Ever since I got my first portable music player, an RCA CD player 8274743 years ago I've always liked a clean sound, nothing too bass heavy. I had a pair of Creative earphones that came with my Creative NOMAD, which were amazing, certainly beats the iBuds. Alas, they broke (and eventually my NOMAD, even if it was a tank) so I went out to Wal Mart and picked up a pair of Philips with silicon tips and found the Creative's match. When I got my iPod, I didn't even bother with the iBuds.
I got a second pair of those Philips earbuds, and stayed quite content with them... Then, I went to Japan. I needed something that isolated, not noise cancel, so I started my search which led me here. After research, I started with the Super.fi 3s and were always enticed by the Triple.fi 10s, so naturally when Amazon had them at $99 the first time, I had to get them. I grew extremely attached to detachable cables, after going through four cables in one year for the Super.fis; my Triple.fis could use a new cable (after a year, though). The one IEM I wanted, though, was the Etymotic ER4Ss (I was drawn to their blue/red combo). One day a deal I just couldn't pass up came along and I got them and have been my main choice for portable use for the past two years.
I have been greatly satisfied for almost two years with the Etymotic ER4P/S... I am good for now, maybe going up to customs, it would be nice to be able to easily go to Unique Melodys but will probably just go with some JHs. When the funds can be sacrificed, of course.
Luckily, my portable/IEM upraditis has been, for the most part, cured... Unfortunately, home setups are more expensive (for me) and I have about four or five future purchases I am looking forward to, which don't include any new products.
