“Wired microphone” covers several very different products. A stage vocal microphone may output analog XLR and require a mixer or audio interface, while a USB microphone contains its own digital interface and can connect directly to a computer.
Quick answer: For live singing, a handheld dynamic cardioid XLR microphone is a common starting point. For PC recording, USB is the simplest direct connection; a USB/XLR hybrid can let you start on a computer and later move to an interface or mixer.
Choose XLR vs USB First
| Connection | Best fit | What else you need |
|---|---|---|
| XLR analog | Live vocals, mixers, audio interfaces | Compatible mic preamp/interface and cable |
| USB digital | Direct PC/Mac recording | Supported USB port and operating system |
| USB + XLR | PC now, audio interface later | Choose the output path needed for each setup |
Stage Vocal Example: Shure SM58
Shure’s SM58 is a cardioid dynamic vocal microphone with a 3-pin XLR output and a published 50 Hz–15 kHz response. It does not plug directly into USB without an audio interface or converter.
PC / Hybrid Example: Audio-Technica ATR2100x-USB
Audio-Technica’s ATR2100x-USB provides both USB-C digital output and XLR analog output, plus a 3.5 mm headphone monitoring jack. The official setup guide documents both connection paths.
Dynamic vs Condenser
Dynamic microphones are common on loud stages because they can be rugged and work well close to the mouth. Condenser microphones can be more sensitive and often require phantom power or internal electronics. Neither category is universally better; room noise, source level and desired detail matter.
PC Compatibility Is About the Interface
An XLR microphone becomes a computer microphone through an audio interface, mixer or compatible USB converter. A USB microphone already includes digital conversion. Do not label an XLR-only model “USB compatible” merely because an adapter exists.
Wired Microphone FAQ
Can the Shure SM58 plug directly into a PC?
Not by USB on its own. SM58 uses XLR, so a computer setup normally needs an audio interface or other compatible XLR-to-digital path.
Does a condenser mic always sound better?
No. It is a different transducer category with different sensitivity and powering needs. The better fit depends on source, room and workflow.
Why choose USB + XLR?
A dual-output microphone can connect directly to a computer now while retaining an analog XLR path for a mixer or interface later.
