Is Westone ES60 better then other CIEM out there?
Is it worth the price?
I can say the ES60 are better than my Livewires, custom SE530, ES3X, UE 11 Pro, JH13Pro, ES5, JH16Pro, and tied with my JHA Roxanne only when the Roxanne are amp'd with a low output impedance amp. Out of an iPhone 6 or HM901s the ES60 win every time. See review in my sig line.
They are worth the price, and may be the best bang for the buck. While the W60 are my favorite Westone universal fit IEM (having heard all but the W50 or UMpro50), the extra $300 gets you faster punchier 2x stronger bass, and a bit smoother treble, with much better comfort for >2 hour listening sessions.
There is only one person who can answer this question, and I don't even think he has ES60:

I have ES60 and absolutely love it. The best CIEM/IEM in my collection, but it means nothing since it's relative to whatever I have tested so far, and I haven't even scratched a surface of CIEM/UIEM flagships, such as K10, A12, Jh Layla, etc.
The ES60 are my favorite too. I like the Layla universal fit more than my Roxanne customs or universal fit Angie. But I haven't compared ES60 to Layla universal fit because I didn't have time at RMAF this year (only got my ES60 the day before RMAF ended). I'd guess they're on a similar level, but it's a guess from having heard them on two different days.
I haven't heard a lot of the others out there either. My FreqShow and Alien Ears C3 were bad bad bad, gave them away. I've tried unique Melody and Aurisonics demos and liked them, and I'll be beta testing some from UM next week. This market has just blown up from before when all we had was the big three (UE, Westone, and JHA) and a few "also rans" that popped up in 2008, now there's so many that people don't know where to start.
I do know I haven't heard a bad custom from Westone or JHA but I only have the three different models above from each of them. My UE11Pro were fantastic from my Woo WA6 and sucked from an iPhone 3GS/4/4s, and to honest I haven't pulled them out to listen for years. Well amped I thought the UE11Pro sounded like a well modded Denon D7000, but poorly amped they were like a stock D5000. I probably should see how they do from the iPhone 6+ now (as well as re-trying my ES3X which sound like a well amp'd HD800).
