Diagnose before buying
Is the voice too quiet, distorted or full of keyboard noise? Move the microphone closer, reduce input gain where appropriate, and record away from noisy appliances. Test the same sentence before and after changing the position. You may improve the result without spending anything.
Decide how you will connect
A USB microphone connects to a compatible computer without a separate audio interface. XLR normally requires additional equipment. For a beginner recording a single voice, USB can simplify setup; XLR can become useful for a different recording workflow. Check the ports and supported software on your exact device.
One model to investigate
Audio-Technica describes the ATR2100x-USB as a cardioid dynamic microphone with USB and XLR outputs. Those features make it a candidate for someone starting on USB who may later use an interface. This is a manufacturer-specification shortlist, not a hands-on sound test or a claim that it is the best microphone.
Check the full setup
Look at stand position, available desk space, cables, headphone monitoring and the return policy for your seller. A close microphone that obstructs your screen may be annoying in real use. Compare the total setup cost, not just the product price. Amazon listings and availability vary, so verify the exact model before ordering.
When to skip the purchase
If your existing recording is intelligible and you have not yet made a complete lesson, finish one first. Buy when there is a specific sound or workflow problem the product is likely to solve. A tidy specification sheet is useful, but it cannot replace listening to recordings made in a comparable environment.
