I feel like the M9 is a safer bet. When I was at e-earphone in Tokyo, the Z1R took forever to get to fit right with its giant shells whereas the M9 was a seamless fit for me.
Once I got the Z1R to fit well, it definitely was an improvement in the bass department but the M9 was just so relaxed both in fit and in sound that I ended up with that. Would definitely recommend you go somewhere you can demo first before you buy either one however.
