I got mine last week and I'm having quite a bit of trouble getting a consistently good seal. I don't have any tips that really fit me perfectly. I know the size of the shells themselves make it hard to make a deeper insertion, but at the moment I can only have them literally sit on the edge of my ear canal.
Anyone have any suggestions as to which tips I can try? I'm not very hot about having more bass - I'm a treble person (more on this end would be better, actually). The suggestions I've looked at are all about increasing the low-end.
