Who's the manufacturer of the tri-flange?

Well I have some status to report. I experimented with the Westone silicone and foam as well as the Complys. I've concluded that I am definitely not a foam guy. I find them hard to insert, even after kind of rolling them back and forth to flatten them a bit. And even when they're in, they don't...

Ah, I see those..thanks. I ordered the "combo" kit with foam and silicone tips. For $16, it seems like a good move at this point. Thanks all...Scott

Did a little research on the Westones...seems they come in silicone and foam. Which one are you guys recommending? The silicone ones look like every other silicone type so what's so special? Is the silicone thicker than the stock silicones? Also, not sure they will work with the Klipsche x10 ear...

Yeah, my main problem with my Klipsches is that lose their seal. In fact if I simply smile, I guess the ear canal changes shape and the seal is lost which, as you mentioned, seriously degrades the sound (mainly bass). Its a big problem as the primary use of IEMs for me is when I'm working out...

Also, one other question for those that have owned the 846s, was there a period of time necessary to get used to the over-the-ear fit?

I am seriously considering purchasing the SE846 but would like to get input on their "staying power" when working out, i.e.: the potential for them to lose their seal. My current Klipsches which are very good IEMs use silicone tips which lose their seal when my ear canals sweat....Any thoughts...
