"Likewise noise in the rest of the room is almost non existent. Even when I clicked my fingers right behind the microphone it is barely audible. Full marks for ASUS for this feature.
The downside to noise cancelling is that unless you have the mic jammed right next to your mouth and speak clearly, you can sound quite far away and robotic. It’s something you can work around and is perhaps why the mic is quite rigid, so once you have found the best place for it it stays there. Just don’t expect to be using it at a distance, like you can with some headsets."
*So both appear SIMILAR in that there is amplification to the microphone (which is optional but necessary?) but the ASUS appears to have better NOISE CANCELLATION thus eliminating most background noise.
I believe by "robotic" that means the noise cancellation is also cancelling out some of the speech noise as well so less background noise but not as vibrant of speech.
I'm guessing the ASUS solution is preferable as you want clear voice commands but aren't recording a song.
