I was recommended these headphones after my old ones stopped working. I use them exclusively for work. Mostly Teams meetings, sometimes Zoom meetings. Overall, they're the best headphones I've used thus far.PROS:- Very comfortable. I have average-sized ears, and these fit over my ears like a glove. The ear cups are shaped such that your ears fit "inside" the cup padding, and the padding is tight against my head without interfering with the shape of my ears. I initially felt some issues with the headband - I was worried that it would give me that lingering head pain that I've experienced with inferior headsets. But that never materialized, and now they just feel good.- The sound cancellation is great. Enough that background noise doesn't interfere. I can't really say much more about this; it just works. If you're looking for absolutely no sound, this ain't it. But for a conventional home office room, it is perfect.- Sound quality. My colleagues say that my voice is very clear.- The controls. On the left, you spin the dial forward/backward to engage or disengage the sound cancellation. There's apparently 13 levels of cancellation; I just treat it as Yes or No. On the right is the volume - same deal. Spin forward to turn up, backward to turn down. There are other controls for calls, music, etc. involving tapping and I haven't really used these, but what I have used of them they work just fine. It's very intuitive.-General Operation. A button on the right side turns them off/on, and the mute button is just to the side of it. There is a sound that plays when you're toggling the mute and let's you know pretty distinctively whether your mute is on or off.- Connectivity. I use these with Bluetooth on a MacBook Air M1, and they're extremely responsive to connecting to my computer when I turn them on/put them on.- Look and feel. They are packaged wonderfully, have a very modern look, and present themselves as a very quality product designed with thought & attention. They have a "weight" to them that doesn't feel cheap at all.CONS:- They frequently produce garbled audio packets. I've been in meetings where the speaker's voice will get garbled regularly, almost as if their internet connection is slow. But others don't report this, so I'm pretty certain it's the headphone bluetooth connection. I'm not sure what is causing this. It's annoying, but ultimately only a moderate inconvenience because it's not so garbled that I can't understand what the other person is saying.- They sometimes get confused. If I have them registered with Bluetooth on my phone and my computer, they'll connect to both my phone and my computer, and when I have to switch between my phone or computer for a meeting or a call, they sometimes don't know which thing to connect to. I really don't think this is an issue with the headphones per se, but it's a thing. A very minor thing.- A quirk on Mac. This is entirely Apple's fault, but worth knowing. When these headphones are put on, Apple Music is brought up on the computer automatically. I haven't figured out how to stop this from happening. Again, nothing against the headphones, but if you are using them with a Mac it's worth knowing.Overall, I'm very happy with how these are performing. Despite the quirks, I'll give them 5 stars as the most superior headphones I've used for work.
