A good review, and I agree with most of your comments apart from your statement about isolation.
I personally think they isolate nowhere near as well as Etymotic IEMs.
I used to listen to Ety ER-6is on the Seoul subway and they isolated so well I literally couldn't hear any outside noise. With my HD25 1 II cans, I can hear the wheels screeching when the carriage turns a corner and can tell when the next stop is being announced.
They do isolate very well for full-sized headphones, but in my opinion it's an exaggeration to say they isolate as well as a good IEM.
