After over 35 years in the telecom industry these scissors are some of the worst I have ever used. New scissors may be too loose, too tight, blunt and have no tips. I bought ten pairs of these headphones primarily as Christmas gifts last year for each of the guys I work with. Bought two more pairs for myself recently. The first pair was too tight and the second pair was very boring. Both pairs did not have scissor tips, making it impossible to remove the window from any of the panels we used. Back to Fluke or Klein
