Hello, I have a 3.5mm microphone and it produces pretty loud static sound when it is plugged in the front jack. If I plug it to th back of the case the noise is lower but is still present. Someone suggested that USB microphones do not have static noise, is this true? Would an 3.5mm to USB adapter work or I need a new USB microphone? Thank you.
 
Solution
When you plug a microphone via a 3.5mm jack, the connection is analog audio. This means any wiring or connection problems can cause noise.
A USB microphone (usually a USB headset with microphone) contains the audio device in the headset or microphone. There is no analog audio back to the computer. You won't get any noise from the wiring or connections.

In both cases, the quality of the microphone makes a difference as well to the sound quality you get.

There is no such thing as a 3.5mm to USB adapter.
You could get an external USB sound card and plug the 3.5mm microphone plug into that, but then you still have possible noise from the 3.5mm connection. It might help because the connection is better and because the external sound card may be better quality than the onboard sound.
Some headsets come with a device like this.

I suggest you look at a decent USB headset instead:
Corsair Vengeance 1500
Logitech G35
 


You will see this adapter as a playback device and a recording device in Windows. You would need to make this the default communications device rather than the onboard sound you are currently using.
In that little adapter is an audio encoder and decoder (codec). For $5.99 it is probably not great quality.
It might be better than the front audio ports of your case, since the wiring for these is often pretty crappy.
It is unlikely to be better than plugging your microphone into the rear of the PC.
