These are the 2 I am looking at, http://www.newegg.com/Product/Product.asp?Item=N82E16826106346 and http://www.newegg.com/Product/Product.asp?Item=N82E16826106381 All of the specs are the same, except the ear muffs, and USB adaptor on the 155. I usually game for long periods of time (4+ hours) and I am thinking that the 150 will hurt my ears in these long gaming sessions. Does anyone have any experience with these headsets?
