring and digital controls do not become features of the XLR cable. Plan monitoring through the selected interface when using XLR.
This makes a dual-connection mic an option for a future change, not a reason to buy an interface immediately. Use the USB route first if it covers your current job.
Build two complete budgets
Compare the mic, stand or arm, required cables, any interface, delivery and tax in one currency. Count owned or included parts only after confirming that they fit. Do not compare a bare XLR microphone with a complete USB kit as if both were ready to use.
Use the tool below to enter those amounts. If a cost is unknown, the result stays incomplete. A lower entered total is a cost comparison, not a verdict on sound quality.
Before replacing your microphone
Make a private recording with the mic close enough for clear speech, suitable gain and the same background noise you normally have. Listen back before adding filters or buying another connection chain.
If voice is missing from a stream despite a moving OBS meter, check audio routing and output tracks. Changing from USB to XLR does not diagnose a track-assignment problem.
