finally, after a loooong research stint that got me to join Head-fi, i bit the bullet and went in for my first high quality headphone. the M50s! i livbe in india and prices here are stupid high. i bought one for approx USD170....
i went in for the coiled one. i picked it up from a distributer and only had my Samsung mobile to try em out with. needless to say, they sounded nothing better than the Bose In ear i was hearing. the bass was pretty boomy and the mids had is kind of hiss to em.
i went back home and set up the playlist for burn in session. i chose songs like Symphony 25 by Mozzart, Telephone by Lady Gaga, Nostalgia by Yanni, Paradise Lost by Symphony X, Ecuador by DJ Sash, etc... so basically covering the spectrum of music that i listen to.
after about 1 hour, there is a clear difference. this is definetly a bassy product! the bass was louder but more pronounced and controlled. as the session progressed, i notice only one thing that ill call negative. the hiss in the mids have stopped but they have become more elusive and recessed. but still very audible because of the excellent NC by the large earpads.
i have finished about 8 hours of burn in and will go home from work and try em out.
will post updates.
