Summary: This headphone is very good. Great sound all around and balance between the high-mid-lows. The low impedance makes this headphone easy to drive from ipod or general mp3 players and don't really require an amp. The coiled cable is very nice as it is not too long and can be bundled up. Since these headphones are not open headphones and the ear cup makes a complete seal, my ear gets sweaty when it's hot. Also, the leather looks like will go bad over time from wear.
Summary: Hooked these up to my Yamaha Motif xs8 keyboard and they sound amazing(coming from Panasonic RP-HT722)The bass is not too heavy but can deliver it and the highs are clear. Also use them for movies and gaming on my computer. Got them off of amazon a while back.
Summary: The newer white M50 sells now for about $160 to $170 USD, and the sound compares well above the $250 range in my opinion. I find a very slight treble peak and/or sibilance on some tracks, a small midrange coloration, and a bass that actually increases slightly below 50 hz to about 30 hz. The bass can get slightly boomy or muddy on perhaps two percent of my music tracks, which in my view is a bargain price to pay for the bass extension and impact at this price level.
