It serves as a great platform for carrying the Smittybilt rooftop tent on my Chevy Colorado ZR2. It would be great to see these packaged with no plastic. and it does control dandruff like regular head and shoulders. The fit was perfect anyway. I bought some for my mum and they were perfect but I had to send these back to my sons disappointment. When in the real world (like at the gym) there is no discernible difference between the noise canceling settings. I searched and found these headphones and they are GREAT! What did I get for what I paid. Ive had these for a few months. problemo solved!
