Sad to say they didn't work out for me. There were 2 issues:
The left-ear driver buzzed/rattled >100 HZ. It was especially noticable with low Bass lines.
A little Italian engineering seemed to mostly fix the rattle. Played loud tone sweeps. Slapped it
at 100HZ. ;)
But they didn't have the tone I like. I think the S-Logic ends up muddying up the lower midrange
and then it just nosedives the treble at the high end. Anyway didn't have that holographic sound that
the nearly 20 year old Sennheiser HD-414s have. Sigh.
I'll see how these sound next:
