Noise cancellation while driving is very good, this headset may not be for the professional truck driver but for the average person in a automobile or working around office or house this would be an excellent choice. They fit me true-to-size 6. There was a small bit of tuning to get the angle right but Its locked down and working great. I think this rack is perfect. The material is super soft and warm, perfect for fall/ winter. These shoes are incredibly flexible and soft, which we wanted for our toddler when she was just starting to walk and wanted to walk outside with us. Once again, thank you Logitech. However, the instructions were entirely in Chinese. just with everything else, its not great. My computer fans are usually noticeable as well.
