Hi. I've had the original sennheiser cx300 for many years and i lost them, so i need to replace them with something better i hope. I listen mostly to metal bands like In Flames and Soilwork, but also the occasional electronic music like Chemical Brothers, Prodigy and Pendulum. So bass is essential, but not a muddy mess. The CX300's were fine, but could have had more defined bass and clarity. I have been looking at Sennheiser CX300 II's and MEElectronics M6. Anything else along those lines that is better suited for my music style? What would be my best bet?
