My Impressions M80 vs M100
I had M80's first versions and now own the M100's. The family of curves have certainty changed over time, but what I can say is that the bass is more present, I've always felt that the M80's lacked a little in the bass dept. so from my perspective these M100's are Axiom perfect little secret.. are they worth the upgrade? if you have an older version of the M80's like 1 or 2 I would have to say yes... if you had version 3 hummm that would be a good one.. M80's HP vs M100... I would have to say M100's all day long
