Maybe you can help me. With the stock tips these headphones sound fine indoors. They give me pretty good clarity and thump, which makes me think I'm getting a good seal. But when I take them outside, I can hear all kinds of noise from the city, and it sounds like I'm not getting a good seal. Does that mean I'm not getting a good seal? And that there's more to these headphones than I could have ever imagined? That's why I'm thinking I need to change out my tips... I've owned quite a few earbuds, and usually these size tips I would change without even trying them on, because I know they're too big right off the bat. But somehow they fit me with this earbud.
I know your environment can change the acoustics of any headphones, but I never really used to have this problem with my Image S4. The difference between inside and outside use was very subtle.
Also to anyone that can't get these to fit right, try rotating the bud until the piece somewhat slots into ear. My wire is coming pointed a little more upwards than the pictures in this thread. I don't have particularly large ears, but they fit me just fine. And by fit, I mean actually staying in your ears. In fact, these are some of the most secure earbuds I've ever owned. It does feel a little uncomfortable at first, but I think that's just because I'm not used to wearing such a huge driver. I think those little spikes all around the outside are supposed to be mounting points to grip into your ear. That's the only reason I can think of that these stay put so well, despite being so big.
