Audacity Noise Removal Problem

So since I got Windows 10, I've been having a little bit of a headache with Audacity, for the record, I don't really have a mic though I do plan to have one (I currently use the Kraken Pro headset), but that didn't stop me before of making a vídeo with good áudio, I used to record the áudio on Audacity separaterely (on Windows 8.1) and then just apply noise reduction, and voilá, a vídeo with a pretty satisfatory áudio, here's one exemple:

The voice there is fine, there's a very little sound on the background, but it doesn't interfere with anything.

Now when I installed Windows 10 and Audacity, I noticed something, the noise reduction doesn't apply the same way, now when I apply it, it gives the voice a sort of echo-y feel to it which is quite annoying, though the program is exactly the same version, I'd like to know if anyone can help me out with this issue.

Here are two tracks, both on the current Audacity I have, one without Noise Reduction, and one with Noise Reduction:

You're not recording from the microphone you think you are: that's not the headset-mic , that's probably a recording from the mic built-into the computer, the echo is from the room you are in. You need to enable the headset-mic in Windows recording-devices , and choose the headset-mic as the device to record from.

You also didn't say which Audacity you have. Noise Removal before Audacity 2.1.0 did not do a particularly good job with voices. Noise Reduction in Audacity 2.1.0 and up works much better.

The many pop sounds would rather indicate that he's indeed recording through the head set, don't you think?

IMO It sounds like he's in front of the computer and inadvertently recording from the computer's in-built microphone : it's bassy and echo-y , as if he's approximately arm's-length from the mic.
I've made that mistake myself on more than one occasion.

If I'm correct, tapping the computer will produce a much louder sound than tapping the head-set microphone.

Whatever mic it is, the file posted on Soundcloud has serious DC offset which I assume Trebor corrected with Normalize.

If you are using Audacity 2.1.0 or 2.1.1, increase Frequency Smoothing in Noise Reduction (do not use 0 setting, which is off).
