There's more you can add to the list like the Sennheiser IE8 and Audio Techica CK100.
Frankly, there's a lot of great IEMs. Not all need to be $300 though, and products like the Eytmotic ER4S and Phonak Audio PFE are outstanding products in their own rights at half the price. Even something like Denon's C751 or Head Direct's RE0 are very good products at just a third of the price.
In the end, it all comes down to the specific aspects you are looking for, your personal preferences. These will determine which earphone is a best fit for you personally. Something will function darn near perfectly for your own, specific preferences. The hard part is finding which products actually fit those preferences well. It can be quite a challenge, even if you have a lot of reviews and user comments to fall back on. I do find a lot of the comments decently accurate, but it takes a lot of data collection to get a good big picture view of a product, at least enough so where you can make a sound judgement.
A lot of the headphones I've mentioned I've run. I recently purchased the Triple.Fi but have never used the SE530 or Westone 3 or UM3X(not sure the difference), or CK100. You will find a lot of earphones do certain things wonderfully, but it's very hard to find something that does everything wonderfully. I've liked a lot of the earphones I've run, just for different reasons. Some were a better fit for my personal tastes then others.
