Also, note that review is for the Kain 120 - Ive not tried the 10x or 20x versions. It was EXACTLY what I was hoping to get. This is my 3rd. I was so excited to get this in, but as I was putting it all together I noticed that there was no hole to attach my tricep rope. Now about the noise cancellation. I bought both the Tech Wash and TX. Marshal. Pero pues creo que prácticamente todo audífono de este tipo no pueden evitar esta pequeño inconveniente. It turned out being not so bad. The second one showed up all scuffed.
