Just bumping for an update here.
I have seen the white bi-flanges in one of the reviews here, but my sample did not ship w/ them. I have a long, clear bi-flange and a shorter, transparent bi-flange along w/ the assortment of single flange black tips.
To my ears the longer, clear bi-flanges sound the best, but I've some T-400's from Comply laying around and while they do sound a bit more dull, the comfort is MUCH better IMO.
I've yet to try the Olives, but was just wondering if there were any other options out there over the past few months.
Cheers!
