ljokerl, Since had permanently lost my Senn HD555, i had to switch to my good old semi-broken Sony XB500 can. Semi-broken because both driver holders (the circles that clamp to the drivers) on the headband broke, so i had to hot glue my right cup, and use superglue on the left one, but it constantly breaks and i have to re-glue the left cup every other day. I'd rate the build quality of the headphones 3/10..
One question bothers me though, will the M50s have decent bass if i plug it into my iPod nano 5G without an amp? When i plug the XB500 the volume/low frequencies are quite nice, but will it be the same or better for M50s?
