The main parts work as expected (i.e., wireless connection, sound, microphone sound quality), but some of the buttons do nothing (mic button on the right, call button, teams button).
Also, this was missing the dongle, which I knew going in, but I would say it should be specified.
These headphones are awesome. The charge last over 30 hours, the headphones are comfortable, and you can walk a long way from your computer or whatever the headphones are paired to.
This headset is very well designed. The only negative is that it does not stay synced up with the Teams app when you mute and unmute on the app. You have to use the hardware button on the headset to stay in sync. I just need to train myself to use the headset button exclusively.
