I am not happy with this. I ordered my size and I can manage them, but putting them on isn?t as easy as I thought they would be. Its kind of a pain to use and carry around. The other 2 have almost a smooth matte-type finish with no brush strokes, while the "thumbs up" hand has a shiny finish and deep brush strokes all over it! I originally returned them because they were a little too small. So the headphones are amazing, fit well, long battery life, and worked great for about the first 4 days. I actually had to switch my few coats to my dress shirts so it wasnt as heavy. Its definitely a sturdy metal and seems that it will last quite a while! I tried many different treatments. Also important for river-wear was a slip resistant sole and these also are GOOD in that respect.
