I just want to start the review making sure people are not confused by the Amazon description. This headset does not have active noise cancelling and you will hear everything around you while using it. What it will do is cancel background noise picked up by your microphone while you are talking to someone else to make sure your voice is clear.With that out of the way... this is a great headset, with good range and the microphone sounds slightly better than some of the competitors at this price point. I was surprised by the sound quality and it's more than adequate to play music while working. In terms of ergonomics, it's ok but not amazing and I can wear it for multiple hours without feeling uncomfortable. It stays in place just fine if you don't move your head too much but it starts to fall a little if you look up and down due to its weight.Battery life is very good and it was extremely easy to connect to a Mac, Windows laptop and an iPad. It can hold two active connections at the same time which works great between the Windows laptop and the iPad but not that well between the Mac and the PC which seems to be a problem based on other reviews.The USB dongle worked fine and has a little LED light that shows whether you are muted/unmuted or in a call. The Windows software is easy to use and configure and it detected everything without problems. Updating the dongle and headset to the latest firmware versions just worked.It's a premium (expensive) headset but it delivers, I definitely recommend it.
