I hope you'll give them another try, because with a good fit, good seal, and good amplification I find them anything but unconvincing.
After a lot of experimentation with the black foamies and the tri-flanges I thought I could get a good seal with the former and a decent, but a llittle bit inferior, with the later.
Out of pure curiosity I asked Etymotic to send me some samples (the send them internationally, excellent service) and to my surprise the huge yellow foamies were actually wearable. I thought that those were made for giants with ears the size of a frying pan but it is not the case. They can be squeezed very thin an are quite easy to insert and comfortable to wear.
And not only that. They turned out to offer the best seal and sound of the lot by far. The sound difference is amazing. Not thin at all to my ears.
Just a thought.
