What is the difference between the older m8 and the newer Mg7? I'm just curious. I have an older pair of M8 and really enjoy them. I bought them 5 years ago and really didn't expect them to last this long. As any red blooded gear head I bought other iems for various reasons and the atrios were deleagated to some of the rougher treatment like going to the gym (currently I'm in Afghanistan) largely because I figure I've gotten my money's worth out of them and I'll spare the newer iems the wear and tear. Anyway, these things just keep going! They sound and function as good as the day I bought them.
Anyway, I'm just curious. I'm not likely to buy a pair any time soon as I am saturated with iems right now but its good to know and keep up with whats going on. Are the M7s a big improvement from the m8s. If not what was the point?
