Pros: sweet vocal, detail highs, just enough bass to rock
Cons: not yet found
Got M-80 and becomes my every day headphone since early this year.
I don't like the stock cable with phone control buttons so I make a custom OFC cable, sound is a little bit improved and become smooth.
Most of the time I am playing 40% pop, 30% jazz and 30% classical, not so many dance music.
Today I brought an album "Random Access Memories" by Daft Punk, this is the number one album recently on many charts. I know why, the sound is so rich and dynamics with M-80 , make me rock with music, and I never think M-80 can deliver this level of sound at its compact size.
Highly recommend M-80, it is all rounder everyone knows, it even works on electronics dance music!
