So im saying they dont think these things through as well as they could. Also, when they get wet, they make a funny squeeky noise. The sound stage is also pretty good. The hard rubber strap that fits between your toes digs into to your skin. Bought to replace a previous pair that were, literally, falling apart on my feet after years of sterling service. They where a little snug when I first put them on but now they are perfect and I sure wish I had these two years ago. It also helps with back support. I liked the stiffness of the boom with the over the headband but after 3 hours could tell that even though the pressure is less than my A20 there was pressure there compared to products like Clarity aloft headset that have no over the top headband. Here is what I found:N O I S E C A N C E L L A T I O NBOSE: These have the best noise cancellation by far. Ahora que ya los he podido probar, no son tan buenos como se describen, el micrófono no es tan malo, pero, no es bueno, sin embargo, por los que yo los compré, no funcionan como dicen que deberían, el audio es claro, pero no tan bueno como unos audífonos comunes.
