It is a cardioid microphone, where you have to speak into it from above, so the microphone is a. The sound quality is genuine and really very good!
Even if I'm 4 meters away from the microphone to smoke at the window you can hear me still as loud as if I'm sitting in front of it. What is good for TeamSpeak if you have a short time away. While I listen to me then ill and echoing to but something is the micro also not designed.
I can even whisper and you still hear me super.
And the hum what some ... so either you have a mounting production, or you take the PC humming along on or vll vibrations from the table, or simply have a bad sound card. I have virtually no hum.
Ie; when absolute silence is and I take the silence and + 10dB can lift you only hear a noise very very quiet. Not more and not before!
5Sterne great product! An on and off switch, I would have still required, but you can also deduct the cable to the microphone so not so bad :)
