firstly let me please iterate that I did not see Gclef's post as any form of a put-down to me, more a form of irony me being English (native language & all that)... my reply was a ironic riposte which was obviously lost on some.
as for the M-80, I see these wonderful claims that they are 'balanced.. wonderfully detailed.. great bass depth.. fantastic highs' etc etc, unfortunately I never heard any of that with my pair, that I eagerly forked out £170 for.... there was I, like an 'excited lemming on a cliff' waiting for the M-80's to arrive, when they did I was impressed with the packaging, the contents/extras were good, the headphones had real nice design and they felt sturdy in the hand, I was real impressed at that point... then depression set-in.
I can only surmise that if you have a good source with a wide soundstage the M-80's will sound crap, they are by far the worst sounding headphone I have owned in my short time trying to find a good portable set-up... perhaps I'm too spoilt by my home hi-fi system and expect too much from a portable-rig that said, I'm not going to 'sit on the fence' when I know personally that something sounds crap.
a lil adage if I may... falling for the hype once you can put down to experience, falling for it a second time will mean you're probably young or stupid.... I'll be waiting for the more sensible reviews on the M-100 tyvm.
