Interesting. Mine are more secure than stock in terms of movement and "fit". They seem to seal about the same. Adding smaller tips underneath probably adds to the density. I have a feeling the low density of the silicon affects things somehow. Not really sure. Either way, I've been using them all day, and the sound is 100% consistent every time I put them in. So whatever the reason I have found my tips! :-) And they are sexy...
The difference in how securely they fit in our ears may be related to tip size. I need to use the largest size and from the pic I'd say yours is smaller. The silicone is simply too thin, imo, to offer sufficient support for the largest tips.
I know people have tried these with little success earlier in the thread so I was hesitant, but I threw on the smallest MH1 tips anyway because I was hearing things differently anyway and viola. The bass sounded flatter and the lower mids didn't scream out at me as being immediately off.
Running a controlled sine sweep back and forth and back and forth soon after, and, from the first time, they literally sound exactly as graphed by that one guy.
Time to give them another critical listening session as they are now "reference", but I can tell it's a solid improvement already.
James, maybe they'll work for your ears too. Maybe worth a shot?
An ever so slightly leaky seal via smaller tips, or the front vent mod (which basically does the same), seems to be some sort of consensus for the bassy ones to get the best out of them.
@vwinter: my ears are like giant dark caverns, you could pour a dozen of those smallest MH1 tips in and would never see them again. Joking aside, for me it's the largest stock tips + front vent mod, not only do upper bass and lower mids sound noticeably less off, but they also sound more open overall, with better soundstage depth.
