OK guys-
I'm trying to decide between the two, and have a question..
OK.. Here's the question..
The 13.4's are rated at a Passive Noise Reduction of 23db..
Whereas the 13X's are rated at a Passive Noise Reduction of 23db and an Active Noise Reduction of 20 db... So, is it safe to conclude that the 13X's will offer a "total" of 43db's over the 23db's of the 13.4's??
