This headset is nice and comfortable, and the noise cancellation works great! I tested to see if my desk phone ringing would be audible while I was on a call through my computer on the headset, and it was effectively filtered out. If I try to talk while on mute, a voice quickly says "Muted", which is annoying if my "talking" was just coughing or clearing my throat, but I'm sure I'll get used to it. The Teams button stays lit all the time while the computer is turned on, and I don't know how that will hold out long term, but it doesn't get hot. The cord is still kinked a little from its initial folding after a few weeks of use, but it might straighten out over time. The microphone works on either your left or your right, depending on your preference.
