This is a fantastic work headset. Its comfortable, the mic is excellent quality, there's good active noise cancellation, battery life is good... It has everything you'd want in a work headset. And it even works for listening to music too.

I used this on two different computers by just plugging in the USB A receiver. It paired quickly and both MacOS and Windows had no issues recognizing it as an audio output and input. The signal was strong enough to go through two walls without dropping audio quality.
The mic is really nice. When the headset is sending mic audio back to the computer, it will warn you when you're muted or unmuted both with a visual cue and with a voice in your ear. And it works on both sides of your head - all you have to do is move the mic up and out of the way. I did not test pulling the mic away from my ear to mute since I normally move the opposite ear-cup from the mic away to listen to what's around me.
Speaking of which, noise cancellation is very good. White noise like furnaces, fans, washing machines all disappear. Even though it's an on-ear design, I was impressed with the noise cancellation.
Battery life is really good too. I didn't do any detailed measuring but this headset will easily last you a workday or more. And the cradle is an easy way to store and charge the headset at the same time.
Audio quality when you're not using the mic is really good. The sound quality is good enough that you won't mind listening to music with these at all. Sound quality does drop when you're both sending and receiving audio. I noticed this when I fired up a game while wearing these. Game music in the menu sounded good but as soon as I joined a voice channel, the audio quality dropped and changed equalization to focus on voices more than music it sounded like. That was the only aspect of these headphones that made me know these were designed for work. Everything else about this headset is so nice you could probably use these as your every day headphones without ever noticing that they're designed for work.

Anker has made a great work headset. If you want something for work that can easily do double duty, these are a great choice. If you just want a good work headset so that your colleagues can hear you in a virtual meeting, these are a fantastic choice for that.

This headset is AMAZING! It is an investment, but it's very much worth the purchase.

The quality of this headset rivals the much more expensive brands. The active noise cancellation works great. The one awesome feature that I wish every headset had was to mute the microphone when flipped it up, this especially comes in handy when you quick have to run to the bathroom in the middle of a conference call.

Loved this head set after struggling with a lot of brands I was finally able to find this one and it’s totally worth the money! When I’m on calls they can hear me clearly! The smart mute function is awesome. You can change the settings on the app on your phone if your computer is old (I loved that). Just awesome! I told all my coworkers about this head set and they already ordered one !
