Not that I need any more headphones (and I love the 1more's - even the mids), but your praise of the On2 is intriguing, and I have heard good things about them in the past.
And now I just received Massdrop notification for the On2's for $89 US. Things that make you go "Hmmm!".
They’re good. I got my On2 on a drop last month for $89 and they’re ridiculously superb at that price. Not as comfortable as the 1MORE but not bad for an on-ear as far as comfort goes.
