Get the long ISO version instead of using the default comfort ones. They are slightly longer and will put a little more distance between the shell and your ears.
I have both, but I have no comfort issue with the default round ones so I didn't change them out. However, the T-500s are longer, so it will give you a mm or 2 so the bore doesn't have to be so deep inside your ear. I ran into a similar problem with my Bowers & Wilkins C5 and this was how I fixed it.
i think you have the wrong bud on ur left ear lol
When you wear down, you swap left and right... The connectors are amadextrius (or however you spell it) though. So left goes into right, right goes into left... Again, only when you wear down.
If you were having comfort issues, try swapping them, it should make them a hell lot more comfortable.
Then you should really get a pack of T500 and have your problem fixed. Also, when you use the Comply Foam tips, make sure you squeeze the crap out of it, then insert them into your ear and let them expend. That way you will get a good fit.
Ambidextrous do you mean?
I posted about an aftermarket cable, the FiiO RC-SE1, a while back on this thread.
