First, search buddy, thank you for all you have done for me (recommendations, samples and some good advice to boot). Search is good people and have become a priceless head-fier friend. You are really appreciated buddy.
Stalflare, I have finally got my hands on some Sony Hybrids (thanks to some assistance from my pal search), and I will have to concur with rawrster. The Sony Hybrids so far have been the best tips for me in regards to the e-Q7. It just seems to boost the whole Orto sound spectrum, especially the highs that always seemed to be the only range a little recessed with the Ortos (although I'm not a huge treble lover).
I had originally thought the Sony hybrids would help my Monster Copper, but it was actually one of the worst for those IEMs. I was going to throw them away, when something prompted me to give them a try on the Ortos. Man! I'm glad I did. So I would rank tips for Ortos (for me) as Sony hybrid, and a tie between Comply T500 and the Xears orange foams.
I take the largest Sony hybrids (I think it's a teal color inside, but not 100 percent sure). These hug the Orto stemtight and should be placed all the way down where the stem meets the bass. They are somewhat of a challenge to get on. Remember stalflare that everyone ear is shaped different, so what I'm getting you may not get, but those Sonys are working for me. You just have to try a variety of tips, and sometimes you get lucky quickly. By the way, search's recommendation of the Sennhesier double flange is also a good option. I like those, but they take away some of the bass for me. The Sony enhances the bass for me.
